- Total Seal Gapless Max Seal Piston Rings
Gaps open as standard piston rings wear, allowing more combustion gases to escape (blow-by). Total Seal Gapless rings solve this problem with two-part interlocking rings to close gaps and to improve piston-cylinder seals. As gapless rings wear, the gaps stay sealed giving you better over all performance that lasts.
Features:
- Ideal For Naturally Aspirated, Forced Induction, Or Mild Nitrous Applications (Such As Hot Street, Drag & Road Race, Circle & Dirt Track, Tractor Pull)
- Provides Increased Horsepower & a Wider Torque Curve
- Gives You 5" to 6" in./lbs More Engine Vacuum
- Allows For Better Oil Control
