PERRIN Performance rear end links will increase the feedback and feel of your rear sway bar. Choosing the highest quality components, PERRIN end links are the essence of high-end suspension. PERRIN end links are precision cut from virgin aluminum ensuring strength, durability, and crisp sway bar response providing maximum performance and feel from your rear sway bar. PERRIN Performance end links feature PTFE Teflon lined spherical bearings. Teflon linings dampen against noise and vibration as well as keep dirt or road grime out of the bearing race. Perrin's spherical bearings are made from fiber reinforced, engineered plastic. With a static radial load resistance of over 5,000 lbs these bearings are virtually indestructible. Perrin's choice to use spherical bearings allows PERRIN end links to conform to dramatic angles while maintaining a solid link between the sway bar and control arm. Total misalignment angles will exceed 14 degrees. Perrin's research and development staff has developed a specific press technique for this bearing application that makes it impossible for the bearing to be removed once installed. The walls of the bearing-retaining surface are compressed onto the bearing in a double "swedge" technique. Do not be fooled by other products, which offer spherical bearing end links. The research and development time into this part far exceeds any other end link on the market.
