FAQ
What is the RD09083FCD?The RD09083FCD is a Rock Krawler 2.625 inch remote reservoir rear shock built for 2018 and newer Jeep Wrangler JL and JLU models, featuring a Fast CD external compression adjuster for quick on the fly damping changes.
Does it fit a two door Wrangler JL?Yes, this shock fits both the two door JL and four door JLU since the rear shock mounting points are shared across the platform.
What does Fast CD adjustment mean?Fast CD stands for Fast Compression Damping, an external adjuster that lets you increase compression dampening by up to 30 percent without removing the shock or opening the body.
Can this shock be rebuilt or revalved?Yes, the shock uses a serviceable design so it can be rebuilt, resealed, or revalved by a qualified suspension shop as needed over its service life.
Is this shock compatible with a 2.5 inch lift?Yes, the RD09083FCD is specifically sized for 2.5 inch lift applications on the JL and JLU rear suspension.
Do I need a specific bracket to install it?Mounting hardware and brackets are included with the shock, so no separate bracket kit purchase is necessary for a standard installation.
What warranty comes with this shock?Rock Krawler backs this shock with a 6 month warranty against defects in materials and workmanship from the date of purchase.
Will this shock work with factory Jeep JL springs?It is designed as part of a lift application and is best paired with matching Rock Krawler springs or a compatible lift kit rather than factory springs.
How does the reservoir stay pressurized?The 3.25 inch remote reservoir uses an internal floating piston charged with argon gas to maintain consistent pressure and prevent oil aeration during hard use.
