The RockJock III high-pinion 60 rear end features 5.13 gears and a Detroit Locker. A Currie disc brake kit includes a nifty drum emergency brake. The Currie track bar is adjustable and the bracket on the housing has four mounting holes so you can dial-in your track bar perfectly. We mentioned that the Walker Evans Racing shocks have fourteen compression adjustments. Rebound valving seems to be just about perfect, too. Note the Kilby canister relocater that mounts the vapor canister out of harm's way.
