Release Bearing Hyd. Ultra Low Profile

The Release Bearing Hydraulic Ultra Low Profile by Tilton (MPN 61-8122) is a precision clutch component engineered for high-performance vehicles requiring compact, space-constrained engine bays or heavily modified drivetrain packages. Built for racers, drift competitors, and street performance enthusiasts, this hydraulic release bearing eliminates the mechanical disadvantages of conventional cable or rod-actuated systems by delivering consistent, linear clutch disengagement through fluid pressure. The ultra-low profile design allows fitment in applications where traditional release bearings create packaging conflicts, making it ideal for turbocharged builds, engine swaps, and competition-level clutch upgrades.

This hydraulic release bearing operates by converting input pressure from a master cylinder directly into bearing actuation, eliminating play and improving pedal feel compared to mechanical linkage systems. Tilton's ultra-low profile geometry minimizes protrusion into the bell housing, reducing overall length while maintaining full load capacity—critical for vehicles with tight transmission tunnels or modified firewall setups. The compact 6.15" × 4.45" × 6.8" footprint and lightweight 1.04 lbs construction preserve suspension geometry and reduce unsprung mass. Hydraulic actuation provides superior modulation during aggressive launches, downshifting, and sustained performance driving, while eliminating cable stretch and mechanical wear that compromise shift quality over time.

This release bearing benefits track-focused drivers, LS or Coyote engine swap builders, and anyone running a high-clamp-load performance clutch requiring stable, repeatable disengagement under racing conditions. Installation requires a compatible hydraulic clutch master cylinder and hardline routing from the transmission bell housing, making it best suited for full rebuild situations rather than bolt-on upgrades to stock systems. Verify bell housing bore diameter and master cylinder compatibility with your specific vehicle platform before ordering—Tilton components are engineered as system solutions, not universal drop-ins. Those seeking to eliminate cable slop, reduce clutch modulation delay, or fit compact clutch assemblies in tight engine bays will find this ultra-low profile hydraulic release bearing an essential upgrade.
