Rock Krawler 3.5 Inch Drive Right Mid Arm System - 2018+ Jeep Wrangler JL 2-Door

Most lift kits add height and leave you to sort out what that does to the geometry. The Drive Right System works the other way around: it exists to put the geometry back where it belongs after you lift a 2018 and newer Jeep Wrangler JL (2-door). An adjustable front track bar recenters the front axle, a raised rear track bar bracket recenters the rear and improves the rear roll center, and adjustable high-clearance front lower arms let you dial in caster without shortening the wheelbase the way adjustable uppers do. And when the build grows, it upgrades to the Adventure-X mid arm system without starting over.

What's in the kit

• (4) Triple-rate coil springs
• (2) Front adjustable lower control arms
• (2) Front spring pads
• (1) Adjustable front track bar
• (2) Rear spring pads
• (2) Adjustable rear sway bar links
• (1) Bolt-on rear track bar relocation bracket

Shocks depend on the package you pick below. Bump stops come with every shock option; if you go with no shocks they can be ordered separately (Rock Krawler part RK07124).

Why this system

• Complete bolt-in system, so no cutting or welding to get it on the Jeep.
• Tuned triple-rate coil springs with spring correction pads give excellent highway ride and built-in lean correction.
• Track bar geometry corrections front and rear, plus an improved rear roll center, keep the axles centered and the handling honest.
• The Jeep sits level on all four corners.
• Adjustable high-clearance front lower arms set caster and cross-caster without shortening the wheelbase, which is what adjustable uppers do when you add caster.
• Can be upgraded later to the Rock Krawler Adventure-X mid arm system, so you can expand the build without starting over.
• Eliminates dog tracking by properly centering both axles.
• Lifetime warranty coverage.

Pick your package

• Base System (No Shocks). The kit as listed above with no shocks, for the builder who already has shocks picked out. Bump stops come with every shock option; with this one they're ordered separately.
• Bilstein 5100 Shocks. The kit plus Bilstein 5100 shocks. Rock Krawler calls them maintenance free and a great pairing with its multi-rate coil springs.
• Stage 1 (RRD 2.25 inch IFP shocks). Rock Krawler's in-house shock: a 2.25 inch hard anodized fluted aluminum body with the cooling surface of a 2.5 inch shock, a 3/4 inch hard chrome stainless steel shaft, billet aluminum valving and dual DU shaft bearings. Serviceable, rebuildable and revalveable.
• Stage 2 (RRD 2.25 inch FCD shocks). Everything in the Stage 1 IFP shock, plus a Fast Compression Damping (FCD) adjuster that Rock Krawler quotes at up to a 30% increase, so you can fine-tune ride quality and handling.

Fitment and what else you'll need

Fits the 2018 and newer Jeep Wrangler JL (2-door): gas models with the 2.0L turbo four-cylinder, the 3.6L Pentastar V6 or the 3.6L Pentastar with eTorque.

Rock Krawler bases all lift heights on Rubicon models in a standard build (front bumper and winch, rear bumper and full-size spare). If you delete the spare, drop 1 inch of rear coil lift height; for an overland or heavily loaded rear build, go up 1 inch.

• Sport and Sahara: for 37 and 38 inch tall tires, Rock Krawler recommends 3.5 inches of backspacing. With full OEM fenders that means 37 inch tires; with trimmed or high-lined fenders, 38 inch tires (3 inch bump stop height recommended).
• Rubicon: 37 inch tall tires want 4.5 inches of backspacing and 40 inch tall tires want 3.5 inches. With full OEM fenders, 37 or 38 inch tires fit; with trimmed or high-lined fenders, 40 inch tires fit (3 inch bump stop height recommended).
• Rock Krawler recommends a new front driveshaft if you plan to off-road routinely.

Rock Krawler lists lifetime warranty coverage on this system. Posted lead times from Rock Krawler, in business days from order: mid arm kits 1 to 2 weeks, long arm kits 3 to 4 weeks, 2.25 inch shocks 1 to 2 weeks and 2.625 inch shocks or coilovers 3 to 4 weeks.
