Wiseco RED Series Ford Small Block 4.060in Bore 1.090in CH -5.00 CC Piston Set

If you're building a performance Ford Small Block engine, this Wiseco RED Series piston set is designed to handle the demands of racing and power adder applications. These pistons are forged from 2618 aluminum, a material chosen for its high tensile strength, which is crucial for engines that see extreme stress. The RED series stands for Race Engineered Design, meaning Wiseco has focused on creating a piston that offers both the durability needed for competition and the precision machining that gives you a competitive edge on the track.

Wiseco machines these pistons in the USA, and they've incorporated several features to ensure longevity and performance. The horizontal slot oiling in the wrist pin bores is a smart touch that keeps the wrist pin and the small end of the connecting rod properly lubricated, which is vital for preventing premature wear. Dedicated forgings are used for each specific engine application, allowing for an optimized strutted design that maximizes strength while keeping weight down. You'll also find an accumulator groove, which helps maintain consistent ring seal and power delivery. Plus, each set comes complete with premium rings, so you won't have to source those separately.

The skirt coating, called ArmorGlide, is another detail that makes a difference. It's designed to reduce friction and noise during operation, which also helps to minimize wear on the piston skirt and cylinder walls. These pistons have a 4.060-inch bore and a -5.00cc dish, with a compression height of 1.090 inches and a 0.927-inch pin diameter. Keep in mind that these are not CARB approved and cannot be shipped to California.
