We have developed a 10" Billet Big Wheel kit for the Pro Stock Inc 9.5" rear asphalt suspension. 10" Rear Wheels allow for better roll which equals more mph. They also shorten up notoriusly long track tension bolt extension. Our billet aluminum wheel assemblies are lighter than the 3.250" pin wheel sets and allow for a flatter footprint leading to better 60' times. Kit includes (3) Billet 10" rear wheels with bearings and (4) 3.625" billet wheel assemblies ready to bolt on using exsisting hardware. Kits are available in naked aluminum or black anodized.
