Fox Racing Shox 2.5 Performance Series IFP Smooth Body HTO Shocks

FOX 2.5 Performance Series IFP HTO shocks are bolt-on units loaded with position-sensitive technology, vehicle-specific valving, and larger pistons to improve on and off-road performance.

They also feature Hydraulic Top Out (HTO) technology that offers usable position-sensitive rebound damping control on and off the pavement. HTO reduces harsh top-outs and increases comfort by forcing shock oil through a secondary shim stack to slow down shock shaft speed, which is particularly beneficial after installing heavier, aggressive tires and applications lifted higher than OEM specification. Bolt-on 2.5 Performance Series HTO shocks to increase damping capacity and ride in comfort with position-sensitive rebound control. Select the Fox shocks designed for your vehicle.

BD Diesel Tie Rod Upgrade Kits

A major common weak point on Chevrolet/GM HD series trucks is the steering linkage and tie rods—with high-torque engines, lift kits, and larger tires putting greater strains on the steering system than what OEM intended. Common failures include loose steering, front wheels toe-in under load while in 4WD, and broken tie rods. If you have performance upgrades in your truck, lifted it or do serious towing, it's time for a tie rod upgrade kit from BD Diesel. In kit P/N 1032125, the forged I-Beam centerlink is 30 percent stronger than OEM, which reduces flex in the steering system and creates a strong base for the tie rods to be attached to. The tie rods are 1.5x thicker than OEM for reduced flex and have larger inner ball joints for reduced wear. Testing has shown the BD tie rods can take over double the amount of force that OEM rods can handle. Greaseable ball joints come with sintered bearings and allow for better load holding and increased life. Longer, high-strength through-bolt designed sway bar end links are included to accommodate larger tie rods and leveling kits. Polyurethane bushings have OEM-style shaping for articulation and durability. The entire kit retains factory geometry for accurate steering and will allow for any OEM replacement parts to drop-in without any geometry sacrifice or modification required. Other upgrade kit designs change the geometry of the steering, which can sacrifice safety and drivability for straight line strength while pulling or racing. This can also create a dangerous "bump steer" where the vehicle becomes uncontrollable on uneven roads. By not altering the steering geometry, the BD upgrade kit saves you from this problem. The total package is an economic upgrade for worn-out steering and will increase the durability, longevity, and dependability of your truck—while saving money by preventing catastrophic repairs. See if there's a tie rod upgrade kit that's compatible with your vehicle.
