Accessory Clamp 1in w/ through hole

The Accessory Clamp 1in with through hole from Allstar Performance is a precision fastening component designed for engine builders, fabricators, and automotive enthusiasts who demand reliability in high-vibration environments. This clamp secures hoses, cables, wiring harnesses, and accessories to engine blocks, frame rails, and chassis components where vibration isolation and secure mounting are critical. Whether you're building a street engine, race car, or restoration project, a quality 1-inch clamp with through-hole design prevents rattles, chafing, and component failure that can compromise engine performance or create safety hazards.

Engineered by Allstar Performance—a trusted name in motorsports and engine components—this clamp features a 1-inch diameter accommodation suitable for standard hoses and tubing used in cooling systems, fuel lines, and accessory circuits. The through-hole design allows direct bolt-down mounting to engine blocks or frame using Grade 8 hardware, eliminating the need for separate bracket fabrication and ensuring rigid, vibration-resistant clamping. The compact 4 x 0.75 x 7-inch footprint accommodates tight engine bay layouts without interfering with adjacent components, while the robust construction withstands thermal cycling and mechanical shock inherent to high-performance and heavy-duty applications.

This clamp is essential for engine rebuild kits, performance upgrade packages, and custom fabrication projects where stock clamps are unavailable or undersized. Mechanics and fabricators rely on Allstar clamps to secure brake lines, fuel lines, coolant hoses, and wiring harnesses during engine swaps, turbo installations, and complete restorations. The lightweight design (0.15 lbs) adds negligible weight while providing maximum holding force, making it ideal for both street and competition builds. Installation requires only a single bolt through the provided hole, reducing assembly time and labor costs on any project requiring durable, repeatable fastening solutions.
