We think it's man's nature to toil away on, tinker with, and fix everything we touch-even when things don't need fixin'! Our vehicles are no exception. The first thing we do when we get a truck in our clutches is tear it apart, then build it back up again. So to help you out in your quest to better your new, vertically challenged, fullsize trucks, we gathered up all the top suspension manufacturers. If you are building your truck for real-world use, then these manufacturers should have a setup for you.

This ARB suspension system is a complete performance lift kit for the '07-and-up 4WD Toyota Tundra. It's designed to lift the vehicle 2.5 inches front and rear with Old Man Emu components. Multiple spring rates are available for the base-model light-duty trucks to the Highline models with the 5.7L V-8, fitted with or without a Bull Bar and winch. Improved ride quality, a reduction in brake dive, and better trailer and weight control are attained by using new full leaf springs, uprated coils, and OME struts and shocks valved specifically for this vehicle. ARB USA, 888.427.2872,

This coil-spring suspension system and solid-axle swap is for the '99-'07 Chevy K2500 and will allow a Ford Dana 44, Dana 50, or Dana 60 axle (kingpin or ball-joint style) swap. It provides 6.5 inches of lift front and 3.5 rear. The kit comes with all the custom parts necessary to do the conversion such as upper and lower coil-spring mounts, progressive-rated performance coil springs, dual shock mounts, four nitrogen shocks, radius arms, an adjustable track bar with bushings and a rod end, an upper track-bar mount and crossmember combination, a lower track-bar mount for the axle, and custom weld-on mounts. Rear lift components such as shocks, U-bolts, and blocks are also provided. CAGE Offroad Products, 866.587.2243,

The new 8-inch lift system for the Super Duty is centered around four massive control arms that replace the stock radius arms with a four-link suspension design. The four-link offers improved on- and off-road control versus a standard radius arm. These arms are attached to new heavy-duty mounts at the frame. The BDS mounting brackets replace the OE mounts and bolt directly to the frame to increase the rigidity and control of the suspension. The greaseable control-arm ends use giant 2.5-inch od urethane bushings that are both internally and externally fluted to ensure long-term performance, reduced noise, and increased vibration damping. A forged pitman arm is used to drop the drag-link angle, and a reinforced track-bar relocation bracket is used to match the angles. This system also includes new front and rear braided, Kevlar-lined, stainless steel brake lines; sway-bar drop brackets; extended bumpstops; a steering stabilizer; and rear exhaust relocation brackets for the diesel models. BDS Suspension, 517.279.2135,

The Performance 2.0 suspension system is built to offer excellent on- and off-highway performance. The system's multirate coil rates give a lighter-than-stock rate on the street, but a higher rate built in for off-road travel. The proprietary valving profile is set up for freeway driving with room for additional tuning for light to moderate off-road performance. This custom valve profile and every other aspect of the components have been tuned specifically for the 2500 and 3500 Dodge Ram CTD. The balanced ride is designed to prevent high-speed bucking on freeway expansion joints or while cornering. The Performance 2.0 system includes Bilstein 2-inch 7100 remote-reservoir shocks, a five-leaf progressive Add-A-Pack, multirate coil springs, an adjustable track bar, stainless sway-bar end links with F.K. bearings, a machined billet clevis with hardware, zinc-plated U-bolts, powdercoated reservoir mounts, and limit straps. Carli Suspension, 714.532.2798,

The CST Performance Suspension systems for GM trucks drop the factory upper and lower control arm, steering, and differential components a true 6 or 9 inches. This system's design maintains the factory steering and CV geometry so that the original track width is retained. The 6-inch HD lift system provides durability and factorylike ride through with a unique one-piece subframe design with strut-bar supports. Supported upper control-arm drop mounts and a steering drop-down assembly, which includes a steering stabilizer and Heim-jointed support linkages, ensure idler and pitman-arm stability. CST Performance Suspension, 951.571.0212,

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,

Doetsch Enterprises now offers a full range of lift kits for '07-and-up Chevrolet 1/2-ton pickups. Doetsch makes kits with height ranges of 2, 3, 4, and 6 inches to accommodate larger wheel-and-tire packages.

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,

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.

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.
