2 Bolt Clamp On Retainer 1.75in Wide

The 2 Bolt Clamp On Retainer 1.75in Wide by Allstar Performance is an essential fastening solution for engine builders, restoration shops, and serious DIY mechanics tackling high-performance applications. This clamp-on retainer secures critical engine components—particularly fuel lines, hoses, and wiring bundles—during assembly and operation, preventing vibration-induced loosening and catastrophic failures on the dyno or track. Whether you're building a street engine, race motor, or restoring a classic, this retention system keeps your plumbing organized and failure-proof.

Engineered for durability and consistent clamping force, the 1.75-inch wide clamp jaw distributes pressure evenly across tubing or hose outer diameters, minimizing deformation while maximizing grip. The two-bolt design provides redundant fastening security—if one fastener loosens, the second retains the bundle—a critical redundancy in high-vibration environments like engine bays. The robust construction handles thermal cycling and mechanical shock without stress-cracking or slippage, making it ideal for both naturally aspirated and forced-induction builds.

This retainer fits seamlessly into Allstar Performance's comprehensive engine assembly ecosystem, serving builders who demand industrial-grade reliability over budget alternatives. Installation requires standard metric or SAE hardware (fasteners sold separately) and works with fuel line, coolant hose, braided stainless, and rubber tubing in the 1.75-inch width range. Mechanics frequently specify this clamp for carbureted builds, EFI conversions, and race-prepped engines where vibration isolation and repeatability matter most. Compact dimensions (8 x 2 x 11.1 inches) and 1.93-pound weight make it easy to position in tight engine compartments without adding structural burden.
