4 Bolt Clamp On Retainer 3in Wide

The ALLSTAR PERFORMANCE 4 Bolt Clamp On Retainer 3in Wide is a two-piece steel clamp-on ring engineered for high-vibration automotive and motorsports applications. With a 3-inch inner diameter and 3-inch width, this retainer uses four bolts to deliver secure, repeatable clamping force across demanding operating conditions. The natural steel finish and proven clamp-on design make this component a trusted choice for engine builders, fabricators, and technicians who require precision holding without permanent modification to the base component.

The four-bolt configuration distributes clamping load evenly across the clamp diameter, reducing point stress and vibration-induced loosening common in single or dual-bolt designs. The two-piece construction allows rapid installation and removal without full component disassembly. Steel construction delivers the rigidity and temperature stability required in engine compartments and high-heat zones where aluminum would creep under sustained load. At 3.42 lbs, the retainer is substantial enough to handle serious duty while remaining manageable for shop use and field service.

This clamp retainer is suited for engine supply line retention, coolant hose management, exhaust component positioning, and any application requiring a reusable, non-destructive clamping solution. Shops working with engine swaps, restorations, and custom fabrication benefit from the repeatability and adjustability of clamp-on design. The natural finish is compatible with most fluids and coolants found in automotive service; however, operators in corrosive or salt-air environments should assess protection needs. ALLSTAR PERFORMANCE's retainer systems are widely recognized in the engine building and race engine communities for holding up to sustained vibration and thermal cycling.
