Product Details

Shock Surplus has made your install easier with this fully assembled 6112 Coil & Spring kit. Bilstein's 6112 shock and spring package is designed for the adventure enthusiast wanting more out of their daily-driver or weekend ride. Extremely capable not only off-road, but also dramatically improves on-road handling characteristics and road feedback. The height adjustment of the 6112 kit allows the drive to remain at factory height, or to level out the front end of the vehicle for larger wheel and tire clearance. This Bilstein kit rivals 2.5" race-series shocks and coilovers from the competition, in an easily accessible performance package that can get you almost anywhere off-road. The 5100 monotube design and patented digressive valving is uniquely suited to confront these demands. On or off-road, loaded or unloaded, Bilstein shocks instantly react to changing road inputs to maintain a stable, controlled, and comfortable ride. Bilstein's superior monotube high gas pressure design allows the excessive heat from the oil to transfer to the outer surface of the shock body and dissipate more efficiently. The dividing piston also permits the oil to expand as heat builds, preventing aeration (foaming) and viscosity loss. This allows the shock to maintain full damping characteristics as temperatures rise.

I love them. Great on Highway ride. Can’t wait to get them oof road and put them to the test.

Shock Surplus Bilstein 6112 Strut & Spring Assembled + Rear 5100 Shocks Set for 2019-2024 Chevrolet Silverado 1500 Trail Boss 4WD Review

A massive upgrade over stock sr5

I installed the rear 5100's first and test drove it and you could instantly feel the improvement. After installing the 6112's the ride improved even more! Haven't gotten off the pavement yet, but on road the Tacoma handles/rides great. Feels really supported while also feeling soft off the top, if that makes sense.

Bilstein 5100 2021 silverado

The only reason I did 4 stars instead of 5 is because the shocks didn't lift the front of the truck as much as they said they would but the ride quality is so much better. It's surprising how much better they are then the stock shocks

01/10/2024

Good fit

Vehicle is smooth and runs like a champ. 100% recommended.

30/09/2024

Good shocks and good brand to go through shock surplus is really good
