IMPROVED - Chevy Standard deck "Shorty" Lower Drive w/ CROSS

This drive works with any standard deck Chevy. This is the "Shorty" drive that has minimal clearance between the bowl and the clamp flange. 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. Since we're building these drives now instead of Mallory, we've made a design change that everyone will like. Instead of the pins and rubber coupler to join the mag to the drive, we've gone to the popular, proven cross arrangement. The drive now contains a steel female cross welded to the high-strength shaft. We've also included a new aluminum cross and hardware for the mag. Eventually, we'll make all the drives like this. For now, we offer a few models with this improvement and this is one of them. Includes a new stainless steel/quick-release band clamp, aluminum magneto cross and hardware, 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, 20 and 44. The "H" dimension for this drive is: 2-7/8
