TSK4 (Transmission Sleeve Kit) for 2004-2021 SUBARU STI 6 SPEED Replaces 30502AA130
The SUMO Transmission Sleeve Kit (TSK) is the only logical solution to repair the damage caused by the throw out / clutch release bearing riding on the transmission case extension. Symptoms of this are noticeable clutch chatter, excessive noise, a sticky pedal, rough pedal travel, and premature or early replacement of clutch components. In the past the only real way to repair this was to replace the damaged or worn transmission case. All this really does is, start the process over again on a new surface. The SUMO TSK addresses the problem at the source, the soft surface. By providing the throw out bearing a new durable long-lasting stainless steel surface to ride on we not only treat the symptoms but we cure the problem for good.
