The Ridetech 3/5 drop lowering suspension system for 1999-2006 Chevy Silverado and GMC Sierra 1500 2WD trucks includes everything you need to get your trucks stance looking good.
We focus on the areas of the OE suspension that need improvement. In the case of 99-06 GM trucks that means keeping the factory control arms and leaf springs.  Getting down to business, we start with heavy-duty C-Notches that are unlike anything else on the market. The C-Notches are significantly longer than other design and feature reinforcements in multiple planes. They provide ample axle clearance while maintaining frame strength, both torsionally and longitudinally — even when carrying a load.
Beyond a sturdy foundation, the next most important part of this lowering system is, by far, the custom valve rebound adjustable mono tube shock absorbers. Ridetech shocks feature superior monotube damping control inside of an impact forged housing. Monotube shocks are more responsive than twin-tube shocks and provide far better body control.  Built-in shock rebound adjustment lets you fine-tune the valving to suit your personal driving style. Just a quick turn of the adjuster and you can dynamically change how your truck responds.  Ridetech includes rear shock extender brackets that maintain proper shock angle. It really is remarkable how well these trucks go down the road with the right set of shock absorbers.
To get the front of the truck down, the Ridetech system includes custom-matched coil springs in conjunction and forged “Drop” spindles.
The springs work in conjunction with the rebound adjustable monotube shocks to add significant ride and handling improvements. The spindles lower the vehicle while maintaining suspension geometry and alignment. Brand new grade 8 hardware and heavy-duty, powder-coated brackets round out the system. Ridetech did not skimp or cut any corners.
