Chevy Standard & Tall deck Lower Drive +1" w/slip-collar

Extra 1" altitude for the mag provided with this drive. Due to the slip collar, this drive works with standard and tall deck Chevy engines. Improvement for 2025! We've just redesigned all our Chevy drives to utilize a spring-lip shaft seal in the top of the drive. No more engine oil migrating up the drive into the top section. Includes a new stainless steel/quick-release band clamp, a cross driver, timing pointer, and gasket...a complete drive setup in one box! Use the drop down menu above to add flying magnets and a hall-effect sensor to your new drive! It generates a perfect tach signal (12VDC required) for RPM switches, rev limiters, data loggers, etc. This drive also works with mag 12 and 20 using our drive adapter found HERE. The "H" dimension for this drive is: 4-3/8" (STD deck) and 3-5/8" (Tall deck)
