Penske 8770 4-way Shock Absorber

The 8770 car damper is the latest evolution of this true 4-way, which is destined to again enjoy success in motorsport. Other 4-way dampers exist from various manufacturers, but many have 3 compression adjusters and a single rebound adjuster. By offering high and low-speed compression and rebound, the 8770 offers the most versatility with external adjustment which reduces the need for revalves. Having 4 clearly defined adjusters, 2 affecting bleed and 2 affecting high-speed forces, chassis tuning becomes more simplified to the end user. The bleed adjusters target low-speed transient movements (pitch, roll, heave, and warp) of the chassis (sprung mass) within the 4 wheels while the high-speed adjusters tune the transmission of external road inputs into the chassis. The 8770 is based on proven technology that gives considerable range of adjustment and winning performance in a compact, lightweight package for the serious racing team. * True 4-way design * Ø 9/16” shaft for reduced friction and weight * Piggyback layout for packaging advantages * Extensive Adjustability * Low-Friction seal selection * Easy bleeding with 3 bleed access ports * Modular design for extensive versatility of radial reservoir and adjuster positions * Ability to be offered with a Penske dual-bleed shaft if desired * Ability to be offered with a Penske single-adjustable shaft if desired * Offered in all body lengths in stock
