Product Details

The ARP 900-0100 piston ring compressor is a precision-engineered tool designed for professional engine builders and serious enthusiasts. CNC-machined from 6061-T6 billet aluminum tube material, this ring compressor features a true radius design that is far superior to conventional tapered compressors, ensuring safe and accurate piston installation without damaging rings.

Key Features:

  • CNC-machined from 6061-T6 billet aluminum for strength and durability
  • True radius design matches bore diameter precisely for optimal ring compression
  • Relieved bottom edge accommodates wire O-rings on pistons
  • Type 3 hard anodized finish for extended tool life and corrosion resistance
  • Bore size prominently engraved in 3/4-inch high numbers for easy identification
  • Professional-grade construction trusted by engine builders

Unlike tapered ring compressors that can twist or damage piston rings during installation, the true radius design of this ARP compressor provides uniform compression around the entire ring pack. The hard anodized finish ensures smooth operation and long service life, while the engraved bore size marking allows for quick identification in your toolbox. Available in sizes ranging from 3.552 to 4.750 inches (SAE) and 75mm to 95.5mm (metric).

My order #4383 was fulfilled quickly and shipped in a timely fashion. The price was super competative and the web site is user friendly. I will be back for more I'm sure! Shipping should be free for orders over a certain price, say $50?!?!

So I left a review already about autoplicity and it was before I even checked when it was going to be delivered. I was happy to see it was already shipped but even more excited and pleased to see that it was only going to take two days to get here! Scheduled for delivery tomorrow! Could not be any happier with this company!
