Product Details

The QA1 KMR16 is a KM Series three-piece carbon steel male rod end featuring a 1-inch bore and right-hand threaded shank. Built using QA1's precision three-piece construction, the ball is pressed into a sleeve that is swaged around it to form an insert, which is then turned and staked into the rod end body. This process delivers superior ball-to-race conformity and tighter tolerances compared to standard two-piece designs, making the KMR16 well-suited for high-load applications where dimensional precision is critical.

I finally had time to install my part. The steering wheel hub was exactly what I needed at a great price and delivered promptly. Thanks for the great service.

I searched the internet high and low for the JKS Quicker Disconnects and almost thought it was a scam when I found them for this price! The order was simple and the shipping was fast. I could not be happier!

Great communication, super fast shipping, and product just as described. Very happy, thank you.

I found them doing a search for a clutch kit, they are hands down one of the easiest companys to work with and the prices cant be beat..... I looked everywhere

I would not hesitate buy from Autoplicity again!!! A+++

Autoplicity had the best price anywhere! I looked everywhere for the airaid intake system and they had it in stock. Great company!

good

Excellent price on kirkey seats! I will be buying from them again. Thanks for the prompt service
