Cognito Motorsports' new 4- to 6-inch adjustable suspension lift system for the '01-'08 GM eight-lug trucks is now available. The system uses a new spindle engineered to offer strength, flexibility, and ease of installation. On 4WD models, the front differential and lower control arm are dropped down 4 inches to avoid severe CV axle angles. This adjustable system comes with a patent-pending pitman arm and idler-arm support kit that eliminates the premature wear found in GM components. Also included is a skidplate that doubles as a subframe connector. This means that the front and rear crossmembers are connected to create a rigid subframe to position the lower control arms and front differential. The rear lift is achieved by a 2-inch block and a U-bolt kit. Bilstein shocks are used for damping. Cognito Motorsports, 866.426.4648, www.cognitomotorsports.com

Here's Downey's "old faithful," the original adjustable suspension system for '00-'06 Toyota Tundras. Downey was first on the market with its Tundra suspension kit. It features a 30-percent heavier-duty spring rate and taller coils with more wraps to increase travel, mounted onto world-famous rebuildable Bilstein shocks for precision and quality.

Fabtech's '01-'08 GM K2500 HD 9-inch long-travel coilover conversion system eliminates the factory torsion-bar assembly. It also replaces it with a coilover shock configuration for increased ground clearance at the frame. It offers excellent ride characteristics both on- and off-road. Included are replacement extended-length upper tubular control arms and lower-plated and boxed-style control arms to support the load of the Dirt Logic 4.0 coilover shock. The control arms feature Delrin frame bushings with 1-inch Uniballs in the upper arms and a heavy-duty ball joint in the lower arms. Control arms are 1-inch longer than stock and will provide 12 inches of wheel travel without bind. To compensate for this increased track width, Fabtech includes 1-inch per side, reduced-offset steering knuckles. Fabtech Motorsports, 877.432.2832, www.fabtechmotorsports.com
Genuine Suspension now offers 6- and 8-inch suspension kits for the '05-'07 Ford Super Duty. The 6-inch kit will allow the clearance of 35-inch tires, and the 8-inch kit will clear 37-inch tires.

ORU has released its GM IFS-to-solid-axle conversion kit for '01-'08 GM 2500 and 3500 HD 4x4 trucks. The bolt-on kit will allow you to convert your '01-'08 independent front suspension to a solid axle with four-link and coilovers. With this kit and the stronger axle in place, you can run 37- to 40-inch tires. The system comes complete with all necessary brackets and hardware, adjustable 2.5-inch front coilover shocks, front axle assembly, brake lines, rear springs, and shocks. The only other items required are a complete front driveshaft and a rear driveshaft modification. Off Road Unlimited, 818.563.1208, www.offroadunlimited.com
The '05-and-later Ford F-250 and F-350 4WD 6- and 8-inch coil-spring radius-arm suspension is a totally new design. The lift system converts the Super Duty's two-link design radius-arm suspension to a four-link front axle mounting with ICG (instant center geometry), reducing the total caster change throughout the suspension's movement by over 70 percent. The result is improved on-center feel and control when driving or towing. This system can be used with Full-Traction heavy-duty coil springs or the optional coilover shock kit and includes Kevlar-lined 4130 chromoly heavy-duty rod ends and 2-inch-diameter 0.250-inch-wall thickness DOM chromoly tubing for the lower leading control-arm assemblies.
