Tappet,Hyd Big Axle Std Od Pan & Shovelhead 1953/Later Rpls Hd 18522-53 Jims 2462-1Jims offers you a choice of four different types of Big Axle Tappet Assemblies. The first type is the Standard Style Mechanical Tappet. The second type is the Standard Style Hydraulic Tappet. The third type is the Powerglide Hydraulic Tappet and the fourth type is the Hydrosolid Tappet. All assemblies listed are of the Big Axle Roller design.

The Big Axle Tappet has a 27% greater wall that reduces harmonic distortion for better tracking of the cam lobe.
