Wiseco RED Series Ford Small Block 4.020in Bore 1.165in CH -5.00 CC Piston Set

These Wiseco RED Series pistons start with a dedicated forging from 2618 aluminum, chosen for its high tensile strength, which is essential for the demanding conditions found in performance racing and engines with power adders. The Race Engineered Design (RED) philosophy means these pistons aren't just strong; they're precisely machined to give you a competitive edge on the track, whether you're in drag racing or circle track applications.

You'll find horizontal slot oiling in the pin bores, a detail that keeps the wrist pin and small-end of the connecting rod properly lubricated, which is critical for ensuring a long service life. The strutted design is optimized for specific engines, balancing strength with weight to maximize performance. Plus, the ArmorGlide skirt coating is a smart touch that helps reduce friction and noise, while also minimizing wear on both the piston skirt and the cylinder wall. This set includes premium rings, so you won't need to source those separately, and an accumulator groove is included to help maintain consistent ring seal and power delivery.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
