Crank Supports

Per NHRA

One of the biggest changes for 2007 is the addition of a new rule regarding the clutch/crank support.

 

            A clutch/crank support is mandatory on any car running 9.99 or quicker and is accepted on any vehicle. The clutch-side crank-support bracket and bottom plate must be made of minimum .350-inch-thick aluminum at its thinnest point. The clutch/crank-support bracket must be connected using either three 5/16-inch bolts or four 1/4-inch bolts to the bottom plate.


Amend's crank supports are CNC machined from a special aluminum alloy plate that provides a combination of high strength, high fracture toughness and good resistance to fatigue crack propagation at high stress levels.  The crank supports are then polished with a high energy finishing machine to remove stress risers and to give the crank supports a durable polished finish.  We do carry these in stock for immediate delivery.
