Best Lift Kits for Jeep Gladiator

The short answer: the Gladiator sorts its owners into three briefs. For 35s and factory manners, the Mopar 2-inch Jeep Performance Parts kit is the engineered answer. For 37s on a Rubicon, two verified routes exist — ReadyLIFT’s spacer SST at the cheap end and its 4-inch Terrain Flex system at the serious end, with Rough Country’s 3.5-inch kit between them. For a level stance on a budget, TeraFlex’s 1.5-inch spacer kit is the budget pick, and honest about what it is. And if you own a Mojave, almost everything in this guide excludes your truck — read the buying guide section first. All five picks were verified on manufacturer pages or dealer listings reproducing manufacturer data, checked 2026-11-04, and every pick is sold on Amazon — this guide only features products with a verified Amazon listing, so the listing images and details are the real ones. We have not hands-on tested them, and our method is in how we test and verify. Platform background lives in the Gladiator hub.

Mopar 2-Inch Lift Kit — Jeep Performance Parts (77072468AG)

MCheck Price on AmazonSource listing used for verification

Last checked November 4, 2026

Key specs

• Front lift: 2″
• Rear lift: 2″
• Type: suspension lift
• Max tire stated: 35″
• SKU: 77072468AG

Why we recommend it

Jeep's own kit is the factory-engineered route: 2 inches of lift, longer front control arms to keep geometry honest, and shocks included. One honesty note, because the box contents have changed under a single part-number family: earlier revisions shipped FOX 2.5-inch monotube shocks and fit 2020–2023 trucks only, while the current AG revision ships Bilstein reservoir shocks and fits through 2026 — Quadratec's listing spells out the split, and Mopar's eStore copy still describes the FOX build. Confirm which revision you are buying. On tire size, Quadratec's spec table for the kit lists a 35-inch maximum; Mopar's own description promises only 'larger tires' without a number, so 35 is a dealer-spec figure, not a Mopar-published one. It is priced like the factory part it is, and it was out of stock at the eStore on our check date.

Best for: Daily-driven Gladiators that will run 35s and keep factory manners

Pros

• ✓ Factory-engineered for the JT, sold through Mopar
• ✓ Shocks and longer front control arms included
• ✓ No driveshaft or brake-line replacements required, per Mopar

Cons

• ✗ Priced like a factory part, and out of stock at the Mopar eStore on our check date
• ✗ The 35-inch tire figure comes from a dealer spec table, not Mopar's own copy
• ✗ Excludes Mojave; EcoDiesel uses a different part number (77072469)

ReadyLIFT

ReadyLIFT 2.5-Inch SST Lift Kit (69-6025)

Check Price on AmazonSource listing used for verification

Last checked November 4, 2026

Key specs

• Front lift: 2.5″
• Rear lift: 2″
• Type: suspension lift
• Max tire stated: 37″
• SKU: 69-6025

Why we recommend it

The SST is the spacer alternative to a full system: 2.5 inches front, 2 rear, factory springs and shocks retained, so the ride you have is the ride you keep. ReadyLIFT states the same trim split as its 4-inch system — 37x12.50 on Rubicon, 35 inches on Sport and Overland — which makes this the cheapest verified route to a manufacturer-stated 37 on a Rubicon. Our record rests on dealer listings reproducing ReadyLIFT's data, because ReadyLIFT's own product page would not load; that sourcing is disclosed in the kit record.

Best for: Rubicon owners who want 37s without replacing springs and shocks

Pros

• ✓ Lowest-priced verified route to a stated 37x12.50 fitment (Rubicon)
• ✓ Retains factory springs and shocks, so ride quality stays stock
• ✓ Lifts front and rear, not just a front level

Cons

• ✗ A spacer kit adds no suspension travel
• ✗ Excludes the Mojave
• ✗ Verified via dealer listings; ReadyLIFT's own page did not load for this kit

Rough Country

Rough Country 3.5-Inch Lift Kit (64930)

Check Price on AmazonSource listing used for verification

Last checked November 4, 2026

Key specs

• Front lift: 3.5″
• Type: suspension lift
• Max tire stated: 37″

Why we recommend it

Rough Country's 3.5-inch kit is the value pick with real hardware — dual-rate coil springs and a forged adjustable track bar — and it states clearance for up to 37-inch tires. Read the configuration ladder before comparing prices: the starting build is the shock-extension configuration in dealer option tables, and the N3, V2, M1 and M1R shock builds cost more. This record covers the 2020–2023 application; a separate 2024+ application exists.

