Prothane Universal Endlinks

universal endlinks

Endlinks may be overlooked a lot of times, but they are an intricate part in the suspension. 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. Replace those old rubber grommets with Prothane's polyurethane endlink bushings, 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 table below to find the correct endlinks for your vehicle.

Adjustable Threaded Endlinks

The endlinks in this table are not made by Prothane. They are made by the manufacturer Whiteline. Whiteline's adjustable threaded endlinks are built differently from Prothane's endlinks. Whiteline Universal Endlinks for-go the use of a spacer sleeve and instead utilize a double threaded bolt that allows for a secondary nut to be threaded up or down either side of the endlink in order to fit a wider range of spacings between the sway bar and its mounting point.
