5 Best Lift & Leveling Kits for Silverado 2500HD & Sierra 2500HD
Five manufacturer-verified lift and leveling kits for the Silverado 2500HD and Sierra 2500HD, from forged torsion keys to the only verified ZR2 and AT4X lift.
The Silverado 2500HD and Sierra 2500HD are torsion-bar trucks, and that one fact shapes every kit in this guide. There are no strut spacers here: leveling means forged torsion keys, and real lifts mean knuckles, control arms and differential drops. We verified five kits against their manufacturers’ own product pages — two for the 2011–2019 trucks, two for the 2020+ trucks, and one built specifically for the factory-lifted ZR2 and AT4X that every standard kit excludes. Full specs for every kit on this hub live on the Silverado 2500HD & Sierra 2500HD hub, and how we test and verify explains the standard each kit had to meet.
Short answer: level a 2020+ truck with the ReadyLIFT 66-30200, lift it with Rough Country’s 95830, and if you own a ZR2 or AT4X, skip straight to the Cognito 110-P1313 — it is the only verified option for those trucks. On a 2011–2019 truck, the ReadyLIFT 66-3011 levels it and the Rough Country 95730 lifts it properly.

Detailed Product Reviews
Last checked November 9, 2026
Key specs
- Front lift: 2″
- Rear lift: 0″
- Type: leveling
- Max tire stated: 34.8″
- SKU: 66-30200
Why we recommend it
The 2020+ GM HD still rides on torsion bars up front, so leveling is a key swap, not a spacer job. ReadyLIFT's 66-30200 replaces the factory keys with forged keys indexed for this platform's OE torsion keys, lifting the front 2 inches while the rear stays stock. ReadyLIFT rates the kit for a 35x12.50 tire on a 20x9 wheel at +18 or 0 offset, and is unusually specific about the limits: trimming may be required with some tire styles at 0 offset, Silverado and Sierra fender openings differ, and you should not crank the keys past 26 inches from wheel center to fender edge. It does not fit the AT4X or ZR2, and the install needs ReadyLIFT's unloading tool.
Best for: 2020+ Silverado 2500HD and Sierra 2500HD owners who want a level stance and a 35-inch tire without touching the rear suspension.
Pros
- ✓ Forged keys indexed for this platform's OE torsion key part numbers
- ✓ Stated 35x12.50 fitment with specific wheel offsets
- ✓ Lowest kit price of the five picks
Cons
- ✗ Does not fit AT4X or ZR2 models
- ✗ Requires ReadyLIFT's 66-7822B unloading tool, sold separately
- ✗ Trimming may be required with some tire styles at 0 offset
Last checked November 9, 2026
Key specs
- Front lift: 3″
- Rear lift: 1.5″
- Type: suspension lift
- Max tire stated: 34.8″
- SKU: 95830
Why we recommend it
Where the ReadyLIFT kit only re-indexes the torsion bars, Rough Country's 95830 goes further: forged solid aluminum upper control arms with pre-installed POM ball joints, differential drop brackets, forged torsion keys and 1.5-inch rear blocks for 3 inches up front and 1.5 in back. Rough Country stresses that it is 100% bolt-on with no cutting, and its tire table lists a 35x12.50R20 on 20x9 wheels at +0, +1 and -12 offsets with no trimming noted, even though the system was developed on a 295/70R18 and factory 18s. Shock and control-arm options move the price up from the base configuration. It does not fit dually trucks, the AT4X or the ZR2.
Best for: 2020+ HD owners who want more than a level — corrected ball-joint angles and a small rear lift — without cutting the truck.
Pros
- ✓ Forged aluminum upper control arms included, not an add-on
- ✓ 100% bolt-on install with differential drop brackets
- ✓ 35x12.50R20 listed at three offsets with no trimming noted
Cons
- ✗ Does not fit dually, AT4X or ZR2 models
- ✗ Price climbs quickly with shock and control-arm options
- ✗ Developed on a smaller 295/70R18 tire than its table maximum

Cognito 110-P1313: the lift built for the factory-lifted trucks
Last checked November 9, 2026
Key specs
- Front lift: 2.5″
- Rear lift: 0.5″
- Type: suspension lift
- Max tire stated: 36.8″
- SKU: 110-P1313
Why we recommend it
The Silverado HD ZR2 and Sierra HD AT4X already sit 1.5 inches up from the factory, with their front height coming from a re-clocked torsion lower control arm rather than a conventional lift — which is why every standard kit in this guide excludes them and why they have almost no droop travel stock. Cognito's 110-P1313 is the one verified kit built for them: a subframe and taller knuckles with differential drops that add 2.5 inches up front, a 2-inch rear block replacing the factory 1.5-inch block for half an inch out back, and billet clevis extensions that keep the OEM Multimatic DSSV shocks. Cognito rates it for a 37x12.50 tire and says it restores droop travel to 3 inches.
Best for: 2024+ Silverado 2500HD ZR2 and Sierra 2500HD AT4X owners — the only trucks in this guide the other four kits exclude.
Pros
- ✓ Only verified kit in this guide that fits the ZR2 and AT4X
- ✓ Retains the factory Multimatic DSSV dampers
- ✓ Rated for a 37x12.50 tire; droop travel restored to 3 inches
Cons
- ✗ By far the most expensive kit in this guide
- ✗ 37s on stock wheels need a spacer, a tie-back kit and medium trimming
- ✗ Pitman and idler support kit is a recommended extra, not included

