Reviews

High quality bearing used to replace broken (less robust) bearing on my RV Rocket Steering Link which led to a 270 deg ground loop (fortunately with only minor damage to wheel pant). I highly recommend replacing original bearings with this one.

Heim rod ends are always worth the extra money. Good insurance and they last forever.

The Heim rod end bearings that I ordered were a perfect fit, the detailed description in the catalog made it easy to select the correct bearing. The new bearings took the slop out of my control rods.

Bought this to replace the rod end bearings on my RV-Rocket steering link, one of which had broken. High quality construction much more robust than original. Removed one star as item was back ordered almost a month...
