Belt 25mm BBC +.250/ +.400 Raised Cam

The Belt 25mm BBC +.250/+.400 Raised Cam (MPN: BEL-31060) is a precision timing belt designed for Big Block Chevy engine applications. It is essential for engine builders who require exact synchronization between crankshaft and camshaft rotation, particularly in performance and stroker builds that deviate from stock cam timing geometry.

This 25mm-wide belt accommodates raised cam installations with both +.250 and +.400 lift specifications. The unique geometry of raised cams necessitates a belt that ensures proper tooth engagement and consistent tension, critical for maintaining valve timing accuracy in high-performance applications. Using standard timing belts can lead to issues such as belt skip or accelerated wear.

Engine builders restoring or constructing Big Block Chevy engines for street performance, drag racing, or marine applications will find this timing belt indispensable. It is specifically matched to their cam geometry, preventing timing slip that can result in inconsistent idle quality and power loss. Proper fitment is ensured with the belt's dimensions, making it a reliable choice for high-performance engine setups.
