Overview
The RE1455 is an Extreme-Duty rear leaf spring with a 4.5-inch lift for the 1987–1995 Jeep Wrangler (YJ). It is designed for maximum articulation, a smooth ride, increased load capacity and durability, and it handles the extra torque from larger tires and lower gears.
The spring works within a lift height range of 0 to 4.99 inches and is sold individually. Bushings are not included.
Key features
- Military wrap spring eyes
- Diamond cut leaves
- Bolt-on spring clamps
- Antifriction sliders
- Top grade US steel.
- Maximum articulation and load capacity for larger tires and lower gears
Rear suspension setup
Changing a rear leaf spring affects the whole rear suspension. A taller spring changes the angle of the shock and the driveline, so the shocks should be checked for proper length and travel. Bump stops, brake lines and the vent hose should be checked as well, since the axle sits in a different position.
Spring rate and load capacity matter as much as lift. A stronger spring suits heavier tires and gearing, but it can ride firmly when the vehicle is light. Pairing the spring with fresh shocks and bushings sized for the new setup helps the rear end ride and track as intended. Look for sagging, cracked leaves and loose clamps as signs a spring has worn.
- Check shock length and travel
- Inspect bump stops and brake lines
- Replace bushings along with the spring

Vehicle fitment
It is a direct fit for the 1987–1995 Jeep Wrangler (YJ) in the 0 to 4.99 inch lift range.
It is for the YJ chassis only. The later TJ (1997–2006) and the JK (2007–2018) are not covered. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Support the vehicle on jack stands before working underneath it. Replacing a rear leaf spring means supporting the axle and removing the old spring. A 4.5-inch lift changes driveline angles, so check the driveline and alignment after installation.
What’s included
One Extreme-Duty rear leaf spring. Springs are sold individually, so each side of the rear axle needs its own spring.
Not included: bushings.
