Product Details

The ARP 901-7950 is a precision-engineered piston ring compressor designed for professional engine builders and serious enthusiasts. CNC-machined from 6061-T6 billet aluminum tube material, this tool delivers exceptional durability and accuracy for piston installation.

Key Features:

  • True radius design for precise bore diameter matching—far superior to conventional tapered compressors
  • CNC-machined from 6061-T6 billet aluminum for strength and longevity
  • Relieved bottom edge accommodates wire O-rings without interference
  • Type 3 hard anodized finish resists wear and corrosion
  • Bore size engraved in large 3/4-inch high numbers for quick identification
  • Available in sizes ranging from 3.552 to 4.750 inches (SAE) and 75mm to 95.5mm (metric)

This ring compressor's true radius design ensures even pressure distribution around the entire ring pack, preventing ring damage during installation and making piston insertion smooth and controlled. Professional engine builders prefer ARP ring compressors for their precision fit and reliability on high-performance builds.

this is my new home... very cool site, beat summit and jegs by $20 to $30

Extremely Happy! Best price on the web, easy order tracking, if only all online orders from other sources were this easy. I ordered a component from another online retailer who showed parts "in stock" only to see my status as "sent to warehouse" and it was weeks. When Autoplicity shows "in stock" it really was and delivered right away.

easy - nice to be able to pay via amazon. Quick delivery, all as promised. Product: Titan SideKick tank. Tank and ground seem well made. Shape allows mounting with minimal interference with bed layout. My PowerTrax bed cover moves freely above the SideK

It took exactly a week for the part to be shipped because the part came directly from the supplier. But the price was the lowest around.

Shipped very quickly and had the best price I could find!

I just received my order 7260 very quickly and it was as I had ordered............very easy to order and would do business with them again and I also will recommend them to others.

Better prices and even better service. Will do business with again.

Perfect item, fast shipment, great communication, and the best price.

Great communication, lowest price I could find anywhere, and quick shipping with a tracking number. What more could you ask for. 2nd time dealing with them and still impressed! order# 6935

They had exactly what I needed and the cheapest price i found anywhere.
