Manufactured by Wiseco, ProTru Pistons are forged and affordable with features usually only found in more expensive pistons. Wiseco Pro Tru Kits include pistons and wrist pins. Ideal for racers on a tight budget. The pistons feature CNC-machined domes, oversized valve pockets for use with larger diameter valves and higher lift camshafts, and precision-reamed, pressure-fed wrist pin oiling holes. Last but not least, the wrist pins are made from chromemoly for long-lasting strength, and include a set of Spiro locks.
