Show original supplier description
The Rancho RS6548B Primary Suspension System provides a 4-inch front lift and a 2.5-inch rear lift, allowing for the installation of larger tires up to 35 inches in diameter. This kit features a one-piece reinforced subframe constructed from high-strength, low-alloy steel, and extended cast steering knuckles to maintain factory steering geometry. This suspension system includes essential components like U-bolts, a riser block, and brake hose brackets. Importantly, the installation of the Rancho RS6548B requires no drivetrain or exhaust modifications. However, proper tire clearance may necessitate minor trimming. Please note that shocks are sold separately and must be chosen to be vehicle-specific. Rancho backs this suspension system with a Limited Lifetime Warranty, covering defects in materials or workmanship when used under normal operating conditions by the original purchaser on the original vehicle. This warranty is valid for privately owned passenger cars or light trucks and does not cover products modified, improperly applied, or installed on vehicles used for commercial or racing purposes. Installation by a professional is recommended due to specialized tools that may be required, and a vehicle alignment is necessary after installation.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.
