Product Details

QA1 Precision Products left-hand thread spherical rod ends (also called heim joints or rod end bearings) are made for suspension linkages, control arms, trailing arms, 4-link setups, ladder bars, and other custom chassis and racing uses. The left-hand thread works with a matching right-hand rod end on the opposite end of a link or tie rod. Turning the link adjusts its length without removing either end.

Key Features:

  • Spherical rod end design: The ball swivels inside the housing, so the joint accommodates misalignment and angular movement in suspension and steering links.
  • Left-hand thread: Used with right-hand rod ends for adjustable links, which makes alignment and geometry changes easier.
  • Heat-treated steel components: The balls are precision ground, and the housings and races are heat treated for strength and durability.
  • Protective finishes: Corrosion-resistant platings and coatings help the parts hold up in demanding environments.
  • Multiple constructions: The line includes male and female threaded styles. Depending on the series, races are either non-lubricated steel or self-lubricating PTFE-lined.
  • Industry standard design: QA1 builds its rod ends to meet SAE J1120 standards.

QA1 has a long record of making precision suspension components for street performance, drag racing, circle track, and off-road builds. Choose the child item that matches your required bore, thread size, and style.
