CST 2019+ Silverado & Sierra 1500 Dirt Series Coilover # CSA-3506

This CST Performance Suspension CSA-3506 coilover will fit 2019, 2020, 2021 and 2022 model year Chevrolet Silverado 1500 and GMC Sierra 1500 trucks. The CST # CSA-3506 Coilover Kit is designed to actually improve the factory ride quality! This coilover includes a pair of top quality (and world famous) Eibach coil springs. When driven off-road the CST coilover helps to prevent the frequent bottoming out that is common with the factory shock and spring. Each coilover is built using CNC machined components, feature Parker brand seals and wear components, and PTFE lined spherical bearings for quieter performance and longer life.

Tire & Wheel Information:
CST recommends the use of a 33" to 35" tall tire on up to 9" wide wheels. Maximum recommended back space is 5.70" inches when running a 17" diameter wheel. It may be necessary to pull the factory inner wheel liner away from the tire to prevent rubbing when turning. Use of wide (10" or more) or low offset wheels will require additional trimming to clear larger tires. Don't want to trim? Run a narrower wheel with the correct backspace!

ARC / Trail Boss / AT4 Fitment Information:
This coilover is not for use on vehicles equipped with ARC (Active Ride Control). Yes, this coilover can be installed on Silverado 1500 Trail Boss and GMC Sierra 1500 AT4 models. Please note however the maximum additional lift height will only be approximately 1.00" to 1.50" over the factory height. Again, on Trail Boss and AT4 models the maximum lift height possible will be less than on "standard" suspension trucks because the truck is already equipped with a factory installed 2" lift.

The CST coilover is a direct 100% bolt-on replacement for the factory front shock and spring assembly. If you would like to put together a complete front and rear shock package we also offer CST rear shocks available for purchase separately. CST sear shocks are NOT included with this item! The CST rear shocks work very well when matched with the CST coilover and are also a direct 100% bolt-on shock.
