Racetec / Autotec Forged Pistons

RaceTec's AutoTec Cleveland forged pistons are high-quality with precision machining and a great price. AutoTec pistons are manufactured from the low expansion, high wear, high silicone  4032 grade aluminum alloy. These Forged Cleveland pistons with the 4032 Forging, have excellent wear resistance with a low expansion rate and are extremly durable and long lasting. Best of all they are very low in friction and run a tighter piston to bore clearance which results in a quieter piston operation, especially on cold start ups. 

Manufactured on forged side relief, 4032 low expansion, high silicon material excellent for street or strip applications. Has precision Diamond turned skirts.
