Tilton’s 4300-Series hydraulic release bearings feature a 38mm (1.50″) radius-face contact diameter bearing for use with flat-finger clutch diaphragm springs. Designed for use with Tilton 4.5” & 5.5” clutches, and suitable for use with many non-Tilton 4.5” & 5.5″ clutches, the 4300-Series hydraulic release bearings are designed to be bulkhead mounted inside transmission/bellhousing.
Superior lightweight aluminum construction
Tilton HRBs are designed, machined, assembled and checked by Quality Control at Tilton’s headquarters before they are approved and shipped. By using the highest quality materials, combined with the latest machining methods, our designs can be light, strong, and provide race-proven results, time and time again.
Proprietary low-friction surface treatments
Using the latest technologies, Tilton HRBs are treated with a durable, low-friction coating, created specifically for our use on HRBs. This coating aids in the long-wearing durability and high-performance they are known for.
Unique monoseal technology
For proper seal tension, Tilton has created a unique multi-edged quad-tension seal, to ensure consistent feel, long term wearability, and lasting reliability. Seals have been tested to hundreds of thousands of actuations without failure, which is why this technology is built into every Tilton HRB.
Wiper-seal debris prevention
The resilient orange seal is your guard against unwanted HRB bore damage.
Smooth and reliable high-quality bearings
Using the highest quality components, Tilton bearings are tested extensively for long life durability.
Constant contact design
Coupling high-quality, durable bearings with a constant contact design, your system is always ready to engage.
As your clutch wears, Tilton HRBs compensate to maintain the same pedal feel, shift after shift.
