The Street Door is manufactured with 6061-T6 aluminum and features 28% wider bearings over stock. The bearings are retained with a 6-bolt steel 1/8″ plate, phantom clutch lever movement is reduced by 90%. Improved transmission function is complemented with Function Formed design cues.
Increased axial loads generated by the helical gearset allow the stock door beveled snap rings to compress, allowing the door bearings to walk in performance applications. The Street Door corrects this shortcoming and is a requirement for any serious motor upgrade.
Installs with no modifications and includes ARP fasteners, mainshaft and countershaft nuts.
