Finally! An affordable alternative to the STi 6 speed tranny. Genuine Subaru RA Gearsets - Cryoed!
For A Stock Check!!
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.
Gearset kits 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, rear case gasket.
Rebuild time is generally 5-6 hours of bench time (not including removal & installation) and if your transmission is damaged we HIGHLY recommend new bearings and synchros.
(Ratios -- 3.083 / 2.062 / 1.545 / 1.151 / 0.825)
