Product Details

The Akerly-Childs AC-RC4040 is a professional-grade piston ring compressor designed for installing pistons with a 4.040-inch bore diameter. This precision tool allows technicians to compress piston rings uniformly, enabling smooth piston insertion into the cylinder bore without damaging the rings or cylinder walls.

Key Features:

  • Sized for 4.040-inch bore diameter applications
  • Tapered design guides piston smoothly into cylinder
  • Durable construction for professional shop use
  • Essential tool for engine rebuilding and assembly
  • Prevents ring breakage during installation

Ring compressors are critical tools for any engine builder or mechanic performing piston installation. The AC-RC4040 ensures proper compression of all rings simultaneously, maintaining correct ring gap orientation while protecting both the rings and cylinder bore surface during assembly.

Awesome price and super fast shipping

Great price

Item and shipping as advertised.

Did not receive email with tracking number. When checking order online, the status indicated the order was in process. I was surprised when the order was delivered only three days after placement. I expected a longer wait time. Good price, fast delivery, 4.5 stars.

It was awesome

Ghhh

Simple and straightforward!

Great price and good company to buy from!

I ordered CV axles from Autoplicity and had them in less than a week! Definitely the best prices for quality product on this item. Will be a return customer for sure!

I was apprehensiveness at first to make a major purchase with Autoplicity due to their extremely low price and lack of reviews. I decided to take the chance and I am very glad I did. I made my order on a Monday morning at 0900 eastern time and my product arrived on Wednesday at 3pm. The item was exactly as described and the most astonishing part is that my purchase was released from the factory less than 45 days ago. I was expecting a model that had been sitting on a shelf for the last year and needed to be updated. That was not the case. I will definitely order from Autoplicity again in the future.

hard to find things but worth it

Very good price. Super quick delivery. Will def. buy from them again. Highley recomend them

Sweetest price on this K&N Filter anywhere! Shipped within 24hrs too. I'm coming back to shop for my car next.
