Featuring a male, right-hand threaded 1/4-28 stud and a 1/4" bore, this rod end delivers precise articulation and superior strength over standard stamped or 2-piece designs.

Key Features:

  • H-Series 3-piece alloy construction for high tensile strength and durability under load
  • Male right-hand thread ? 1/4-28 UNF stud thread
  • 1/4" bore for compatible attachment hardware
  • High misalignment tolerance allows for angular movement to accommodate suspension travel and steering geometry changes
  • Precision chromoly inner race with PTFE-lined ball for smooth, low-friction articulation
  • Corrosion-resistant alloy housing suitable for racing and performance street use
  • Designed and manufactured by QA1 Precision Products, a trusted name in American-made performance suspension components

The QA1 HMR4S rod end is ideal for use in custom steering linkages, panhard bars, push/pull rods, and other high-cycle performance applications where precision and reliability are critical. It is sold as a single rod end.

I looked around for few months on where to go to purchase JBA headers for my 01 Tundra. I came across Autoplicity and their prices were untouchable. I even called to speak with a sales representative and he gave me a discount code for my purchase. I would highly recommend doing business and plan on doing more business with them.

Great prices

Great site. Easy to locate items and they have the best prices! I will be using this site for all my custom parts.

Best price I could find on line, shipped really fast. With how low the price is I was worried but everything came fast and it was the correct parts. This place really keeps the cost of racing down.

I received my ARP head studs as described and on time with zero problems, and cheaper than anywhere else.Will use again!!!

Best price I could find anywhere. Almost 10% less than my typical sources and the item shipped in less than 24 hrs.<br>
