Installation parts are now sold separately from the gear set. Please select the required install kit when ordering either type RA or type STI gear sets. Base kit includes main shaft, 1st to 5th gears, and speedometer gear. '99-'01 turbo models (non-USA models) should order MY02 WRX install kit.

A Version 4 RA gearset is available to fit '95-'98 models. Please contact us for pricing and availability.

This is the least expensive way to substantially increase the reliability of the WRX gearbox. Only Rallispec RA & STi gearsets feature the REM isotropic superfinishing process (micro-polish) now treated entirely in-house. ISF provides substantial benefits in terms of reducing gear tooth friction and eliminating surface imperfections (stress risers). REM ISF is used extensively at the highest levels of motorsport (F1, WRC, Nascar). Our real world testing has shown huge improvements in reliability far beyond any other surface treatment we have tested.
Type RA sets are close ratio sets for maximum acceleration and performance.
Type STi sets are similar to stock (slightly closer ratio in 1st, 2nd, and 3rd) for better highway performance and top speed capabilities. RA has a slight edge in torque capacity over the STi sets.

Install kits come with the parts necessary to properly install the gear set into your particular vehicle. At minimum the kit will include a full set of shaft lock nuts, case gasket, and oil seal. Some kits will include additional parts such as updated synchro hubs, thrust washer, shift rail, etc.
