Construction & Design:

Rancho’s Short Arm Suspension System is crafted from high-strength materials engineered to withstand the rigors of off-road use while delivering long-lasting durability. The system features a forged Pitman arm and heavy-duty tubular front links that resist bending and flexing under extreme conditions. Precision-engineered brackets and relocation components ensure that suspension geometry and driveline angles remain within factory specifications, reducing wear and vibration. The design also accommodates Rancho’s progressive rate coil springs, which provide a balanced combination of ride comfort and load capacity.

Installation & Fitment:

This suspension system is designed for direct fitment on 2018–2023 Jeep Wrangler Unlimited models, including Rubicon, Sahara, Sport, Willys, Moab, and special editions such as the 80th Anniversary and High Altitude trims.

Most systems work with stock wheels, and Rancho recommends replacing the rear driveshaft with Powertrain Industries part number 3194-2687 to prevent clearance issues during maximum articulation. Optional extended travel shock absorbers and aftermarket double cardan front driveshafts are available for enhanced performance.
