Silverback Pro Elite swaps the lower control arms for billet 7075 aluminum, front and rear, and keeps everything that makes the Silverback layout work: a high clearance 4-link front, a triangulated 4-link rear without a rear track bar, and service-free Adventure Series joints. It is a 4.5 inch long-arm kit for Sport, Overland and Mojave Gladiators that get driven hard and driven daily.

Why this system
- Front and rear lower control arms are billet 7075 aluminum
- Triangulated 4-link rear eliminates the rear track bar for smoother highway handling and better axle centering
- Service-free Adventure Series joints in the long arms
- Triple-rate front and quad-rate rear coils with coil spring correction seats
- Carrier bearing bracket and rear brake line kit included
- Bolt-on Pro-X rear cradle with optional welding
Pick your package
- Base System (No Shocks): the lift hardware only, no shocks. Pick this if you are supplying your own shocks. Bump stops ship with each shock option, and with no shocks they can be bought separately as RK07464.
- Bilstein 5100 Shocks: the Bilstein 5100 package, a maintenance-free option Rock Krawler says works well with its multi-rate coils. Bump stops are included.
- Stage 1 (RRD 2.25 IFP Shocks): the in-house RRD 2.25 inch IFP shock: military grade hard anodized fluted aluminum body (cooling surface of a 2.5 inch shock), a 3/4 inch 17-4 PH stainless shaft with hard chrome plating, billet aluminum valve circuit, dual DU shaft bearings and redundant sealing. They can be serviced, rebuilt and revalved. Bump stops included.
- Comp System Stage 1: front coilovers with a rear coil spring. Up front are 2.625 inch RRD remote reservoir coilovers (13 inches of travel for 14.44 inches of axle travel), paired with 2.625 inch RRD remote reservoir rear shocks (12 inches of travel for 15 inches of axle travel). A fit for trucks that still haul small loads or pull small trailers. Includes the rear quad-rate coils and spring correction seats.
- Comp System Stage 2 (Fast CD): same Comp System layout plus Fast CD adjusters on the front coilovers and rear shocks, which add up to 30% more compression damping with infinite settings.
- Trail Runner Stage 1: a coilover at every corner using 2.625 inch RRD remote reservoir coilovers. Rock Krawler says this gives the most off-road ability and a well-tuned street ride; the tradeoff is that rear coilovers do not like changing loads, so heavy bed loads and towing are not ideal.
- Trail Runner Stage 2 (Fast CD): the Trail Runner layout with Fast CD compression damping adjusters on the coilovers.
Fitment and what else you'll need
- Fits the 2020+ Jeep Gladiator JT, 4 door, 4WD, Sport, Overland and Mojave trim levels. Engine: 3.6L Pentastar V6 (gas models)
- Rock Krawler wheel guidance: Sport and Overland, 3.5 inches of backspacing with 37/38 inch tires; Mojave, 4.5 inches with 37 inch tires or 3.5 inches with 40 inch tires
- Tire guidance (3 inch bump stop height recommended): Sport and Overland, 37 inch tall with full OEM fenders or 38 inch with trimmed or high-lined fenders; Mojave, 37/38 inch tall with full fenders or 40 inch with trimmed or high-lined fenders
- Lift height is figured on a Rubicon with a standard build (front bumper and winch, rear bumper, full size spare). Delete the spare and Rock Krawler suggests dropping 1 inch in rear coil lift height; load up the rear overland-style and they suggest going up 1 inch
- Rock Krawler recommends a new front driveshaft if you plan to off-road routinely (they name Adam's Driveshaft, Tom Woods and J.E. Reel)
- Welding the rear cradle is recommended for 37 inch tires and larger
- Long arm install requires welding of the front long arm mounting system; removal of the OEM frame side lower front control arm mounts; removal of the OEM frame side front upper control arm mounts; removal of the OEM axle side track bar mount
- Coilover packages (Comp System and Trail Runner) require removal of the OEM frame shock mount and the OEM shock and spring mount on the axle, plus welding of the new coilover mount to the axle only
