Description & Fitment
For the 2-door 2007-2018 Jeep Wrangler JK, this TeraFlex Coil Spring Base Lift Kit offers 2.5", 3" or 4" of lift with TeraFlex 9550 VSS Twin-Tube shocks, with shock extensions (2.5") or with no shocks. TeraFlex describes the 2.5" kit as an ultra-simple way to fit larger tires while keeping on-road handling. The 3" and 4" versions need longer preset or adjustable control arms and an adjustable front track bar to correct geometry, plus caster correction (not included), and TeraFlex recommends an adjustable rear track bar at 4". Wheels need 4.75" or less backspacing (or 1055000 adapters), driveshaft changes may be needed, and 2007-2011 JKs need extended front brake lines (4353300).

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.

Installation

Here's the short version. Follow TeraFlex's install sheet (below) for your Jeep's exact steps and torque values.
- Lift the Jeep by the frame, remove the wheels, support the front axle, loosen (do not remove) all control arm bolts, remove the exhaust skid plate/cross member (not reused), front driveline at the axle and sway bar links, free the ABS lines and breather tube, then lower the axle and remove the springs.
- Fit the new front springs driver side first, rotating each until fully seated, and add the speedbumps or bump stop extensions your kit includes per their TeraFlex instructions.
- Install the front shocks (top nut 20 ft-lbs, lower bolt loose for the brake line anchor), the quick disconnect sway bar links (75 ft-lbs), the kit's front control arms and track bar, then the brake line anchors and the front driveline with thread locker at 15 ft-lbs (p6-p7).
- Loosen the Y-pipe clamp, chisel off the intermediate pipe's indexing stop, and fit the exhaust flange spacers (longer one on the passenger side) with the supplied bolts, checking alignment and clearance.
- Rear: support the axle, remove the shocks, track bar, sway bar links and driveline at the axle, free the breather and ABS lines, then fit the springs and upper and lower spring retainers (30 ft-lbs and 50 ft-lbs, p10), the kit's rear arms, the track bar bracket on its U-bolts (p11), bump stops and sway bar links at 75 ft-lbs (p12).
- With the Jeep at ride height torque all suspension and track bar bolts, check every component, center the steering with the drag link, and re-torque after the first 500 miles and every 3,000.
