Do you need to hold more power put cannot afford the STI 6-speed transmission?
Don't want the inconveniences of a dog-box or the price?
Looking for a more track friendly gear ratio?
Then our STI RA gear-set is the perfect solution for you!
The STI RA V6 gears are a found in the rally-bred Version 6 Impreza STI RA and is designed to be a much beefier swap for your WRX 5-speed transmission.
The thicker gear teeth as well as the inherently stronger gears and shaft are a perfect solution for customers looking for gear-sets that will hold more power.
For further strengthening all gear-sets are CRYOGENICALLY TREATED.
We recommend these gear-sets for customers looking for gear-sets to hold 275-350awhp.
For higher power levels we would recommend either a STI 6-speed tranny or a synchroless dog-box.
All gearset kits include STI RA Gears 1-5, main shaft, properly matched speed-o gear, and shifter fork.
Please see our bearing and synchro sections for a complete rebuild kit.
Rebuild time is generally 5-6 hours of bench time (not including removal & installation) and if your transmission is damaged will usually require new bearings and synchros.
