Jeep TJ lift kits run from a $100 to $250 spacer boost to $300 to $900 for a 2 to 3.5 inch coil spring kit, and $2,000 to $4,500 for a 4-inch long arm system. A 3.5 to 4 inch lift fits 33-inch tires on a 1997-2006 Jeep Wrangler TJ, and 35s need extra work.
Key takeaways
- The 1997-2006 Jeep Wrangler TJ uses coil springs at all four corners, so most lifts swap springs, shocks and control arms rather than adding blocks.
- Any TJ lift over about 2 to 3 inches usually needs a slip yoke eliminator (SYE) and a CV rear driveshaft on NP231 transfer cases to stop driveline vibration.
- A 3.5 to 4 inch lift clears 33×12.50 tires, and 35s generally need a 1-inch body lift or fender trimming plus 4.56 or 4.88 gears.
- Rubicon Express rated its 3.5-inch Super-Flex TJ kit for 33×12.5 tires without a body lift and 35×12.5 with a 1-inch body lift.
- TJ frames rust at the rear control arm mounts, so inspect them before you spend money on a lift.

This page covers how TJ suspension works, which lift height fits your use, what tires go with each height, what breaks, which brands to buy, cost and the install. It also covers the 2004-2006 Wrangler Unlimited (LJ), which uses the same parts with longer rear arms and springs.
How is the Jeep TJ suspension built?
The Jeep Wrangler TJ rides on solid axles front and rear, each located by upper and lower control arms and a track bar, with coil springs at every corner. A Dana 30 front axle is standard. Most trucks have a Dana 35 rear, while Rubicons and some Sports got the stronger Dana 44.
Because the TJ uses coils, lift kits are simple to understand. Taller springs raise the Jeep, longer shocks keep the travel usable, and adjustable arms fix the axle angle and pinion angle that change as the Jeep rises. A track bar is the diagonal bar that keeps the axle centered under the body.
How much lift should you put on a Jeep TJ?
A Jeep TJ that drives on the road most days works best with 2 to 3.5 inches of lift. That range fits 31 to 33 inch tires without changing the driveline much. A 4-inch lift is the practical ceiling for a short arm kit, and anything above that belongs on a long arm system.
For a daily-driven TJ, a 2.5 to 3 inch spring and shock kit with adjustable front lower arms is the better choice because it clears 32s, keeps the stock driveshaft on many Jeeps, and costs under $1,500 installed. Save long arms for Jeeps that spend real time on rocks.
| Lift type | Lift height | Typical parts | Realistic max tire | Parts price | Shop labor |
|---|---|---|---|---|---|
| Spacer boost | 1.75-2 in. | Coil spacers, shock extensions | 31 in. | $100-$250 | 3-4 hrs |
| Spring and shock kit | 2-3 in. | Coils, shocks, brake lines | 32 in. | $300-$900 | 4-6 hrs |
| Short arm kit | 3.5-4 in. | Coils, shocks, adjustable arms, track bar | 33 in. | $800-$1,800 | 8-10 hrs |
| Long arm kit | 4-4.5 in. | Frame brackets, long arms, coils, shocks | 35 in. | $2,000-$4,500 | 14-20 hrs |
Short arm or long arm for a TJ?
A short arm kit keeps the factory control arm mounting points, while a long arm kit moves the front mounts back to a new frame bracket or skid. Long arms give a smoother ride and more articulation at 4 inches and up. They also cost two to three times as much and require cutting off factory brackets.
What size tires fit a lifted Jeep TJ?
A 3.5 to 4 inch lift fits 33×12.50R15 or 285/75R16 tires on a Jeep Wrangler TJ. Stock tires on most TJs measure about 29 to 31 inches. A 2-inch lift clears 31s, and a 2.5 to 3 inch lift clears 32s.
Thirty-five inch tires need a 4-inch lift plus either a 1-inch body lift or trimmed fenders, and you should plan on high-clearance flares. According to Rubicon Express’s 3.5-inch Super-Flex fitment notes, its TJ kit cleared 33×12.5 tires without a body lift and 35×12.5 tires with a 1-inch body lift. Our body lift vs suspension lift guide explains when a small body lift helps.
Bigger tires need lower gears. Most TJs came with 3.07, 3.73 or 4.10 gears, and 33s drive best with 4.56 gears while 35s want 4.88s. A Dana 35 rear is a weak point behind 35s, so many owners upgrade the axle at the same time.
What breaks or needs changing when you lift a TJ?
A lifted Jeep TJ puts new angles on the driveline and new loads on 20-plus year old parts. Check these before and after the install:
- Rear driveshaft. Lifts over about 2 to 3 inches cause vibration on the NP231 slip yoke transfer case. An SYE kit with a CV driveshaft fixes it and adds $500 to $900.
- Frame rust. Rear lower control arm mounts on TJ frames rust through. Replace or plate them before lifting.
