Sonnax Smart-Tech input housing kits address the weak areas of 4-speed automatic transmissions. Flexing and bowing of OEM and other aftermarket backing plates is eliminated with Sonnax's heavy-duty bolt-on anchoring plates. Their unique design ensures even clamping of the 3-4 clutches in higher horsepower, higher pressure applications. By eliminating the 3-4 snap ring and using a thinner, yet stiffer apply plate, space is made available for additional frictions and steels. This makes it possible to simultaneously increase clutch torque capacity and eliminate the possibility of retaining ring blow-out. A steel reinforcement sleeve prevents breakage in the spline area. Housing fatigue/failure-resistance and housing life are significantly improved with a special treatment process that greatly reduces stress crack formation.

ACDelco Gold remanufactured rack and pinion assemblies convert the rotation of your steering column to the side-to-side motion needed to steer your front or rear wheels. These assemblies are an aftermarket replacement for your vehicle's original components. Remanufacturing the rack and pinion assemblies is an industry standard practice that involves disassembly of the existing units, and replacing components that are most prone to wear with new components. Damaged and obsolete parts are also replaced and end-of-line tested to ensure they perform to factory specifications. In addition, remanufacturing returns parts back into service rather than processing them as scrap or simply disposing of them. These Gold remanufactured rack and pinion assemblies are built provide the same performance, durability, and service life you expect from ACDelco. Order the model recommended for your vehicle