Best for: Budget-conscious owners who want spring-lift hardware, not just spacers

Pros

• ✓ Coil springs and a forged track bar at a spacer-kit price
• ✓ States clearance for up to 37-inch tires
• ✓ Configurable shock options to match budget and use

Cons

• ✗ The starting price is the shock-extension build; shock builds cost more
• ✗ Excludes EcoDiesel (spring rates are tuned to engine weight)
• ✗ Excludes Mojave — its shocks do not fit the Mojave's larger shock bolt

ReadyLIFT

ReadyLIFT 4-Inch Terrain Flex Lift Kit (69-6041)

RCheck Price on AmazonSource listing used for verification

Last checked November 4, 2026

Key specs

• Front lift: 4″
• Rear lift: 3″
• Type: suspension lift
• Max tire stated: 37″
• SKU: 69-6041

Why we recommend it

The Terrain Flex is the Gladiator's geometry-complete archetype: 4 inches front, 3 rear, replacement front springs with a heavier wire diameter for winch-and-bumper weight, heavy-duty lower control arms for caster correction, an adjustable front track bar, and Falcon 2.1 monotube shocks tuned for the JT. ReadyLIFT's stated ceilings are 37x12.50 on Rubicon and 35 inches on Sport/Overland. It is the most expensive kit here, and the specification is why. Two conditions ride along: ReadyLIFT recommends an aftermarket CV-style front driveshaft under heavy off-road use, and trucks with adaptive cruise control need a dealer zero-point calibration after installation.

Best for: Built Rubicon rigs running 37s with winch and bumper weight

Pros

• ✓ Geometry-complete: springs, control arms, track bar and Falcon shocks
• ✓ Heavier front springs rated for winch and bumper weight
• ✓ 37x12.50 stated on Rubicon, the joint-highest claim in this guide

Cons

• ✗ Most expensive kit in this guide
• ✗ CV-style front driveshaft recommended for heavy off-road use
• ✗ Excludes diesel and Mojave; adaptive-cruise trucks need a dealer calibration

TeraFlex

TeraFlex 1.5-Inch Performance Spacer Leveling Kit (1155300)

Check Price on AmazonSource listing used for verification

Last checked November 4, 2026

Key specs

• Front lift: 1.5″
• Rear lift: 0″
• Type: leveling
• Max tire stated: 33″
• SKU: 1155300

Why we recommend it

TeraFlex's front-only leveling kit is the cheapest verified part in this guide: stacked 1-inch and 0.5-inch front spacers plus bump stop extensions, working with your stock-length shocks. Its stated max tires — 33 inches on Sport/Overland fenders, 35 on Rubicon fenders, both at stock wheel backspacing — make it a genuine tire-clearance buy, not just a stance fix, and TeraFlex positions it as compensation for bumper, winch and gear weight as much as lift. The fine print is real: wheels with less backspacing than stock require rear bump stop strike pad extensions that are not in the box, and plastic-bumper trucks must remove the bumper-to-fender deflectors to fit 35s.

Best for: Owners who only want the factory rake gone, or room for a Rubicon 35

Pros

• ✓ Cheapest verified kit in this guide
• ✓ Stated 35-inch clearance on Rubicon fenders
• ✓ Also compensates for bumper, winch and gear weight sag

Cons

• ✗ Front only — no rear lift and no added travel
• ✗ No shocks included; it works with stock-length units
• ✗ Low-backspacing wheels need extra bump-stop parts not in the box

Buying Guide: How to Choose a Gladiator Lift Kit

Start with the Mojave question. The Mojave is the Gladiator’s factory-lifted trim, and it is a genuine platform split, not a badge: FOX 2.5-inch internal-bypass shocks with external reservoirs, hydraulic jounce bumpers, and shock hardware that standard JT kits do not match. The evidence is consistent across every manufacturer in this guide — Mopar states its kit “will not work for a Mojave JT”, Rough Country cannot fit its shocks to the Mojave’s larger shock bolt, and ReadyLIFT and BDS exclude the trim by name. ReadyLIFT does build the exception: the 69-6043 Terrain Flex Max, a 4-inch kit engineered specifically for the Mojave that retains the factory FOX shocks and jounce bumpers via new shock mount extensions, and states up to a 37-inch tire. We verified it in dealer listings reproducing ReadyLIFT’s copy rather than on ReadyLIFT’s own page, so it is named here rather than given a kit record — but if you own a Mojave, it is the part number to start from, and every pick above is the wrong shelf.

