PERFORMANCE HANDLING KIT W/ FRONT COILOVERS/SPINDLES & SWAY BAR - 350345HK

Fits: 2019+ GM Silverado / Sierra 1500 2WD / 4WD

-2” to -4” Front and -4” Rear

Advanced performance, improved handling, and enhanced style are just a few of the upgrades you gain when swapping your OE suspension for Belltech’s 2019+ GM Silverado / Sierra 1500 Performance Handling Lowering Kit. With a front height adjustment of -2” to -4” and the rear -4” lowering, you achieve the look, performance, and ride quality you need.

We utilize our time-tested drop spindles to lower the front of your GM -2” closer to the ground. Belltech drop spindles are made of high-strength ductile iron and are powder-coated for a long-lasting, durable finish. Our GM drop spindle is specifically designed to retain your truck’s factory suspension geometry. We add robust Belltech lowering coilovers designed using high-quality, multi-functional components that are built to last. Each coilover includes a finely tuned Belltech threaded damper. The dampers feature a large, 2.4” (60mm) damper body and 35mm independent rebound and compression valves. Together, these details keep oil cool and deliver precise, consistent damping throughout suspension travel. The external threads and durable spring perch offer additional height adjustability to set the stance you want. We feature a large main spring and smaller helper spring. Both the main spring and the helper spring are made of cold-formed tensile steel and are powder-coated to prevent rust and wear. The coilover is completed with a progressive rate polymer, open-cell, bump stop for ideal bump stop engagement. Belltech GM coilovers are designed to use the OEM top mounts for simplified installation.

For lateral control we include a 1-3/8” diameter solid front sway bar and 1-1/8” diameter solid rear sway bar that are made of cold-formed steel and powder coated for longevity. Both sway bars feature 3 settings of adjustability to meet your specific performance needs.

The rear end of the vehicle showcases Belltech Street Performance shocks that are preset and perfectly tuned for your GM. They feature large 2.1” (55mm) damper bodies and use 35mm independent rebound and compression valves; the result is exact, luxurious damping. Like the coilover dampers, our shocks are made with a low-friction design and use a rust-preventative coating to increase their lifespans. To achieve -4” in lowering, our kit includes an easy-to-install Belltech shackles to reposition the rear leaf spring mounting points and are fitted with OEM style bushings to retain ride quality. We complete the kit with our new Belltech lowering leaf springs made of high-grade spring steel and OEM quality bushings.
