Product Details

QA1 Precision Products carbon steel rod ends with left-hand threads are heim joints (also called rod end bearings or spherical rod ends). They are used in suspension linkages, control arms, panhard bars, steering linkages, and other articulating connections. A left-hand thread lets you pair the rod end with a right-hand threaded one on an adjustable link or turnbuckle-style assembly. This makes fine-tuning length and alignment easier.

Key Features:

  • Heat-treated bearing steel ball: 52100 bearing steel, precision ground and hard chrome plated for smooth, consistent articulation.
  • Carbon steel body: built for strength in demanding applications and protective coated for corrosion resistance.
  • Left-hand thread: for adjustable linkages that use opposing thread directions.
  • Precision construction: QA1 makes its rod ends to tight tolerances for dependable, low-play performance.
  • Range of configurations: the line includes options such as grease fittings, studs, and PTFE-lined versions, depending on the part number.

QA1 is a trusted name in performance suspension, and its rod ends are popular for street performance, racing, off-road, and industrial uses. Pick the child item that matches your bore, thread size, and configuration.
