Vivid Racing Type RA Gearset Subaru WRX 02-07

In Stock and Ready to Ship

Vivid Racing gearsets come complete and ready to install in any WRX gearbox. Non-turbo applications can also utilize these sets but require an additional adapter kit. This is the least expensive way to substantially increase the reliability of the WRX gearbox. The Type RA 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 RA Sets include: main shaft & all forward gears, shaft lock nuts, front oil seal, 3rd/4th shift rail, 3rd/4th synchro hub, 4th synchro ring, 3.90 speedometer gear, and rear case gasket.
