Product Summary

The Powerbuilt PBT940387 Piston Ring Compressor Set is a must-have for professional mechanics and engine rebuilders tackling piston installation jobs. Designed to compress piston rings for safe, damage-free installation into engine cylinders, this set provides the precision, durability, and versatility needed for a wide range of engine types. This 7-piece set includes six band-style ring compressors covering bore sizes from 2-7/8in. to 4-3/8in., accommodating a broad spectrum of engines—from small block to big block and import to domestic. Each band is constructed from heavy-duty spring steel, ensuring even compression and consistent tension around the piston for reliable performance. The included ratcheting compressor pliers offer fast, secure tightening and easy release once the piston is in position. Whether you're working on a full rebuild, replacing pistons, or restoring performance, this kit helps prevent broken rings, scuffed cylinder walls, and costly do-overs. Stored in a durable blow-molded case, the set keeps each band clearly labeled and organized for quick access in the shop or garage. Trust Powerbuilt to deliver quality and precision on every piston installation job.
