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 kit will lift the front of your 4runner 1.2-3.5" These shocks are designed to work with rear lift heights from 0-2.5". This listing is for a pair of front coilovers and a pair of rear bypasses. We also carry matching rear external bypasses designed and tuned for your rig by professional engineers. The 8112 Zone Control 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. These are the shocks we run on our personal truck, now optioned with tool-less adjusters and a new state of the art coating. Bilstein's 8100 series are a direct fit, 2 tube external bypass. This lets you adjust your compression and rebound zone independently while providing a plush "ride zone". The engineering concept behind these is to give you the best ride comfort and handling on road, while also taming large suspension inputs off-road. During normal daily driving you have the control of the full size 60mm main piston, you can take your rig to work, pick up a load of gravel, or hit twisty mountain roads with maximum comfort and control. Off-road, the large external bypass tubes let some oil "bypass" the main piston valving to get your suspension moving over the rough stuff. The final compression zone is tuned as a bump zone and the bottom rebound zone serves to slow down harsh top out events. If you tuned normal smooth body shocks to work as good off-road, they would be miserable on-road, and vice versa. The reservoir hose attaches to the base of the shock, which delivers increased compression control during the full cycle and keeps the seal assembly cooler. Everything about this bypass is built for the rear end of your 4runner. The reservoir position is 100% custom fit as well as the valving and even the bypass zone placement itself is specific to this application. This is not a bypass that just fits a 4runner, this is a bypass built from the ground up for your 4runner.
