Product Details

The QA1 KML4-5Z is a 3-piece chrome-moly steel male rod end engineered for high-performance steering, suspension, and linkage applications. Featuring a left-hand threaded shank, this rod end allows for easy adjustment of tie rod or push-pull rod length without full disassembly, making it a preferred choice in racing and performance builds.

QA1's 3-piece rod end design incorporates a hardened chrome-moly steel housing, a precision-ground ball stud, and a high-strength race insert, delivering superior strength and durability over standard OEM-style ends. The included Zerk grease fitting enables routine lubrication to extend service life and maintain smooth articulation under load.

Key Features:

  • 3-piece chrome-moly steel construction for maximum strength and durability
  • Male shank with left-hand (LH) thread for use in adjustable rod assemblies
  • 1/4" (0.250") bore diameter for the pivot/ball end
  • 5/16"-24 threaded shank for easy installation and adjustment
  • Zerk grease fitting included for field lubrication and extended service life
  • Precision-ground ball for smooth, low-friction articulation
  • Ideal for steering tie rods, panhard bars, sway bar end links, and custom fabrication

QA1 rod ends are manufactured to strict tolerances and are a trusted choice among professional race teams and performance enthusiasts. The KML4-5Z is sold individually and is compatible with standard 5/16"-24 threaded rod ends in left-hand thread configurations.

On Monday I placed an order for a Moroso Battery Switch (which was competitively priced BTW) and sitting here Wed afternoon I've got my switch in hand. Autoplicity was perfect every step of the way, including immediate notification of the order receipt, notification of shipment, even notification that it had been delivered (and it was waiting on my front porch). Packing was suitable too. Couldn't be happier. Buy with confidence. Kev

I ordered a Derale 14204 Trans oil pan from Autoplicity -<br>it arrived quickly, in good shape (was well packed for shipment)<br>More than pleased.... (best price was a bonus)<br>-HBP-

Autoplicity had the lowest listing price for a part which I had done extensive research. To make the deal much sweeter, free shipping! On top of that, part was delivered in only a few days! Really, there was no reason NOT to order from them. Great prices and fast response are the reasons why I look forward to continued business with Autoplicity. Overall a positive experience, so I highly recommend.

Excellent prices, inventory and fast service. I placed my order on Saturday, Aug 4, it was shipped on Monday, Aug 6, and due to arrive on Friday. I will be a repeat customer with prices and service like this.

Very good price on k&n air filter, will definitely order from autoplicity again.

In a rush to get my car up and running, Autoplicity had the best price on the items I needed, and in stock as well as shipped quickly. Just what I was looking for, thanks!

I did a price comparison for hard-to-find Redline motor and tranmission oil of over 30 different vendors and websites through Amazon, E-bay, Google, etc. and Autoplicity had the best price by 25-30%. It was a no-brainer to order from them, and their website is easy search and manage. And their shipping charges aren't too bad either.

Super quick service! Great price and I received the product the day after I ordered it.
