Best Leveling & Lift Kits for Ram 2500

The Ram 2500 changed its rear suspension in 2014 — a segment-exclusive five-link coil rear suspension replaced leaf springs, with an optional rear air suspension on top of it (Ram’s own 2014 Heavy Duty press material announces both). That one engineering decision still organises the entire leveling catalogue: everything in this guide is built for the coil-rear truck, the air-rear truck is excluded almost everywhere, and the front end splits the catalogue again by engine, because a Cummins diesel and a Hemi gas V8 do not weigh the same over the front axle. Add the Power Wagon — the factory-lifted trim no mainstream kit will touch — and you have the three questions that decide a Ram 2500 purchase: coil or air at the rear, gas or diesel at the front, and is it a Power Wagon? Six kits were verified on manufacturer pages or dealer listings reproducing manufacturer data on the date shown, covering both generations (2014–2018 and the 2019+ redesign); the four sold on Amazon are the picks in this guide, and the other two are covered on the hub — see “What we left out” in the buying guide below. Platform background lives on the Ram 2500 hub.

How we chose these kits

Verified-spec comparison, as everywhere on this site: manufacturer page, lift height, stated max tire, exclusions in the manufacturer’s words. Our method is in how we test and verify; we have not installed or hands-on tested any of these kits. Scope note: several of these kits also fit the Ram 3500 — this guide records the 2500 application, and the per-kit exclusions state the rest.

Rough Country

Rough Country 2.5-Inch Leveling Kit (377)

Check Price on AmazonSource listing used for verification

Last checked November 4, 2026

Key specs

• Front lift: 2.5″
• Rear lift: 0″
• Type: leveling
• Max tire stated: 35″
• SKU: 377

Why we recommend it

Rough Country's configurable 2.5-inch leveling kit — coil spring spacers for radius-arm trucks, 2014–2026, either engine. Its fitment notes are the platform's exclusion list in miniature: no Power Wagon, no Rebel (Rough Country's reasoning printed with it — a factory 1–2 inch lift), no rear air ride. Its wheel and tire table is equally honest: 35x12.50 is the ceiling, and the 20-inch fitment of it is flagged as requiring trimming. Optional shock upgrades complicate the order — they do not fit dually models, and the rear shock part numbers differ between leaf-spring and coil-spring rear trucks, so the configuration questions on the page are load-bearing.

Best for: Either-engine coil-rear trucks on a budget

Pros

• ✓ Covers 2014–2026, gas or diesel, on the factory springs
• ✓ Exclusions printed in miniature: Power Wagon, Rebel, rear air
• ✓ Configurable, with optional shock upgrades

Cons

• ✗ 35x12.50 on a 20-inch wheel requires trimming
• ✗ Shock upgrades do not fit dually models
• ✗ Rear shock part numbers differ by rear suspension — order carefully

ReadyLIFT

ReadyLIFT 1.75-Inch Leveling Kit (66-1113) — 2014–2018

Check Price on AmazonSource listing used for verification

Last checked November 4, 2026

Key specs

• Front lift: 1.8″
• Rear lift: 0″
• Type: leveling
• Max tire stated: 35″
• SKU: 66-1113

Why we recommend it

ReadyLIFT sells the same idea twice, once per generation — fabricated steel top-mount coil spacers at 1.75 inches. The 66-1113 covers the 2014–2018 truck (per the dealer listing reproducing ReadyLIFT's data; ReadyLIFT's current page for this legacy kit could not be fetched, and its published fitment guide corroborates the 1.75-inch lift and 35-inch tire). It carries ReadyLIFT's explicit exclusions — no Power Wagon, no Snow Prep/Ambulance Package, radius-arm trucks only — and a blunt instruction that shock extensions are not compatible with the truck and must not be used.

Best for: 2014–2018 coil-rear trucks that want the simple spacer

Pros

• ✓ Stated 35-inch maximum tire
• ✓ Explicit exclusions — Power Wagon and Snow Prep named
• ✓ The generation-correct spacer for the 2014–2018 truck

Cons

• ✗ Radius-arm trucks only
• ✗ Shock extensions must not be used, per ReadyLIFT
• ✗ Record is dealer-sourced — ReadyLIFT's own page for this legacy kit could not be fetched

ReadyLIFT 1.75-Inch Leveling Kit (66-19180) — 2019+

Check Price on AmazonSource listing used for verification

Last checked November 4, 2026

Key specs

• Front lift: 1.8″
• Rear lift: 0″
• Type: leveling
• Max tire stated: 35″
• SKU: 66-19180

Why we recommend it

ReadyLIFT's second spacer is the same idea for the newer truck: steel top-mount coil spacers at 1.75 inches for the 2019+ generation, with shock relocation brackets in the box. Because it reuses the factory springs it fits either engine, gas or diesel, and ReadyLIFT states a 35-inch maximum tire — 35x12.50 with no rub on a 9-inch wheel at +12 to 0 offset. Its Amazon listing carries the exclusions this platform keeps repeating: no Power Wagon, no Snow Prep/Ambulance Package, radius-arm trucks only. One honesty note from our data record: ReadyLIFT's own page for this kit does not publish the Power Wagon or rear-air exclusions in the copy we fetched — the exclusions above are the ones printed on the Amazon listing itself, so confirm your trim against them before ordering.

