SKU: PRS910-34511-L Category:

The 3-piece Short Arm Metric Replacement Spindle to be used in conjunction with the 1979-up GM Metric front brake rotors, bearings and calipers. Advanced engineering techniques allowed for a redesign of the spindle in a newly forged, heat-treated steel design that is both stronger and lighter than the original. These spindles serve as a replacement for cars currently running Pinto/Mustang II setups. The 8 degree pin inclination not only improves handling and driver feel, but also dynamically adds cross weight to the car during counter steering which leads to increased drive off the corner. The shortened, dropped steering arm reduces spacing requirements on outer tie rods and minimizes bump steer while improving overall strength. Accepts ’79-Up GM Metric rotors, calipers, stock tapered lower ball joints and is reamed to accept 7 degree upper ball joints. The unique three-piece construction provides for fast, convenient and affordable replacement of individual components in the event of a crash. These spindles are IMCA/USMTS/USRA approved for use in competition.
