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
Does this fit a 2-door JK?
No. The 2-door version is part 1223000.
Will my stock wheels work?
Only with TeraFlex's 1055000 offset wheel adapters. Otherwise use wheels with 4.75" backspacing or less.
What else should I budget for?
Shocks and an alignment. Cutting is required, 2007-2011 models need TeraFlex's 26" front brake line kit (4353310), and some Jeeps need driveshaft upgrades.
What warranty does TeraFlex give?
TeraFlex covers its control arms, IR bushings, coil springs, bump stops and track bars for life against defects in materials and workmanship. Non-IR control arm and track bar bushings carry 1 year and finishes 90 days. For a claim, contact us with your order details.
How quickly does it ship?
Shipping is free to the lower 48 states, and most orders arrive within 1-5 business days. We email your tracking number as soon as it ships.
Can you confirm it's right for my Jeep before I order?
Yes. Contact us with your VIN or year, model and trim, plus your current lift, and we'll check it against TeraFlex's fitment information before it ships.
Installation
- 1/4" and 1/2" ratchets

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.
