Relay Holder Kit

The Relay Holder Kit is an essential mounting solution for builders and tuners who demand clean, organized engine bay wiring harnesses. Designed for performance vehicles running aftermarket fuel management systems, this compact holder secures relays in a fixed position, preventing vibration-induced connector loosening and electrical issues that can arise in high-performance builds.

This relay holder kit accommodates standard automotive relay form factors and features precision-engineered indexing to prevent accidental dislodging during acceleration, cornering, or vibration cycles. Its compact footprint—measuring just 1.5 × 1.5 × 3.5 inches—integrates seamlessly into tight engine bays without occupying valuable space needed for other components. Weighing only 0.05 lbs, the kit provides the structural rigidity necessary to maintain consistent electrical contact under extreme conditions.

Professional tuners, performance shops, and DIY enthusiasts will appreciate the reliability this kit brings to their builds. Proper relay mounting eliminates a common source of intermittent fuel system faults that can be notoriously difficult to diagnose, making it an ideal choice for serious tuners who understand the importance of electrical reliability in fuel delivery precision and overall engine performance.
