Tenneco’s Rancho performance brand now offers a new 6-inch suspension system for 2018-17 Ford F-150 pickup trucks.

The new system (Part no. RS66506B) features a reinforced, fully boxed welded subframe manufactured from high-strength, low-alloy steel, and DOM tubing, the kit is specially designed to minimize vibration and ride harshness while offering maximum structural integrity and OE-level quality.

Carefully designed components ensure precise fit in a system engineered to maintain proper CV joint and driveshaft angles, steering geometry, track width and factory location of the rack and pinion. A pair of bolt-on, 6-inch strut spacers for the front of the vehicle are designed to install easily without the need to disassemble the factory struts.

Other kit features include CNC-machined extended steering knuckles, CV spacers, brake line brackets, sway bar relocation brackets, rear leaf spring blocks and other necessary hardware. For the front, two Rancho strut towers (Part no. RS88652) or a set of two RS5000X struts – each of which is sold separately – are required for complete installation.

For the rear, a tapered block, U-bolts, and other necessary hardware are provided. No drivetrain modifications are required for the system, which also utilizes OE tie rod ends and fits up to 35-inch tires. In addition, a set of two Rancho RS5000X, RS7000MT, or RS9000XL rear shock absorbers is recommended for a superior driving experience. Each Rancho suspension kit, along with RS5000X, RS7000MT and RS9000XL dampers, is backed by Rancho’s Limited Lifetime Warranty.
