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
What's the difference from 1335000?
1335000 is the complete kit for both axles. 1335200 is the front kit and 1335300 the rear kit.
Do I need special axles?
Yes. TeraFlex designed the system for 70" wide axles with 3.25" tubes, such as the Tera60.
What does install involve?
Cutting off the factory control arm brackets and spring buckets, welding, wheels with 4.75" backspacing or less (or two TeraFlex 1.75" wheel offset adapter pairs, 1057000), a front double cardan driveline upgrade for the added travel, inner wheel well and frame trimming, and an alignment.
What warranty does TeraFlex give?
TeraFlex's policy lists Falcon products, these coilovers included, at 1 year, and finishes at 90 days against defects; its list names no separate term for the mounting brackets. Some Falcon guides state longer, so contact us to confirm coverage or start a claim.
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 the right part before I order?
Yes. Contact us with your VIN or year, model and trim and what's on the Jeep now, and we'll check it against TeraFlex's fitment information before it ships.

Warranty
TeraFlex's warranty policy lists all Falcon products at 1 year, which covers the Falcon coilovers in this system; some Falcon quick-start guides state a longer term, so contact us to confirm the current Falcon coverage before you rely on it. TeraFlex's warranty list names no separate term for the coilover mounting brackets, so contact us and we will confirm that too. Finishes carry 90 days (defects only).- TeraFlex extends its limited warranty only to the consumer who first bought the product, and only on the vehicle the part was first installed on. It does not pass to a later owner.
- Coverage starts on the purchase date and does not restart if a part is repaired or replaced.
- For a covered defect, TeraFlex will either repair or replace the product (or the faulty part) free of charge or refund the purchase price, at its discretion, and it pays the freight to send a repaired or replacement part back to you.
- Not covered: damage from transportation, storage, improper use, skipped instructions or preventive maintenance, modifications, unauthorized repair, normal wear and tear, product finish, improper installation or maintenance, racing or competition, or accidents, abuse and neglect. Improper installation, poor maintenance, racing or competition use, and neglect or abuse void the warranty.
