With the supercharger belt pulling the crank snout upwards, and the first two piston and rod assembles pressing downward, this area of the crankshaft is in need of some additional support. By adding a crank snout support, in essence a sixth main bearing, the vulnerable unsupported snout has less chance of bending and breaking.
Race engines, especially those prone to detonation, are the applications most in need of this support. The aluminum bracket and stand assembly that hold the front bearing mounts to the front of the block off the four 7/16" bolt holes.
Kits include mounting plates, stands, sealed ball bearing and mounting hardware. Fits 396, 402, 427, 454, Donovan, World, CN and most other aftermarket big block Chevy engine combinations.
Crank supports are designed for competition use and have no provision for an alternator.
THIS IS JUST THE CRANK SUPPORT CRADLE ASSM. IF COMPLETE KIT IS WANTED CHECK OUT PART NUMBER #2310-0002F.