Then the engine. Diesel and gasoline Gladiators run different spring rates, and the catalogue enforces it: the Mopar kit in this guide is the 3.6L gasoline application (the EcoDiesel’s is part number 77072469), and the aftermarket kits above enforce the same split. A listing that does not name your engine has not answered the fitment question.

Then your tire goal, by trim. The Rubicon’s high-clearance fenders change the math: ReadyLIFT states 37x12.50 for a Rubicon on both its 2.5-inch SST and its 4-inch Terrain Flex, while Sport and Overland trucks are stated at 35 inches on the same kits, and BDS states 35 as its platform maximum. Treat the trim split as the rule, not the headline.

Finally, the type of lift. A spacer kit (TeraFlex, ReadyLIFT SST) lifts the body of the suspension without adding travel — cheap, honest, and ride-preserving. A spring-and-shock system (BDS, Rough Country’s shock builds, the Mopar kit) replaces the working parts. A complete system (Terrain Flex) adds the correction hardware — control arms, track bar — that keeps geometry right at height. Leveling kit vs lift kit vs body lift explains why a budget spacer kit and the premium Terrain Flex are both honestly called lifts while doing completely different jobs.

What we left out, and why

BDS’s 3-inch system was a pick in this guide’s first edition, and its manufacturer data is verified — it is carried on the Gladiator hub. It is not a pick here because BDS sells through its dealer network and we could not verify an Amazon listing for any of its configurations; this guide only features products sold on Amazon, so we can show the real listing for everything we recommend.

ICON Vehicle Dynamics, MetalCloak and Clayton Off Road all sell Gladiator systems, and AEV sells a spacer kit Gladiator owners ask about. Their absence is a verification statement, not a quality judgement: the picks above are the kits we verified to the standard our records require — a named SKU, an application scope, an exclusion list and a checkable application — and those brands were not verified to that standard in this pass. FOX appears in this guide the way it appears in the Gladiator market: as the damper inside other brands’ kits (Mopar’s earlier revisions, BDS’s shock options, the Mojave’s factory suspension), not as a standalone JT lift kit. If a later pass verifies the missing brands properly, they will be added.

🏆 Our Top Recommendation

Mopar 2-Inch Lift Kit — Jeep Performance Parts (77072468AG)

M

If you want one recommendation: buy the kit Jeep engineered for the truck. The Mopar 2-inch kit is the only pick here designed by the same people who built the Gladiator — control arms for correct geometry, shocks in the box, and no driveshaft or brake-line changes required. For the most common Gladiator brief — 35-inch tires and factory road manners — it is the answer with the fewest asterisks.

Jeep's own kit is the factory-engineered route: 2 inches of lift, longer front control arms to keep geometry honest, and shocks included. One honesty note, because the box contents have changed under a single part-number family: earlier revisions shipped FOX 2.5-inch monotube shocks and fit 2020–2023 trucks only, while the current AG revision ships Bilstein reservoir shocks and fits through 2026 — Quadratec's listing spells out the split, and Mopar's eStore copy still describes the FOX build. Confirm which revision you are buying. On tire size, Quadratec's spec table for the kit lists a 35-inch maximum; Mopar's own description promises only 'larger tires' without a number, so 35 is a dealer-spec figure, not a Mopar-published one. It is priced like the factory part it is, and it was out of stock at the eStore on our check date.

Final Thoughts

Confirm trim and engine against the part number before you order — on this platform the Mojave question comes first, then diesel versus gasoline, then the Rubicon tire split. Then run the numbers end-to-end: the tire size calculator for your target size, the tire size and lift height guide for the general rules, and how much does it cost to lift a truck for installed cost including the alignment every one of these kits requires.
