Product Details

The QA1 KFL16T is a K Series three-piece carbon steel female rod end featuring a self-lubricating PTFE liner, designed for high-load performance and racing applications. With a 1-inch bore and 1-1/4"-12 left-hand female thread, this rod end delivers precision fit and reliable articulation in demanding suspension and linkage environments.

Built using QA1's traditional three-piece construction, the ball is pressed into a sleeve that is swaged around it to form the insert. The insert O.D. is then turned down and faced off before being staked into the rod end body — a process that provides superior ball-to-race conformity and tighter tolerances compared to two-piece designs.

Key Features:

  • Ball: 52100 bearing steel — heat treated, precision ground, and hard chrome plated for exceptional wear resistance
  • Race/Body: Carbon steel (alloy/chromoly steel at manufacturer's option) with protective coating for corrosion resistance
  • Liner: PTFE (polytetrafluoroethylene) — self-lubricating for maintenance-free operation
  • Thread: 1-1/4"-12 left-hand female thread
  • Bore: 1.0000 in.
  • Design: Three-piece construction for tighter tolerances and better ball-to-race conformity
  • Grease fitting and stud configurations available separately

QA1's KF-T Series rod ends are a go-to choice for circle track racing, drag racing, street performance, and street rod builds where precision, strength, and low-maintenance articulation are essential.

Title

QA1 Suspension Rod End Bearing KFL16T

First time to order with Autoplicity (order #32934). The transaction is very smooth so far. The online ordering process is very clear and easy to follow. Fast shipping within two days after placing the order. Following-up email promptly notified the shipment.

Very competitive price, responsive customer service, very satisfied.

Great prices on a great product. Easy to navigate website! will be using them in the future for any additional parts I may need!

Ordered 4 race ramps flatstoppers for winter storage of my Dodge Viper. Product prevents flat spots on auto tires that are stored more than 30 days. Order process was extremely easy, product was promptly shipped. I'll definately do business with Autoplicity in the future.

Best price I could find. It was delivered just when I needed it. Thank you !

Wow that was fast. I ordered a Pertronix Ignitor conversion kit. Not only were they by far the lowest price I could find, they shipped within hours of submitting the order. I got the shipment in less than 24 hrs, even though I ordered ground shipping. I was a little bummed that they did not offer free shipping, as I am used to with other online places, but with their fast turnaround, I am not begrudging it. Sure it might have been because they have a warehouse nearby, but it was still unexpectedly impressive. The part arrived and looks like it all there and should be good to go. <br><br>I can't vouch for their customer service, but so far I am pleasantly surprised.

Fast -regular- shipping even on large items. I was skeptical at first but I am happy and don't regret my purchase!!!
