Strange Forged Aluminum Stud Mount Drag Race Strut Front Suspension With Heavy Duty Brake Kit for Hub Mount Wheels.

This Front kit provides the basis for a lightweight front suspension. Frame construction is much simpler, suspension geometry is more easily established, and header clearance is improved over conventional A-frame suspension. Every Strange strut is externally adjustable for extension (rebound) for more convenient tuning. Strange double adjustable strut packages provide an additional external adjustment for compression (bump). Strange aluminum strut bodies are forged from 2000 series aluminum alloy to provide high strength at a minimal weight. Heat treated 17-4 stainless steel spindles provide an exceptionally strong wheel mounting surface.

Fatigue resistant steel steering arms can be formed easily to obtain proper steering geometry. Brake mounting bosses are an integral part of the forged housing, providing simplicity for brake kit mounting on either side of the strut. Every Strange strut package features integral designed components ensuring proper fit, ease of assembly, maximum performance and an unsurpassed regard for safety.

All Strange forged aluminum struts are for Drag Racing only.

Strange Heavy Duty front brake kits offer a tremendous weight savings over OEM brake components. The kit includes bearings, hubs, rotors, pads, calipers, & pads. Strange Engineering’s brake kits are unsurpassed in detail. One example of our unparalleled attention to detail is evident in our hub design. Each hub has one bolt circle. Instead of adding an additional bolt circle, the hub is scalloped and lightening holes are milled to reduce rotating weight. The hub cap is fully machined and hollowed out to maximize weight reduction. We feel that the extra effort into weight reduction is expected from customers who want a premium quality Drag Racing brake kit.

Strange Control Arms
The packages include the components needed to mount your struts to the frame rails. The tubes are manufactured from 4130 chromoly and include adapters and rod ends.

HYPERCO SPRINGS: Cold wound from preheat treated SAE 9254 chrome silicon wire. Optimum wire diameter is selected for the individual design without compromise. After coiling, the closed ends are ground, and the spring is thermally stress relieved, preset and shotpeened. Completed springs are magnafluxed, inspected, deep blue epoxy powder coated and checked for dimensions, trueness and rate. Hyperco then tests each coil for actual rate and etches the rate permanently into the spring. Hyperco strict manufacturing tolerances assure the racer of springs within a tolerance range of +/- 2%- most being within 1%!
