Strange Engineering continues to evolve its product line to meet the demands of today’s racers by bringing the latest in remote reservoir shocks shock technology to the drag racing market . The all new double adjustable “Piggyback” Ultra-Series shocks are a mono-tube design that reduce undesired changes in shock dampening during use. The unique “Piggyback” design features a gas charged reservoir, hardened super finished chrome rods, and a wide range of tuning adjustment. The large 48mm piston is manufactured from billet aluminum, hard anodized, and Teflon coated which result in higher dampening forces with lower internal pressure. The locking spring seat and remote reservoir also allow for longer and lighter springs with easier installation. Available in several lengths, the Ultra-Series remote reservoir shocks are completely rebuild able and revalvable to accommodate a wide variety of applications.
