🔧 About the TSK49-B Bearing

The TSK49-B is an oversized, precision-engineered release bearing designed exclusively for use with the TSK49 stainless steel transmission sleeve.
It replaces the OEM release bearing and provides increased durability, smoother operation, and improved longevity when paired with the upgraded sleeve.

Key Features:

• Oversized internal diameter (sleeve-specific fitment)

• Heat-treated and hardened bearing race

• High-load ball bearing assembly

• Engineered for both push-type and pull-type clutch applications supported by TSK49

• Reduces vibration, noise, drag, and misalignment

• Designed for harsh conditions and high-load clutch systems

💪 What the TSK49-B Bearing Fixes

• Release bearing noise

• Clutch pedal vibration

• Chatter during engagement

• Heat-based bearing degradation

• Sticky or inconsistent clutch feel

• Wear caused by damaged or worn OEM aluminum transmission snouts

⚠️ Important Installation Notes

• This bearing must be used with the TSK49 stainless steel sleeve. It will NOT fit the factory aluminum snout.

• Use only the high-temperature grease supplied with the TSK49 kit.

• Replace the bearing clip if included with the associated sleeve kit.

🛡️ Advantages of the TSK49-B Over OEM

• Designed for use on a hardened steel surface rather than bare aluminum

• Provides improved alignment and smoother clutch operation

• Prevents repeat failures caused by OEM snout wear

• Extends transmission and clutch system lifespan

• Ideal for heavy-duty use, towing, and off-road applications
