What ARP bolt are those of you with ATS spindles using? My application is a 69' camaro.

Thanks in advance

If your talking about the wheel stud, the upgraded bolt on mine is a 1/2 20 thread 3 inches long.

The knurl is around .505-.509. Make sure to measure it though....that is what I needed in my C6 spindles.

The stud used is ARP part number: 100-7703.

This peticular stud uses a 0.625" knurl which means that the existing holes have to be machined, NOT drilled... to accept the 0.625" knurl and maintain the proper "interfearance" fit required.

If you were to receive your hubs and/or spindles with the stock fasteners and wanted to upgrade... the 100-7708 will work with minimal work.

However, the 0.625" knurl offers some mechanical advantages over that of any other stud that can be used after market... next to that of the 5/8ths fine thread studs... 300 series part number appications... which is what I use for my personal bearing packs.
