Product Details

The Prothane 6-1143-BL is a black polyurethane rear sway bar bushing kit designed to replace worn or soft factory rubber bushings on the rear stabilizer bar. Upgrading to Prothane's firm polyurethane construction significantly improves the sway bar's ability to control body roll, increase traction, and sharpen handling response — performance that worn rubber simply cannot deliver.

Prothane's polyurethane material resists flex and deformation far better than stock rubber, keeping the sway bar firmly located under hard cornering or off-road stress. Each bushing features a grooved bore engineered to retain Prothane's included super grease, ensuring smooth, quiet operation over the life of the bushing.

Key Features:

  • 22mm bore diameter — matches OEM rear stabilizer bar diameter
  • Black polyurethane construction — firmer and more durable than stock rubber
  • Grooved bore design — retains lubrication for quiet, rattle-free operation
  • Direct OEM replacement fit — bolt-in installation with no modification required
  • 4WD-specific application — engineered for rear sway bar duty on four-wheel drive platforms
  • Backed by Prothane's lifetime warranty

This kit is a straightforward upgrade for any driver looking to restore or improve rear suspension stability. The black color blends cleanly with factory underbody components, making it a practical choice for both performance builds and daily drivers.

So I left a review already about autoplicity and it was before I even checked when it was going to be delivered. I was happy to see it was already shipped but even more excited and pleased to see that it was only going to take two days to get here! Scheduled for delivery tomorrow! Could not be any happier with this company!

Great service! A+++++++++

Quick shipping and a part that worked.<br><br>order 104-9436863-0564219

This was my first order with Autoplicity. I was pleasantly surprised when my order showed up quickly and was exactly what I wanted. I will be buying from this company again. Thanks for the quick service and fair pricing.

Autoplicity had a MSD Timing Twister that was discontinued and no one had in stock. I called 6 places before getting in touch with them. Ordered part and had it in a matter of days.

The items shipped and arrived really fast. This was a great transaction even though shipping was a little high.

pleased so far
