The PDM TSK3 Subaru Snout Throwout Bearing TOB Sleeve Repair Kit is a permanent, professionally engineered solution designed to eliminate this common Subaru failure point. Instead of relying on the factory aluminum snout, the TSK3 installs a precision-machined stainless steel sleeve over the transmission snout, creating a hardened and perfectly smooth surface for the throwout bearing to operate on. This stops wear at the source and dramatically improves long-term clutch reliability. This transmission sleeve kit from PDM eliminates that problem and will save you from having to replace your Subaru's transmission case as long as there is 3/4" of material left to anchor the sleeve to.
Subaru push style manual transmissions are well known for premature wear of the factory aluminum throwout bearing snout (also referred to as the quill). Over time, the clutch release bearing rides directly on this soft aluminum surface, causing grooves, uneven wear, clutch chatter, vibration, noise, and ultimately poor clutch disengagement. Left unaddressed, this wear can lead to costly transmission case damage or repeated clutch failures.
Unlike temporary fixes or repeated bearing replacements, the PDM sleeve restores proper clutch geometry and engagement while preventing future damage. It is engineered for push-type Subaru manual transmissions and installs easily during a clutch service without modifying the transmission case. Whether your vehicle is a daily driver, track car, or high-horsepower build with an upgraded clutch, the TSK3 provides peace of mind and long-term durability.
The PDM USA Tranquil kit delivers significant real-world performance and reliability improvements that directly impact drivability:
High-power Subarus or vehicles with upgraded clutches, these improvements translate into better control, predictability, and reduced maintenance over time.
Vehicle must use a push-style clutch system and have sufficient remaining snout material for sleeve installation.
