CP Pistons Rod Set BRS 4.135 Bore 4.125 Stroke Chevy LS7

Replacement pistons and connecting rods for Chevrolet LS7 engines — CP Piston BRS Chevy LS7 4.135 Bore 4.125 Stroke 6.125 Rod Set Of 8 (MTO Non-Cancel) provide precise dimensional control to support accurate engine assembly and predictable mechanical tolerance management.

CP Pistons engineering is reflected in the explicit dimensions and kit configuration; dimensions are stated to ensure correct matching to block and crank specifications during build or rebuild.

• 4.135" Bore — Specifies the piston crown diameter to align with a 4.135-inch cylinder bore; this dimension is necessary for correct piston-to-cylinder clearance and compression height considerations during assembly.
• 4.125" Stroke — Defines the crankshaft throw used to calculate engine displacement and piston travel; maintaining the stated stroke ensures the assembled reciprocating motion matches intended engine geometry.
• 6.125" Rod — Indicates the connecting rod center-to-center length; correct rod length is critical for piston dwell, connecting-rod angularity, and final rod-to-stroke ratio when building the LS7 rotating assembly.
• Set of 8 — Complete eight-cylinder kit supplied as one matched set to ensure balanced mechanical dimensions across all cylinders for uniform operation.
• MTO Non-Cancel — Made-to-order status is indicated in the title; ordered kits are produced per order and are non-cancelable once manufacturing begins.

This description focuses on measurable, assembly-relevant details so engine builders and technicians can verify compatibility with their LS7 block, crank, and bearing choices. Use the supplied dimensional data to confirm clearances, compression height, and rod/stroke relationships before installation.

Package scope

• 8 pistons and connecting rods (set of 8)
