Summit Racing™ Pro LS Forged Pistons

The Summit Racing Pro LS forged pistons are affordable and built to withstand the rigors of high boost and nitrous. These pistons are forged from Premium 2618 alloy - the strongest made. They have specially profiled piston skirts, which allow them to run a tight piston-to wall-clearance for maximum ring seal and minimal friction. They have many other high-tech features too!

• Maximum ring-land thickness for power-adders
• Dedicated forgings for the best strength-to-weight ratio
• Multiple compression ratios specifically targeted for 4.8L, 5.3L, 5.7L, and
6.0L engines
• Designed around Premium file fit rings with Gas-Nitride or Plasma steel tops
and ductile Napier second rings
• Available in versions for Gen. 3 Press-fit, Gen. 4 Floating, and Aftermarket
6.125 rods
• Standard and Stroker versions available
• Generous valve reliefs that work with both Cathedral port AND Rectangle
port heads
• Pressure-fed pin-oiling
• Pressure seal groove in 2nd ring land for increased seal.
• High-Speed brush deburring to remove sharp edges that cause detonation
• Ultra-Modern 2.250 pin forgings clear the reluctor rings with stroker cranks
• Durable Chromium Steel wristpins.
• Replacement Singles Available
