Accessory Clamp 1-3/4in w/ through hole

The Allstar Performance Accessory Clamp 1-3/4in with through hole is an essential fastening component designed for securing hoses, cables, and fluid lines in high-performance automotive applications. Whether you're building a custom engine bay, installing a rollcage coolant line, or routing fuel lines on a race car, this clamp provides reliable vibration-resistant mounting where precision matters. Mechanics and fabricators rely on this clamp across street rods, performance builds, and competition vehicles where factory routing won't work and custom runs demand professional-grade hardware.

Built to Allstar Performance's exacting standards, the 1-3/4-inch clamp diameter accommodates tubing and hoses in that size range with a through-hole design that allows you to bolt it directly to brackets, frame rails, or firewall-mounted tabs using a single fastener. The through-hole construction eliminates the need for separate mounting hardware and ensures the clamp won't slip under engine vibration—critical when routing coolant to auxiliary coolers, braided fuel lines to carburetors, or vacuum lines through tight engine compartments. Lightweight at just 0.13 lbs, this clamp adds negligible mass while delivering the clamping force and durability expected from Allstar's competition-proven product line.

This clamp suits custom builders, race teams, and restoration enthusiasts who demand professional routing and secure line management in modified or race-prepped vehicles. The through-hole mounting works with standard bolt sizes and integrates seamlessly into existing bracket systems or allows you to fabricate simple mounting tabs from mild steel or aluminum. Install multiple clamps along a run to isolate vibration and prevent chafing—a best practice that extends hose life and prevents coolant or fuel leaks under sustained high-RPM operation. Ideal for street rods, drag cars, circle-track vehicles, and any engine build where reliability and clean routing are non-negotiable.
