Whether you're planning an 800hp street build or a 1700hp drag monster, each rotating kit is tailored to your bore, stroke, and piston volume.

Kits include coated tri-metal main and rod bearings, plus piston rings selected to suit your target power range.

Choose the right setup for your LS project:

Build Tip: Pair with a camshaft and heads matched to your power level. The 800hp setup is great for naturally aspirated street builds, while the 1700hp combo is ideal for boosted drag racing.

Installation Notes: Bearing clearances and ring gaps must be checked and set by a professional engine builder. We are not liable for damage from incorrect assembly or mismatched components.

Sales Policy: Rotating assemblies are custom-built and non-returnable. All sales are final—please verify your specs before ordering.
