Ring Compressors in 120 Sizes
ARP's ring compressors are CNC machined from 6061-T6 billet tube material and feature a true radius for each different bore diameter. What's more, they incorporate a wire O-ring relief. Type 3 anodizing is used for long life, and the bore size is prominently engraved in 3/4˝ high numbers for easy identification. Standard stocking sizes from 3.552˝ to 4.750˝ (SAE) and 75mm to 95.5mm (metric). The true radius design is far superior to conventional “tapered” devices, and widely acclaimed by professional engine builders! This is truly the very best piston ring compressor on the market today.

ARP Ultra-Torque™
Fastener Assembly Lubricant
Today's critical diesel fasteners - head studs and bolts, main studs and bolts, and driveline - have been designed stronger than ever before to handle the extreme loads. As a results, installation pre-loads - the amount the fastener is stretched during installation - are very high.
There are a lot of opinions out there about which fastener assembly lube to use and what the torque value should be. First, let's be clear: ARP provides torque specs for our fasteners based on using ARP Ultra-Torque. If you're not using our specs and our lube, you have no real idea what pre-load you're getting. We've done the testing where we can measure the torque applied and the resulting pre-loads. We've tested with our lube and the others people use...and we've got the results to back it up. (It's not like we're trying to sell more lube - we send you some free in every kit! We just want you're installation to be right.)
The slides below will show why you should use ARP Ultra-Torque:
