Strange Engineering brings advanced shock technology into the Drag Racing market. As racers become more knowledgeable in chassis tuning, many are seeking qualities normally reserved for tier one vehicles used in other forms of motorsports. These double adjustable shocks address the internal events that normally occur during use, drastically reducing undesired changes in shock dampening. Monotube construction is lighter (and less unsprung weight) than a twin tube design, and dissipates heat more efficiently. The shock features a hollow shock rod, which has less inertia making it more responsive to changes in direction; In addition, the shaft is optimally hardened for increased strength, chromed, and super finished to provide superior life and reduce both deflection and friction. The ultra low friction guide and seal are self aligning that reduces low speed abrasion and wear that occurs during side loading and temperature changes. The large 48mm piston is manufactured from billet aluminium, hard anodized, and Teflon coated. The larger piston area achieves higher dampening forces with lower internal pressures. A thin Teflon coated piston band further reduces friction while allowing a straighter port design that minimizes changes in fluid direction. The result is faster frequency response and lowered hysteresis, which permits a more progressive dampening force without the downside of additional lag that would normally accompany it. The extension and compression oil paths are completely sealed from each other eliminating any cross talk between them.