Best for: 2019+ coil-rear trucks that want the simple spacer

Pros

• ✓ The generation-correct spacer for the 2019+ truck
• ✓ Fits either engine — it reuses the factory springs
• ✓ Stated 35-inch maximum tire at the stated wheel spec

Cons

• ✗ 2019+ new body only — the 2014–2018 truck uses the 66-1113
• ✗ Radius-arm trucks only
• ✗ ReadyLIFT's own page does not repeat the listing's exclusions — check the listing

Carli Suspension

Carli Suspension 2.5-Inch Leveling System (CS-DLVL) — Diesel

Check Price on AmazonSource listing used for verification

Last checked November 4, 2026

Key specs

• Front lift: 2.5″
• Rear lift: 0″
• Type: leveling
• Max tire stated: 35″
• SKU: CS-DLVL-CS-1419-D

Why we recommend it

Carli's 2.5-inch leveling system, sold through its dealers, is the most complete answer here: linear-rate front coils tuned specifically for the diesel 2500, Carli-SPEC 2.0 IFP shocks valved for this platform — Carli's dealer documentation describes dozens of tuning revisions behind the valving — and a specification table that lists a 35 x 12.5 tire fitment across its Ram leveling systems. It covers both generations of diesel truck, and it keeps the platform's rules: diesel only (Hemi trucks and the Power Wagon have their own Carli systems), and it does not work with rear auto-level air suspension, for which Carli again sells a separate system. One installation reality from the dealer documentation: the front axle sits slightly pulled to the driver's side after the lift, which Carli's adjustable track bar corrects — budget for the geometry, not just the springs.

Best for: Diesel owners who want the tuned system, not just the height

Pros

• ✓ Coils and shocks tuned specifically for the diesel 2500
• ✓ Covers both generations (2014–2018 and 2019+)
• ✓ Stated 35 x 12.5 tire fitment

Cons

• ✗ Diesel only — Hemi trucks use different Carli systems
• ✗ Excludes rear auto-level air suspension and the Power Wagon
• ✗ Axle shift after the lift needs the adjustable track bar answer; premium money

Buying Guide: The Three Splits

Coil vs air at the rear. Since 2014 the standard Ram 2500 rear is a five-link coil design; the optional air suspension swaps the coils for bags and levels itself under load. A front leveling kit does not touch the rear springs — but an air truck sits level by design, which is why ReadyLIFT says installing its diesel kit on one will overlift the front, and why Rough Country, BDS and Carli simply exclude rear air ride trucks. Know which rear your truck has before you shop; the air system was an option across the range, not a trim.

The Power Wagon. Every mainstream manufacturer in this guide excludes it, by name, in the first lines of their fitment notes. It is not an oversight — the Power Wagon is factory-lifted for off-road use, and the kits here are engineered around standard-height trucks. Carli’s presence in this guide comes with the same boundary: its diesel leveling system is not a Power Wagon product; Carli builds the Power Wagon its own dedicated systems instead.

Gas vs diesel. Spacer kits do not care — they reuse your springs. Spring kits care completely: the two spring systems in this guide (ReadyLIFT’s 46-19121 and Carli’s leveling system) are diesel-only parts with separate Hemi equivalents sold under different part numbers. The engine question and the spacer-versus-spring question are the same question on this platform.

What we left out, and why

Two verified kits are not picks here, because this guide only features products sold on Amazon. ReadyLIFT’s 46-19121 (the 2019+ diesel spring-and-Falcon kit) stays fully documented on the Ram 2500 hub, but it has no Amazon listing we could verify to our standard. BDS’s 2-inch kit (BDS695) — spacers paired with real shocks — is dealer-sold, like every BDS system we have checked. Both still shape the splits above: the 46-19121’s air-suspension note is the clearest explanation of the coil-vs-air question on this platform.

🏆 Our Top Recommendation

Carli Suspension 2.5-Inch Leveling System (CS-DLVL) — Diesel

If you want one recommendation for a diesel Ram 2500, it is the Carli system: linear-rate coils tuned specifically for the Cummins truck, Carli-SPEC 2.0 IFP shocks valved for this platform, and a stated 35 x 12.5 fitment — the complete answer rather than the cheap one. The honest difference over a spacer is ride quality and tuning, not height.

Carli's 2.5-inch leveling system, sold through its dealers, is the most complete answer here: linear-rate front coils tuned specifically for the diesel 2500, Carli-SPEC 2.0 IFP shocks valved for this platform — Carli's dealer documentation describes dozens of tuning revisions behind the valving — and a specification table that lists a 35 x 12.5 tire fitment across its Ram leveling systems. It covers both generations of diesel truck, and it keeps the platform's rules: diesel only (Hemi trucks and the Power Wagon have their own Carli systems), and it does not work with rear auto-level air suspension, for which Carli again sells a separate system. One installation reality from the dealer documentation: the front axle sits slightly pulled to the driver's side after the lift, which Carli's adjustable track bar corrects — budget for the geometry, not just the springs.

Final Thoughts

Price the whole job — kit, labour, alignment — with how much does it cost to lift a truck, and if you are still deciding whether a level is even the right tool, leveling kit vs lift kit vs body lift comes before any of this.
