Fabtech 07-18 GM K1500 w/OE Forged UCA 3.5in UCA System w/DL 2.5 Resi Coilovers & Rear DL Shocks

If you're looking to give your 2007-2018 GM K1500 a significant lift and improved off-road performance, this Fabtech 3.5-inch Uniball UCA System is a solid choice. It's designed to handle aggressive driving while also offering a more controlled feel on the pavement. This system is built to accommodate a range of GM K1500 trucks, including models like the Chevrolet Silverado 1500 and GMC Sierra 1500, providing a substantial upgrade over stock suspension components.

At the heart of this system are the Uniball Upper Control Arms, constructed from .120-inch wall 4130 Chromoly tubing with a 1.50-inch outer diameter. These arms replace the factory upper ball joints with 1-inch FK Stainless PTFE Uniballs, offering superior strength and reducing the flex found in stock arms for a more direct road feel. The added caster built into these arms also helps with alignment, especially after leveling kits, and allows for increased wheel travel when paired with the included Dirt Logic 2.5 coilovers. These coilovers are tuned for 10 inches of front wheel travel, making them ideal for challenging terrain. The kit also includes front differential drop brackets, a 1/4-inch thick steel skid plate for protection, and 1 1/2-inch rear lift blocks with U-bolts to achieve the desired stance.

Completing the package are the Dirt Logic 2.25 rear shocks, designed for aggressive off-road use. The 4340 heat-treated uniball pin on the control arms fits into the factory ball joint taper without modifying the spindle, making it easier to return to stock if needed. This system is a direct replacement for factory arms on suspensions that require additional strength and better alignability, offering a comprehensive solution for enhancing your truck's suspension.
