Description & Fitment
These TeraFlex 1.5" Lift Coil Springs are rated for the 2-door 2007-2018 Jeep Wrangler JK, sold as a front kit (1853022) or rear kit (1854022). TeraFlex tuned the rates and front-to-rear load bias for better highway handling and off-road performance, and uses linear-rate springs so the most coils stay active for predictable handling through the whole travel. TeraFlex counts the 1.5" as an average lift: a winch, bumpers, a full-size spare or cargo will change the final height.

About TeraFlex
TeraFlex describes itself as a Jeep company at heart, started and staffed by people who drive them. It designs, engineers and builds suspension systems, shocks, axles and performance parts, with the Wrangler and Gladiator at the center of the range.
The company traces its roots to the 1950s and MEPCO (Military Equipment Parts Company), an early supplier of Jeep parts. TeraFlex Manufacturing followed in 1996 to build heavy-duty suspension for the TJ Wrangler, and today's catalog runs from full lift systems and the Falcon shock line to axles, steering and armor.
Authorized TeraFlex dealer. Prestige Truck is an authorized TeraFlex dealer, so what we sell is new and genuine TeraFlex. In TeraFlex's words, its limited warranty extends "only to the consumer who originally purchased the product," so keep your receipt with your build records.
Frequently Asked Questions
Will these fit a JK Unlimited?
They are listed for the 2-door JK. For the 4-door, see 1853052 (1.5" on a 4-door) or the 1853102 group.
Do I need both kits?
For a lift front and rear, yes: 1853022 is the front kit and 1854022 the rear.
Is 1.5" exact?
TeraFlex says it is an average; accessories and cargo affect final height.

Installation
Here's the short version. Follow TeraFlex's install sheet (below) for your Jeep's exact steps and torque values.
- Raise and support the Jeep at the factory lift points, remove the wheels and support the axle with a jack or jack stands.
- Disconnect the sway bar links at the axle (18mm), the shocks at the axle (18mm) and the track bar at the axle (21mm, flag nut), and loosen, but do not remove, all front control arm bolts (21mm).
- Lower the jack until the springs are free and remove them, watching that the ABS lines, brake lines and breathers are not overstretched.
- Install both new coil springs, driver side first, rotating each until it is fully seated, then raise the jack to refit the shocks at 56 ft-lbs and the sway bar links at 75 ft-lbs.
- Refit the wheels (lug nuts 95-115 ft-lbs), lower the Jeep and on the ground torque the front track bar to 125 ft-lbs, the upper control arm bolts to 75 ft-lbs and the lowers to 125 ft-lbs.
- Center the steering wheel by turning the drag link adjuster sleeve (about 3/4 turn counter-clockwise from the driver side, then test drive), torque the pinch clamp bolts to 45 ft-lbs, and re-torque all bolts after 100 miles.
