Stroker Kits - Done Right

VPE Vigilante Engine Kits are available in various displacements and are suitable for stock or aftermarket blocks, consisting of 4340 Steel H-Beam Connecting Rods, a 4340 Forged Steel Crankshaft and Probe SRS Series 2618-t6 Forged Pistons. Most feature Nitride Steel Top/Napier Second Ring Sets. They are perfectly suited for stock replacement applications, or they can be set up with boost or increased compression for high performance street or street and strip combinations.

The longest rod feasible is utilized in each instance, which gains the maximum piston to counterweight and rod bolt to camshaft clearance possible, as well as decreased piston weight.

Altered stroke and/or compression ratios are not legal for use in emissions controlled vehicles.
