Product Details

The QA1 KFR4T is a K-Series three-piece carbon steel female rod end featuring a PTFE-lined alloy steel race for reduced friction and improved wear resistance. Designed for precision suspension, steering, and linkage applications, this rod end delivers reliable articulation with a self-lubricating race that minimizes maintenance requirements.

The KFR4T features a 1/4 in. bore and 1/4-28 right-hand female threads, making it a compact and versatile solution for tight-clearance linkage and suspension setups. The carbon steel body is protectively coated for corrosion resistance, while the precision-ground, hard chrome plated 52100 bearing steel ball ensures smooth operation and long service life.

Key Features:

Three-piece construction with female mounting configuration
Carbon steel body with protective corrosion-resistant coating
PTFE-lined alloy steel race for reduced friction and wear
52100 bearing steel ball — heat treated, hard chrome plated, and precision ground
1/4 in. bore diameter
1/4-28 right-hand thread pitch
Available in inch dimensions for easy integration with standard hardware

QA1's KF-T Carbon Steel Series rod ends are ideal for performance street, racing, and custom fabrication applications where a maintenance-friendly, low-friction female rod end is required.

Wow!! I came across Autoplicity while searching for a fuel pump for my Trans-Am. Not only did they have the cheapest price for the part, but they also had extremely reasonable shipping cost. Most websites claim to have free shipping but it seemed the cost of shipping was added to the cost of their part. Then I find out my order was processed and shipped within one business day!! I'll definately be bookmarking Autoplicity's home page!! Thanks!!

The item arrived fast and in good condition. There however seems to be a glitch with the scale the first time we weighed something. After we shut it off and then back on it seemed to be OK.