Key specs
- Front lift: 2.3″
- Rear lift: 0″
- Type: leveling
- Max tire stated: 33″
- SKU: 66-3011
Why we recommend it
The 2011–2019 HD trucks use the same torsion-bar layout, and ReadyLIFT's 66-3011 is the straightforward way to level one: forged torsion keys that lift the front 2.25 inches, with four shock extensions in the box so the stock shocks stay on the truck. ReadyLIFT is blunt about the tire ceiling — 33 inches maximum diameter, with a 33x11.50 fitting with no rub on a 9-inch-wide wheel at +12 offset — and lists metric equivalents like 295/65R18 and 285/60R20. Install is quoted at about 3.5 hours and needs a torsion key unloading tool. If a 33 is all the tire you plan to run, this is the honest, complete version of the job.
Best for: 2011–2019 Silverado 2500HD and Sierra 2500HD owners who want a level stance and a 33-inch tire while keeping the stock shocks.
Pros
- ✓ Shock extensions included; stock shocks are retained
- ✓ Clear, conservative 33-inch tire ceiling stated by the maker
- ✓ Simple key swap with a quoted 3.5-hour install
Cons
- ✗ 33-inch tire cap rules out the 35s the newer kits clear
- ✗ Torsion key unloading tool required and not included
- ✗ Front-only lift; no rear components in the box

Key specs
- Front lift: 3.5″
- Rear lift: 1.5″
- Type: suspension lift
- Max tire stated: 34.3″
- SKU: 95730
Why we recommend it
For a 2011–2019 truck that needs more than keys, Rough Country's 95730 is a knuckle lift: precision knuckles, upper control arms and forged torsion keys lift the front 3.5 inches over 1.5-inch rear blocks. Rough Country's instructions say the system was developed on a 295/70R18 with factory aluminum 18-inch wheels, and its tire table lists that same 295/70R18 on factory 18s with no trimming noted, alongside a 33x12.50R20 on 20x9 +0 wheels. Shock choice — N3, M1, V2 or Vertex — is where the price moves. It does not fit dually models, and Rough Country recommends its torsion bar removal tool for the install.
Best for: 2011–2019 HD owners who want a genuine lift with corrected geometry rather than cranked keys.
Pros
- ✓ Knuckles and control arms correct geometry at 3.5 inches
- ✓ Four shock options from N3 to Vertex
- ✓ Developed and rated on the factory 18-inch wheel setup
Cons
- ✗ Does not fit dually models
- ✗ Stated tire maximum is smaller than the 2020+ kits clear
- ✗ Base price is for the entry N3 configuration
Buying Guide: Lift & Leveling Kits for the Silverado 2500HD & Sierra 2500HD
Torsion keys vs a full lift kit
A forged torsion key kit like either ReadyLIFT pick is the simplest job on this platform: swap the keys, keep the factory shocks (the 66-3011 even includes shock extensions), and accept the maker’s stated tire ceiling. A full kit — Rough Country’s 95830 and 95730, and Cognito’s 110-P1313 — adds control arms, knuckles or a subframe, differential drops and rear blocks, which corrects geometry instead of just cranking the bars harder. The honest dividing line is the tire: if the maker’s stated maximum for the key kit covers the tire you want, the key kit is enough. If it doesn’t, no amount of extra crank is a substitute — ReadyLIFT’s 26-inch wheel-center-to-fender warning exists because over-cranking keys is exactly how these trucks end up riding badly.
The ZR2 and AT4X problem
The Silverado HD ZR2 and Sierra HD AT4X (both from 2024) arrive with a 1.5-inch factory lift and Multimatic DSSV dampers, and their front height comes from a re-clocked torsion lower control arm rather than a subframe or knuckle lift. That leaves them with very little stock droop travel and makes them incompatible with standard HD kits — ReadyLIFT and Rough Country both exclude them by name. Cognito’s 110-P1313 is engineered around the problem: it keeps the DSSV shocks on billet clevis extensions, restores droop travel, and is the only kit in this guide those trucks can use. If you own one, the shortlist is one kit long, and any seller offering you a standard 2020+ kit for a ZR2 or AT4X is selling you a return.
What the makers actually claim for tires
Every tire number in this guide is the kit maker’s own published figure, not a forum report. ReadyLIFT claims 35x12.50 for its 2020+ keys and caps its 2011–2019 keys at 33 inches. Rough Country lists 35x12.50R20 for the 95830 and developed the 95730 on a 295/70R18. Cognito claims 37x12.50 — for the ZR2 and AT4X kit only. Read the offset and trimming notes before you order tires: several of these fitments are offset-specific, ReadyLIFT flags trimming at 0 offset, and Cognito’s 37 on stock wheels needs a spacer, a tie-back kit and medium trimming.
What we left out, and why
BDS Suspension sells HD systems for these trucks, including a 3-inch coilover conversion for the 2020+ diesel trucks — but in this pass only its installation documentation surfaced, and we could not verify price, SKU and exclusions from BDS’s own product page to the standard the five picks met, so BDS is not listed rather than summarized from retailers. Kryptonite, Zone Offroad, Fabtech and Torc were likewise not verified from their own product pages in this pass. ReadyLIFT’s taller SST kits for the 2020+ trucks were also left out: the verified picks already cover the leveling and 3-inch slots, and we do not pad a guide with near-duplicates.
🏆 Our Top Recommendation
ReadyLIFT 66-30200: the forged-key level for the current HD
It is the cleanest verified way to level a 2020+ HD: platform-specific forged torsion keys, a stated 35-inch tire fitment, and the lowest kit price in this guide — with the ZR2 and AT4X exclusion stated up front instead of buried.
The 2020+ GM HD still rides on torsion bars up front, so leveling is a key swap, not a spacer job. ReadyLIFT's 66-30200 replaces the factory keys with forged keys indexed for this platform's OE torsion keys, lifting the front 2 inches while the rear stays stock. ReadyLIFT rates the kit for a 35x12.50 tire on a 20x9 wheel at +18 or 0 offset, and is unusually specific about the limits: trimming may be required with some tire styles at 0 offset, Silverado and Sierra fender openings differ, and you should not crank the keys past 26 inches from wheel center to fender edge. It does not fit the AT4X or ZR2, and the install needs ReadyLIFT's unloading tool.
Best for: 2020+ Silverado 2500HD and Sierra 2500HD owners who want a level stance and a 35-inch tire without touching the rear suspension.
Final Thoughts
Start with your generation and your trim, because on this platform those two answers eliminate most of the catalogue. A standard 2020+ truck levels cleanly on ReadyLIFT’s forged keys; a 2011–2019 truck does the same with the 66-3011 and lifts properly with Rough Country’s knuckle kit. And if your truck is a ZR2 or AT4X, the Cognito kit is not the premium option — it is the only verified one. Buy the kit whose maker-stated tire size matches the tire you actually intend to run, and budget for the unloading tool and an alignment either way.

