Distributor Slip Collar

The MOROSO Distributor Slip Collar (MPN 26217) is a precision-engineered bolt-mounted collar designed for Chevrolet V6 and V8 engine platforms. Built for engine builders, mechanics, and automotive enthusiasts who demand OEM-grade component retention, this distributor collar secures critical ignition timing components with adjustable positioning. The slip collar design allows fine-tuning of distributor alignment without permanent modification, making it essential for performance tuning, engine swaps, and factory restoration work.

Manufactured from hardened steel with a corrosion-resistant finish, the distributor slip collar weighs just 0.18 lbs and measures 3.7 x 0.7 x 5.1 inches, ensuring minimal engine bay footprint while maintaining structural integrity under vibration and thermal cycling. The bolt-mounted design integrates seamlessly with Chevy engine blocks, providing stable clamp pressure that prevents distributor walk—a common cause of ignition timing drift in high-RPM and modified applications. Adjustable tension allows technicians to dial in precise rotor-to-cap clearance and optimal spark delivery timing without costly machine work.

This collar is indispensable for Chevrolet small-block and big-block V6/V8 engines, particularly in street performance, racing, and classic car restoration where timing consistency directly impacts horsepower and fuel efficiency. Technicians rebuilding carbureted or early fuel-injected Chevy platforms will find the adjustable slip design far superior to fixed collars when compensating for wear or establishing baseline ignition geometry. Installation requires standard hand tools and basic mechanical knowledge; compatibility is universal across Chevy V-series engine families that utilize traditional external-cap distributors.
