ARP 901-8400 Tapered Piston Ring Compressor - 84.0mm (3.307")

$68.23

$68.23

The ARP 901-8400 tapered piston ring compressor is a precision-engineered tool designed to streamline the engine assembly process. Unlike generic adjustable compressors, this fixed-diameter tool ensures uniform compression of the piston rings for snag-free installation into the cylinder bore.

CNC-machined from premium 6061-T6 billet aluminum, this compressor features a hard-anodized finish for maximum wear resistance. The inner diameter is specifically tapered to guide the piston and rings smoothly into the block, significantly reducing the risk of ring breakage or damage to the cylinder wall during assembly.

  • Bore Diameter: 84.0mm (3.307")
  • Material: 6061-T6 Billet Aluminum
