Product Details

The Prothane 6-111 is a complete polyurethane subframe bushing kit designed for the Independent Rear Suspension (IRS) subframe on 1979–1998 Ford Mustang Cobra models. Engineered to replace the soft, compliance-oriented OEM rubber bushings that deteriorate over time, this kit restores and improves chassis rigidity, rear-end alignment stability, and overall suspension response.

Prothane's proprietary polyurethane compound is significantly firmer than factory rubber, reducing subframe flex and deflection under hard acceleration, cornering, and braking. The result is more precise rear suspension geometry, improved tire contact, and sharper handling feedback — all without requiring permanent modifications to the vehicle.

Key Features:

  • High-durometer polyurethane construction for long-lasting performance and durability
  • Resists oil, grease, road grime, and ozone degradation
  • Reduces subframe movement for improved rear suspension accuracy
  • Direct OEM replacement — installs in factory bushing locations
  • Includes all necessary bushings for the IRS subframe
  • Supplied with Prothane's lifetime warranty grease for easy installation and long service life
  • Made in the USA

The Prothane 6-111 subframe bushing kit is an ideal upgrade for Mustang Cobra owners seeking improved handling performance, whether for street driving, road course use, or autocross competition. Installation is straightforward and follows standard bushing replacement procedures.

Decent shipping and definetly the lowest prices. Found a new grille for my truck 50 dollars lower than any other website.

Best price on Bilstein Shocks on the web. Ordered shocks on 4/25 and they shipped same day. FedEx has delivery date of 4/28. Received confirmation email after order was complete. Website had product inventory next to part number was very helpful. Other websites don't have this and this patprticular part is on back order for 30 + days. Will update once shipment received.

I searched for a quality automobile battery charger and found the best priced and longest warranty "smart" charger at Autoplicity and one other seller. Autoplicity carried a wider selection of the models offered by the manufacturer.<br> Looking over the website I entered my vehicles into the fields and found quality offerings. It is worth looking at.<br> Ordering was straight forward, shipping began the next day with a tracking number, and the order arrived on time. I bookmarked the website.

Great customer service. Prompt shipment and excellent prices. I will defiantly be ordering from them again. Just wish I would have found them sooner!!

Great price, fast shipping and the items was correct. A perfect transaction. Thank you!

I received my ARP head studs as described and on time with zero problems, and cheaper than anywhere else.Will use again!!!
