Product Details

The Prothane 7-1158-BL is a rear stabilizer bar bushing kit designed to replace the factory rubber bushings on your vehicle's 19mm sway bar. OEM rubber bushings deteriorate over time, becoming soft and compliant, which allows excessive body roll and reduces handling precision. Prothane's polyurethane construction restores and improves upon the original performance of your anti-roll bar system.

Key Features:

  • Material: Firm polyurethane construction — significantly stiffer than stock rubber for improved handling response
  • Grooved Bore Design: Internal grooves are engineered to retain Prothane's included super grease, ensuring quiet, squeak-free operation over the long term
  • 19mm Bore Diameter: Precision-fit for factory 19mm rear stabilizer bars
  • Black Color: Classic black polyurethane finish (BL designation)
  • Durability: Polyurethane resists oil, ozone, and road chemicals far better than OEM rubber, providing a longer service life
  • Direct Replacement: Bolt-on fitment with no modifications required

This kit includes the bushings and Prothane super grease necessary for proper installation. By upgrading to Prothane polyurethane bushings, drivers can expect reduced body roll, sharper turn-in response, and more consistent handling characteristics. Compatible with factory sway bar diameters as well as larger-diameter aftermarket performance sway bars of the same 19mm size.

FIRST TIME BUYER - WE'LL SEE HOW IT ALL GOES

Ordered a couple of items. The first was a air intake kit. I had put in all my info for my truck and chose one from the list to order. Won't fit. Called to tell them and they asked if I had called manufacturer...ummm no. Said I needed to contact them to verify wrong part. They were closed, so went to website. The part they sent me was a universal fit- for cars, not trucks, but did find right model- $90 more. Called back autoplicity and was told I need to go through email to get an RA# to return wrong part- site says I can call. Been on hold for over 20 mins and still waiting. Hope the Nerf bars I ordered fit! Update- they called me back, got my RA#. Very pleased with how Nick handled things- it was what I expected the first time. He verified the NERF bars will fit and will be changing the website so the universal intake does not show on list for vehicles with larger air outlets. Changing my rating to show my satisfaction with how it was eventually handled.

Lowest prices of what I was looking for and super fast shipping!!

Great company best prices around and would highly recommend

Part and price I was looking for.

"Customer service was very helpful, very good prices. On its way the next day."
