Product Details

The QA1 Precision Products Wide Bearing line offers wide series spherical bearings, also called spherical rod end bearings or heim joint bearings. They are built for suspension linkages, control arms, trailing arms, and other chassis applications where smooth articulation and durability are needed.

Key Features:

  • Wide series spherical design that provides a larger bearing surface for greater load support
  • PTFE (Teflon) liner for smooth, low-friction movement and reduced maintenance
  • Precision-machined construction for consistent fit and dependable performance
  • Allows angular misalignment, so the joint can move through its range without binding
  • Available in multiple bore sizes and variants to suit different suspension and linkage setups

QA1 is known for precision suspension components used in street performance, racing, and custom builds. Each bearing in this line is designed for long service life under demanding conditions, which makes it a good choice for upgrading or rebuilding suspension linkages.

Overall good experience. Easy checkout online & fast delivery to my address. Box was a bit beat up with some good size holes on one side when it arrived, like it was sort of opened, but that's really on the shipper, no fault of THMotorsports.

Thanks for the fast response

Quick and efficient ordering with reasonable prices

yes

Easy to look up and order

Everything came in really quick and packed well. Apparently I just ordered the wrong part.