- Track bar and steering. A lift shifts the axle sideways. An adjustable front track bar re-centers it and reduces the chance of death wobble, a violent front-end shake at highway speed.
- Brake lines. Stock lines run tight at full droop above 2 inches. Most kits include extended lines.
- Caster. Lifting rotates the front axle and reduces caster. Adjustable lower arms bring it back.
Safety note: A TJ lift changes steering geometry, brake line slack and axle location. Get a professional alignment the same day and retorque the arm bolts at ride height.
Which Jeep TJ lift kits are worth buying?
The right Jeep TJ lift kit brand depends on budget and how hard you wheel. The brands below all build complete TJ kits, and prices are typical 2026 street prices that move with shock choice.
| Brand and kit | Lift height | Price range | What’s included | Best for | Not good for |
|---|---|---|---|---|---|
| Rough Country | 2.5-4 in. | $250-$900 | Coils, shocks, some arm options | Tight budgets, mild trails | Hard rock crawling |
| TeraFlex | 2.5-4 in. | $700-$2,000 | Coils, shocks, bump stops, arms on higher kits | Balanced street and trail | Buyers under $700 |
| Old Man Emu (ARB) | 2-2.5 in. | $900-$1,400 | Coils, OME shocks | Ride quality, overlanding | 35-inch tires |
| Rubicon Express | 3.5-4.5 in. | $900-$3,500 | Coils, arms, track bar, long arm option | Flex and articulation | Low-budget builds |
| Currie / Metalcloak | 3-4.5 in. | $1,800-$4,500 | Premium arms and joints | Serious rock crawlers | Daily drivers on a budget |
Rough Country wins on price. TeraFlex and Rubicon Express give better parts and more tuning. Currie and Metalcloak are overkill for a Jeep that sees fire roads twice a year.
How much does a Jeep TJ lift cost installed?
A Jeep TJ lift costs $700 to $1,500 installed for a 2 to 3 inch spring kit, $1,800 to $3,500 for a 3.5 to 4 inch short arm kit with an SYE, and $4,000 to $7,000 for a long arm system. Labor runs $100 to $175 per hour, based on typical US shop labor rates in 2026.

How do you install a coil spring lift on a Jeep TJ?
A 2 to 3 inch spring and shock lift on a Jeep TJ takes one person about 5 to 6 hours in a driveway with jack stands, a floor jack and a torque wrench. Follow your kit’s instructions and torque chart.
- Park on level ground, measure fender height at all four corners, and soak every bolt with penetrating oil the night before.
- Raise the front by the frame, set jack stands, and remove the wheels.
- Disconnect the sway bar links, track bar at the axle, and lower shock bolts.
- Lower the axle slowly on a floor jack until the coils come out.
- Install the new coils, bump stop extensions and shocks, then raise the axle.
- Replace the front brake lines if the kit includes them, and bleed the brakes.
- Repeat at the rear axle.
- Reinstall the track bars and sway bar links, torque arm bolts at ride height, and get an alignment.
Safety note: Brake line changes require a full brake bleed before driving. Test the pedal before leaving the driveway.
Frequently asked questions
Do I need a slip yoke eliminator for a TJ lift?
Yes, for most lifts over about 3 inches. The NP231 transfer case on non-Rubicon TJs uses a slip yoke that creates a steep driveshaft angle when lifted, which causes vibration. An SYE kit and CV driveshaft cost $500 to $900. Rubicons with the NP241OR usually need only a new driveshaft.
What is the biggest tire on a TJ with a 4 inch lift?
33-inch tires fit without cutting. A 4-inch lift on a Jeep Wrangler TJ clears 33×12.50 tires on 15-inch wheels with correct backspacing. Thirty-five inch tires need a 1-inch body lift or fender trimming, high-clearance flares and a regear to 4.88. A Dana 35 rear is weak behind 35s.
Will a TJ lift kit fit a Jeep LJ Unlimited?
Mostly yes. The 2004-2006 Wrangler Unlimited (LJ) shares front parts with the TJ, but it has a longer wheelbase, longer rear control arms and different rear springs. Buy the LJ-specific version of the kit, because TJ rear springs and arms will leave the LJ sitting wrong.
Does a lift cause death wobble on a TJ?
No, not by itself. Death wobble on a TJ usually comes from a worn track bar, loose track bar bolts, worn ball joints or tie rod ends, or low caster after a lift. An adjustable track bar and correct caster prevent it. Check and torque the track bar bolts after the first 100 miles.
Can you put a 4 inch lift on a TJ yourself?
Yes, if you have basic tools and patience. A short arm 4-inch kit takes 8 to 10 hours for a first-timer and often needs drilling. Plan on soaking rusted arm bolts, bleeding brakes, and paying a shop $100 to $200 for an alignment after the install.
The bottom line
The best Jeep TJ lift kits for most owners deliver 2.5 to 3.5 inches with quality coils, shocks and an adjustable track bar on 32 or 33 inch tires. Go bigger only when you are ready to pay for an SYE, gears and a stronger rear axle.
