Piston Ring Set 4.030 Gapls 2nd 5/64 5/64 3/16

The TOTAL SEAL Piston Ring Set 4.030 Gapls 2nd 5/64 5/64 3/16 represents precision engine internals engineered for high-performance and competition builds where reliability under extreme conditions is non-negotiable. Built to OEM or better tolerances, this ring set is designed for operators and builders who demand components that withstand sustained high-load cycles. Whether you're rebuilding a duty engine or assembling a precision long-range platform, Total Seal's reputation in motorsports and industrial applications translates directly to dependable thermal sealing and minimal blowby.

The 4.030-inch bore specification indicates this set targets modern large-displacement engines requiring minimal ring gap for optimal compression and gas sealing. The "Gapls" (gapless) design eliminates the conventional end-gap weakness, reducing combustion bypass and improving sealing efficiency across the full operating RPM range. The 2nd ring designation (5/64-inch width) and oil ring specification (5/64 5/64 3/16) follow Total Seal's proprietary chemistry and coatings that reduce friction while maximizing ring-to-wall contact pressure. This configuration minimizes oil consumption and maintains consistent cylinder pressure during both steady-state and transient load conditions—critical for mission-critical engine reliability.

This piston ring set is ideal for engine builders, machine shops, and performance platforms requiring bespoke internal components. Installation requires precision honing and professional assembly to realize the full thermal and sealing benefits; improper ring installation or bore preparation will compromise performance. Verify your engine's exact bore diameter and stroke specifications before ordering—Total Seal manufactures rings to exact tolerances, and any mismatch will result in poor sealing or catastrophic failure. Weighing 0.84 lbs, this compact set delivers measurable improvements in compression retention and longevity for engines operating in demanding duty cycles.