Frequently asked questions
Why don't standard lift and leveling kits fit the Silverado HD ZR2 or Sierra HD AT4X?
Because those trucks are already lifted 1.5 inches from the factory and get that height differently: the front uses a re-clocked torsion lower control arm and Multimatic DSSV dampers instead of a conventional lift. ReadyLIFT states plainly that its 66-30200 does not work with AT4X or ZR2 models, and Rough Country excludes both from the 95830 for the same factory-lift and DSSV reasons. The one verified kit in this guide built for them is Cognito's 110-P1313, which works around the DSSV shocks instead of replacing them.
How does leveling work on a Silverado 2500HD or Sierra 2500HD?
These trucks use torsion bars for the front suspension, so leveling means changing the torsion keys. A leveling kit replaces the factory keys with forged keys indexed differently, which rotates the bars and raises the front without a spacer or strut change. ReadyLIFT's keys are indexed for specific OE key part numbers on the 2020+ trucks, the install requires a torsion key unloading tool, and ReadyLIFT warns not to adjust past 26 inches from wheel center to fender edge — that measurement, not the key, is the real limit.
What is the biggest tire I can run on a leveled 2020+ 2500HD?
ReadyLIFT states a 35x12.50 maximum on its 2-inch leveling kit, on a 20x9 wheel at +18 or 0 offset, and warns that trimming may be required with some tire styles at 0 offset. Rough Country's 3-inch 95830 also lists 35x12.50R20 on 20x9 wheels with no trimming noted. Two cautions straight from the makers: Silverado and Sierra fender openings are not identical, and the one bigger number in this guide — Cognito's 37x12.50 — applies only to the ZR2 and AT4X kit, not to a standard leveled truck.
Will a 2011–2019 kit fit a 2020 or newer HD truck?
No. The kit makers treat 2011–2019 and 2020+ as separate fitment families even though both use torsion-bar front suspension. ReadyLIFT sells the 66-3011 for the earlier trucks and the 66-30200 for 2020+, and the newer kit is built around the current platform's OE torsion key part numbers. Order by generation, not just by model name — a Silverado 2500HD badge spans both families.
