Description
Product Overview
The iFJF Adjustable Front Coil Spacer Kit delivers the most versatile lift solution for TJ, LJ, XJ, ZJ, and MJ owners who need precise ride height control. CNC-machined from solid billet aluminum, this threaded collar system lets you dial in your front lift from zero to 3.75 inches without removing the coil springs. On-vehicle adjustability means fine-tuning ride height for a level stance or compensating for different bumper/winch weights takes minutes — not hours.
Key Features
-
Infinitely Adjustable 0-3.75" Lift — Threaded billet aluminum collar design allows micro-adjustments without disassembling suspension. Dial in the exact height you need.
-
No Spring Compressor Required — Unlike traditional spacers, this collar mounts externally and adjusts with basic hand tools. No spring removal, no compressor.
-
CNC Billet Aluminum Construction — Machined from solid 6061-T6 aluminum. Won't deform under heavy load like plastic or rubber spacers. Anti-corrosion, anti-rust.
-
Isolator Pad Included — Integrated polyurethane isolator prevents metal-on-metal contact and eliminates suspension noise. Anti-slip grip ring keeps everything locked.
-
Multi-Platform Coverage — Fits Wrangler TJ (1997-2006), LJ Unlimited (2004-2006), Cherokee XJ (1984-2001), Grand Cherokee ZJ (1993-1998), and Comanche MJ (1986-1992).

Frequently Asked Questions
Q: Can I adjust height without removing the springs?
A: Yes — that's the core advantage. Loosen set screws, spin the collar, re-torque. No spring compressor needed, no spring removal.
Q: What's the max safe lift with stock control arms?
A: Stay at 1.5" or below with factory arms. Going higher without adjustable control arms reduces caster and causes wandering steering. For 2-3.75", adjustable arms are strongly recommended.
Q: Will this fix my sagging driver-side lean?
A: Absolutely. Set the driver side collar slightly higher to compensate for years of single-occupant weight and spring fatigue.
Q: Does this work on rear coil springs?
A: No — designed for front coil springs only. Rear coil spring diameter and mount design differ on these platforms.
Q: Fixed spacer vs adjustable collar — what's the real difference?
A: Fixed spacers = one height, spring removal required. Our adjustable collar = infinite height control, on-vehicle adjustment, no spring removal ever.
