First select the link style you need based on your year make and model. Then add the desired measurement to the end of the part number. For example, if you need an 8-1/2 “ sway bar end link for your 2006 Dodge Ram 2500. The link style would be SMX-1226. The 8.5” version would be SMX-122685 or for an 8” version SMX-122680. We can build you a sway bar link for your RAM up to 12” Center to Center! Depending on your model Please verify the style of end link you need for your truck. Dodge has changed the sway bar links in some cases every two years and we have done our best to narrow the sway bar links down to the exact year make and model.
