Overview
This Fox 985-24-131 is a rear 2.0 PS Smooth IFP shock sold individually. It fits the 1986–1992 Jeep Comanche and the 1993–1998 and 1999–2004 Jeep Grand Cherokee (ZJ and WJ), and it is designed for a 2 to 4 inch lift range.
Its IFP design keeps the damping oil separated from the nitrogen gas charge. The extended length is 26.35 and the collapsed length is 16.75, with a travel of 9.6, all given without a unit.
Key features
- Rear mounting position for the listed Jeep models
- Internal floating piston separating oil from nitrogen gas
- Direct fit with a stated 2 to 4 in. lift range
- Feature line gives a narrower 2 to 3 inch range
- Travel of 9.6, extended 26.35, collapsed 16.75
Choosing shock length and lift
A rear shock controls how the axle and body move over bumps, and on a lifted Jeep it carries more of the load as the suspension rises. An internal floating piston keeps the damping oil separate from the nitrogen charge, which helps damping stay steadier during long descents and repeated trail hits.
Before buying a replacement, measure the installed lift and compare it with the shock’s rated range, because height decides how much travel the shock uses. Compare the extended and collapsed lengths with the shock being removed, and check that the mounting eyes match your existing hardware. Worn bushings and bent brackets are often replaced at the same time.
- Measure installed lift before choosing a length
- Compare mounting eye sizes with the removed shock
- Inspect rear shock bushings for cracking
- Look for oil seepage around the shaft
