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.
