HP GM Distributor w/ Slip Collar

The HP GM Distributor with Slip Collar from ALLSTAR PERFORMANCE is a precision ignition component engineered for small-block and big-block Chevrolet engine builds. This distributor serves as the heart of your ignition system, synchronizing spark delivery across all cylinders with mechanical accuracy. Whether you're building a street performance engine, restoration project, or competition platform, a quality distributor is non-negotiable for reliable starts, smooth idle, and predictable power delivery under load.

The slip collar design is a hallmark of premium distributor construction, allowing smooth, wear-resistant engagement with the engine's distributor drive gear while permitting controlled rotational tolerances. This feature reduces binding during installation and accommodates minor variations in deck height or block machining—critical when you're working with older blocks or custom machine work. The HP-grade housing and internal components are optimized for high-rpm stability and consistent spark timing, resisting centrifugal drift that plagues lesser units. Compact dimensions (6.25 x 6 x 17.5 inches) ensure compatibility with tight engine compartments, while the 4.95 lb weight keeps rotating mass minimal for better engine response.

Mechanics and engine builders rely on ALLSTAR distributors for restorations, crate engine installations, and high-output street machines where OEM replacements fall short. The slip collar design is particularly valued when reinstalling a distributor multiple times during tuning or when swapping blocks. This distributor pairs seamlessly with traditional points-based or modern electronic ignition systems, making it ideal for both classic builds and contemporary performance applications. Proper installation requires indexing the rotor to cylinder one and confirming ignition timing with a timing light—standard procedure that ensures maximum combustion efficiency and engine longevity.
