86.00mm Ring Compressor

The 86.00mm Ring Compressor by ARP is an essential tool for engine builders and mechanics engaged in piston ring installation during engine assembly or rebuild. This precision instrument compresses piston rings to their smallest diameter, allowing safe insertion into cylinder bores without scoring or damaging the delicate ring grooves. Whether you're rebuilding a high-performance engine or restoring a classic vehicle, this tool is crucial for ensuring proper ring seating during engine startup.

ARP's 86.00mm ring compressor features precision-engineered construction designed to grip and compress standard piston rings uniformly without binding or creating stress concentrations. The robust design minimizes deflection during the compression stroke, which is critical for preventing ring breakage or uneven compression that could cause installation damage. This ensures consistent band tension and smooth operation, reducing installation time while protecting expensive pistons and rings from costly mistakes.

This ring compressor is ideal for engine builders, machine shops, and serious DIY enthusiasts specifically working on applications with 86mm bore specifications. Its design is tailored for mid-range engine applications common in automotive restoration and modification work, making it a valuable addition to any mechanic's toolkit.
