Description
We have redesigned and expanded our GM LS1 series product lines! These new pistons utilized our dedicated Forged Side Relief (FSR) forging that was specifically designed for high output GM LS1 series engines. In addition we have found ways to reduce weight and maintain the durability needed for both street and racing use. Lightweight and extremely durable, these pistons are machined for 1.5mm, 1.5mm, 3.0mm rings. Wrist pin upgrade recommended above 800hp.
