Prothane Universal End Links

Prothane's Universal Sway Bar Endlinks attach the control arm to the sway bar with polyurethane endlink bushings, adding stability, handling and durability to your suspension. OE rubber endlink grommets crack and rot away, reducing your handling performance and stability. If the hardware is looking rough as well then you can replace the entire endlink with Prothane's complete kits that include everything down to the last washer. If the hardware looks fine and the grommets are all you need to replace Prothane offers individual kits of highly durable Polyurethane Grommets of various sizes, Made in the USA and backed with a Lifetime Warranty.

How-to Measure your Endlinks

If your vehicle uses standard straight bolt endlinks, you can use this page to find the correct Universal Endlinks. With the car level on the ground, check to make sure the sway bar bar and control arms are parallel to each other (B and C). Once they're parallel, you can measure the “A” dimension. (front center of stabilizer bar to control arm) and compare the measured length to the table below to find the correct endlinks for your vehicle.
