Bilstein B8 8100/8112 Shock Absorber Kit | 07-21 Tundra

This complete 4-shock dynamic kit pairs the revolutionary Bilstein B8 8112 front coilover system with B8 8100 rear reservoir shocks, offering maximum comfort on the street and unmatched bottom-out control on the trail.

The front 8112 struts feature Bilstein's ZoneControl CR technology—a triple-piston design offering 3 stages of compression and 2 stages of rebound valving that instantly adapts to your suspension's position. You also have the option to upgrade to the DSA+ (Dual Speed Adjustability) front coilovers, which add click adjuster knobs for easy and precise tuning of both low and high-speed compression, plus an adjustable JCO (internal hydraulic bump stop).

For the rear, choose between the standard B8 8100 reservoir shocks (accommodating 0-1.5" lift) or upgrade to the B8 8100 Bypass rear shocks (accommodating 0-2.5" lift). The Bypass option features a dual-tube externally adjustable bypass design with "Incremental Flow" adjusters, allowing for finite changes to rebound and compression to dial in your exact load and terrain.

Check the specs and see why customizing your Tundra with a complete Bilstein 8112/8100 kit is the ultimate move for your daily commute, weekend rock-crawling adventure, or heavy-duty towing setup!
