What's in the Box

  • (1) Polyurethane Upper Axle Bushing

Made in the USA

Product Description

Add some stiffness to the rear suspension of your 05-14 Mustang with urethane upper control arm bushings to reduce flex and increase grip. This is the Upper axle bushing located in the center of the top of the axle housing & is the mounting point for the upper control arm on 2005-2014 Mustang. This bushing will help decrease wheel hop and stabilize your rear end.

Bushing Lubrication
The suspension bushings included with this part can only be lubricated with PTFE grease, also referred to as "Marine Grease". PTFE grease is a very sticky, opaque grease that is water proof and will not degrade the bushing material. If lubed properly at installation, these bushings will not need to be lubricated again. Use of any other grease on these bushings will cause the bushing to fail and any bushing warranty to be voided.

Make sure you read the instructions and rent a ballpoint press. Not an easy install but I could tell a big difference. Stock axel bushing was junk.

This Item is the best once installed on your new Pony or old. Highly recommended. It only took me almost all Day. The only advise I would give is to rent or buy a Ball joint kit. I got mine at the local Auto store & magic!

Bought this bushing to replace the factory crappy bushing and it made a good bit of difference in the rear end feel. Installation is a little involved but not to bad. Used a drill bit to drill all around the old bushing and then used a wire wheel on a drill to clean out all the debree. Then it fits perfect and comes with plenty of greese.

Yes, I would recommend this item to a friend!

About This Brand

Lifted or lowered suspensions, increases in horsepower, plus-size wheels and tires can subject traditional rubber suspension bushings to forces beyond their limits. Control arms, strut arms, leaf springs, body mounts, motor mounts, transmission mounts, sway bars and shocks all control movement and maintain alignment but the rubber bushings they use are designed for more "middle of the road" use. Rubber also deteriorates over time, further reducing control. This contributes to premature component failure, a "spongy" ride and less than ideal performance handling. Urethane bushings can correct these conditions, and improve drivability in your Mustang or Ford Lightning.
