Crank Support Assm. SBC Counter Balance

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.

These crankshaft snout supports feature a unique hub which is completely machined from two pieces of heat treated chromoly steel billet. This insures that the end where the bearing mounts will run true with the end of the crankshaft.

The hub also has dual .250" keyways on both ends so that the front can be used to drive another accessory such as a oil pump or starter jaw. The aluminum bracket and stand assembly that hold the front bearing mounts to either the front of the block or the front cover, depending on application.

Kits include crank hub, mounting plates, stands, bearing, and hardware. Fits 383,400 and most other aftermarket small block Chevy engine combinations that are externally balanced.

Crank shaft supports are generally meant for competition use only with no provision for altenators but can be adapted by the customer if they so desire.
