RTS ring and pinion sets are manufactured to exceed OEM specification that are required for todays modern performance vehicles. The design, tooling, material selection and heat-treatment recipes are all controlled by the RTS manufacturing factory to produce a cost-alternative ring and pinion set that does not sacrifice quality. They are available in a wide variety of gear ratios for your modern Holden Commodore or Ford Falcon with M75, M78, M80, M86 or ZF differentials.
