Overview
The Rubicon Express RE6300M is a 5.5-inch Extreme-Duty long arm lift kit with monotube shocks for the 1984–2001 Jeep Cherokee XJ. It is a direct fit for the Base, Briarwood, Chief, Classic, Country, Laredo, Limited, Pioneer, SE and Sport trims.
The kit is a complete suspension replacement with longer control arms, which improves lifted suspension geometry. The longer arms add stability on and off road, less torque roll and axle steer, and better traction than short arm lift kits.
The kit includes a three-piece crossmember, front Extreme-Duty radius long arms with Super-Flex spherical ball joints, a heavy-duty track bar, a track bar bracket brace and Gen II disconnects. The specifications list a 33-inch tire size, a lift height range of 4 to 5.5 inches and shocks as included.
Key features
- Monotube shocks, per the title
- Three-piece crossmember for transfer case and transmission access
- Front Extreme-Duty radius long arms
- Serviceable Super-Flex spherical ball joints
- Heavy-duty track bar, bracket brace and Gen II disconnects
Choosing monotube shocks
Monotube shocks use a single tube with a floating piston, which helps them resist heat buildup during long grades. They suit trucks that run on rough ground for long periods, and they can be easier to tune than twin tube designs. Shock selection should follow the lift height, the tire size and how the truck is used.
A long arm kit with new shocks should have the shock length checked before installation, because the ride height moves. Leaf spring rear suspensions also work with the shock mounts, so inspect the mounts and bushings during the install. Keep the old shock hardware if it is in good shape, since a matched set simplifies the work.
- Confirm shock length against the new ride height
- Inspect shock mounts for cracks
- Replace worn bushings alongside the shocks
