Product Details

The QA1 KFR16 is a KF Series 3-piece carbon steel female rod end featuring a 1-inch bore and a 1-1/4 inch-12 right-hand thread. Built using QA1's precision three-piece construction, the ball is pressed into a sleeve that is swaged around it to form an insert. The insert's outer diameter is then turned down and faced off to ensure square sides before staking into the rod end body. This process delivers superior ball-to-race conformity and tighter tolerances, making the KFR16 an excellent choice for high-load, precision-critical applications in racing, suspension, and performance drivetrain systems.

QA1 Suspension Rod End Bearing KFR16

Autoplicity had the best price by far on the item I was looking for. I paid for 2nd day air shipping and my order total was still less expensive than ordering from any other merchant. My item arrived the day after I ordered it. I will definitely buy from them in the future.

Best price fast shipping. will deffinitly order again

Best Price on the Net for K&N System for my 2012 HEMI RAM. My Order 18270 is shipping today and I can't wait to get it installed!

We ordered a Impact racing helmet for $100.00 less than what we would've paid the manufacturer. We received it sooner than expected. The helmet was excellent!! We would order for this site again in the future!!! Thank you Autoplicity!!

Best price on the Internet and quick shipping

Very fast and easy ordering system. My order was shipped the next day.

excellent pricing!

So far so good! Just ordered the parts I needed for my car which I've been trying to find EVERYWHERE without success, until I arrived at autoplicity. Great price, and with a lifetime warranty I'm assuming great quality. I have faith that when the product arrives I will be highly satisfied.
