Bilstein's 8112 Zone Control Coilovers are an upgrade to internal bypass style shocks, with 5 total damping zones that eliminates the need for hydraulic bump stops or limit straps. They use a triple piston design with the most mechanically advanced internals on the market. These shocks have an unrivaled full size 60mm working piston and 3 compression zones and 2 rebound zones. This combination offers unparalleled ride comfort and handling during daily driving, combined with maximum control over large suspension inputs off-road. When compared to a custom tuned coilover/bypass/airbump setup it's all the performance at a fraction of the cost and install time.
The main seal assembly is based on a military contract part manufactured for 5 ton tactical trucks, and the JCO is built in the same factory as supercar shocks. As long as the shocks are not physically damaged they should average around 100k miles before needing serviced. Since these shocks came out in 2015 I have yet to rebuild one that was leaking, but if that does ever happen you are eligible for 20% off all shock services for products purchased through us. Every single 8112 is dyno tested before shipping to ensure every single zone works perfectly at every speed.
This listing is for a pair of Coilovers. We also carry matching rear external bypasses designed tuned for your rig by professional engineers. The 8112 internal bypass technology is the current shock to beat for OEM replacement. We have personally installed a couple dozen of them and the feedback has been extremely positive. There isn't another product on the market that gives you internal bypass performance with a full sized piston for maximum damping, while also incorporating an air bump, all in 1 shock that fits perfectly in the stock location.
If we are out of stock, these shocks are built to order with an estimated 8-week lead time.
