Product Details

ARP 900-3900 Piston Ring Compressors

Ring Compressor

ARPs new ring compressors are CNC machined from 6061-T6 billet tube material and feature a true radius for each different bore diameter. Whats more, they are relieved for wire O-rings on bottom. 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.

Good description

Good this far.

The Amazon for auto parts!!

Quick shipment of order.

very easy, and great price

found what I need on the first try and it was priced better than another place.

Super fast. I like the paypal and amazon pay option. repeat customer for sure.

Very easy

Quick and straight forward. Good Job!

So far it was pretty painless, let's see how quickly the parts arrive. A guesstimate of when to expect parts would've been nice. The only thing that wasn't amazing about the overall experience was that the tracking number provided did not work properly, and items did not say 'shipped' on your website until the day I received them on my end.

Bought an Autometer Ultra lite 2 pyrometer and it looks great. Autoplicity has the best prices on their products and ships their products very quickly. I will definetly buy from them again.
