22-1/2in Dry Sump Belt

The 22-1/2in Dry Sump Belt from Stock Car Products is a precision-engineered serpentine belt designed for high-performance dry sump lubrication systems in race engines and heavily modified vehicles. Built by a trusted manufacturer of oil pump drive components, this belt transfers rotational power from the crankshaft to your dry sump pump with minimal slippage and maximum reliability during sustained high-RPM operation. Whether you're running a full dry sump conversion on a track car, a street performance build, or a dedicated race platform, this belt ensures consistent oil circulation when traditional wet-sump systems fail or cannot deliver adequate flow.

This Gilmer drive belt measures 22.5 inches in length with a 1-inch width and 3/8-inch pitch profile, dimensions that define compatibility with specific dry sump pump pulley ratios and crankshaft balancer configurations common in modified engine builds. The Gilmer tooth profile—also called HTD (High Torque Drive)—provides superior grip and load distribution compared to standard V-belts, critical when transferring the continuous torque demands of a dry sump pump at elevated engine speeds. The compact 0.14-pound weight reflects a well-designed component engineered for minimal rotational mass, reducing parasitic losses and allowing your engine to focus power toward propulsion rather than belt drive inefficiency.

Mechanics and engine builders installing or upgrading dry sump systems will find this belt essential for maintaining consistent oil delivery under load. Installation requires alignment with OEM or custom pulley sets sized for 22.5-inch belt length; verify your specific dry sump kit's belt specification and crankshaft pulley diameter before ordering. This belt is suitable for carbureted and fuel-injected applications alike, works across normally aspirated and forced-induction builds, and delivers the reliability expected in competition and high-output street engines where conventional lubrication falls short.
