Ridetech 4WD Lowering Kit for 2019-2025 Chevrolet Silverado and GMC Sierra 1500, Group B Axle
The Ridetech Performance Lowering System, MPN 11720116, is a bolt-on lowering kit for 2019-2025 Chevrolet Silverado and GMC Sierra 1500 4WD trucks equipped with a Group B rear axle, the stamped steel or aluminum rear lower control arm setup found on Trail Boss, AT4, and Z71 or RST off-road packages. The kit combines HQ Series adjustable front coilovers, a rear flip kit with a bolt-in C-notch, and HQ Series rear shocks to deliver a configurable 4 inch front and 6 inch rear drop, or a 5 inch front and 7 inch rear drop, while maintaining near-stock payload and alignment geometry. Installation is bolt-on with no welding or frame cutting required on most installations, and rear shock relocators and sway bar links are included.

Frequently Asked Questions
How do I confirm my truck has a Group B rear axle?
Group B trucks use stamped steel or aluminum rear lower control arms rather than cast iron. Most Trail Boss, AT4, and Z71 or RST models with off-road packages are Group B.
Will this kit work with MagneRide-equipped trucks?
Not without additional parts. MagneRide trucks require different front coilovers than the ones included in this kit.
Does this kit affect towing or payload capacity?
The kit maintains stock ratings when not exceeded, and an optional air assist kit is available for heavy loads.
Does installation require welding or frame cutting?
No. Installation is bolt-on, and the C-notch bolts directly to the frame on most installations.
What drop height options are available?
The kit offers a 4 inch front and 6 inch rear drop, or a 5 inch front and 7 inch rear drop, depending on configuration.
Is a professional alignment required after installation?
Yes. A professional alignment is required after installing this kit.
