Product Details

The QA1 JNL4A-6PK is a six-piece kit of lightweight aluminum jam nuts designed for left-hand threaded rod end and linkage applications. These nuts feature a 1/4-28 UNF left-hand thread and a 7/16" hex for easy installation with standard wrenches.

Key Features:

  • Material: Lightweight aluminum construction reduces overall assembly weight
  • Thread Specification: 1/4-28 UNF left-hand (LH) thread
  • Hex Size: 7/16" hex for standard wrench fitment
  • Quantity: Six (6) jam nuts included per kit
  • Application: Ideal for use with QA1 and compatible left-hand threaded rod ends, tie rods, and suspension linkage assemblies

QA1 aluminum jam nuts are a popular choice in racing and performance suspension builds where minimizing unsprung weight is a priority. The left-hand thread designation ensures correct pairing with LH-threaded rod ends, allowing for easy turnbuckle-style length adjustment on suspension and steering components.

Very quick easy transaction. Recommend to anyone looking for auto accessories.

great product at a great price

This is the first time I ordered from Autoplicity. Very good experience overall. The prices are the best I can find anywhere online. It was shipped very quickly, and I received my item just in time before my trip. Thanks!

Best price I found on a web..was in stock and received on time within the week..

I needed two fairly expensive parts for a project. Naturally, I shopped everywhere before deciding on where to purchase them. Autoplicity had the best price on the carburetor. I continued shopping around for the alternator, and ended up right back at the Autoplicity website, because they beat everyone else on that price also! And I don't mean by a few dollars! HUGE savings! Thanks Autoplicity! In the words of Arnold, "I'll be back!"

Adequate.

Very poor info on shipping. Order was sent in 2 separate shipments, but tracking notice indicated everything was sent in one shipment. When I received 1/2 of my order I called & was put on hold for over 20 minutes. The world's WORST music on hold.... Good prices though.
