Wiseco Piston Pin Locks & Clips from IPD Racing — 3 part numbers in stock and shipping from our Texas warehouse. Popular fitments here include 15mm Round Wire Locks, 12mm Round Wire Locks, 10mm Round Wire Locks. Wiseco has forged its own pistons in Mentor, Ohio since 1941, and every part in this category is built for engines that get used hard, not babied. Round wire locks in 10mm through 17mm. Never reuse a wire lock: it takes a set when it is installed, and a lock that walks out of its groove destroys the cylinder, the piston and usually the head with it.
