Included in this kit are: 4 oversize UHMW subframe bushings, 4 aluminum sleeves.

Use this kit when you accidentally remove the outer metal sleeve when removing the OEM subframe bushings.

Stabilize the subframe by removing the OEM rubber bushings and replacing them with this kit.

By stabilizing the subframe with this kit, handling will be more predictable and will also prevent wheel hop.

Prevent damage caused by wheel hop by installing Maximum Motorsports differential bushings.

Aluminum mounts prevent rear cover breakage caused by wheel hop.
Adjustable to set pinion angle, possible change of over 4 degrees.
Includes aluminum mounts for all 3 bushing sets: The 2 front sets and the critical rear bushing.
Adjusting pinion angle may reduce driveline vibrations.
Recommended for the hard launches of drag racing.
Recommended for high-powered Cobras.
Compatible with the Fore brand differential cover.
Expect an increase in noise heard from the rear gears. Use MM urethane bushings if increased noise is a concern.
Wheel Hop Breaks Parts

Wheel hop can break the rear differential cover.
Wheel hop causes violent movement of the differential.
Violent flopping around of the differential can break the differential cover, where it attaches to the rear mount.
Violent movement is allowed by the overly compliant stock rubber differential mounting bushings.
Stiffer bushings, whether aluminum or urethane, prevent the violent flopping around that breaks differential covers.
The front differential bushings are specially machined spherical washer sets. This unique MM design allows compensation for the changed angle of the differential housing. Aluminum bushings without this feature increase stress on the attachment bolts, the differential mounting ears, and the IRS subframe.

Unlike many others who offer only the front differential bushings, Maximum Motorsports took the time and effort to analyze the IRS system. The MM Engineering Team realized that all of the differential bushings must be replaced as a complete set.
The complete set includes the two front bushings and the essential single rear bushing.
If only the front bushings are replaced, and the original rubber rear bushing is left in place, a mismatch in the stiffness of the bushing materials will be created. The more rigid front bushings will deflect less, while the remaining rubber rear bushing will still deflect as much as ever.
Damage from wheel hop will still be possible because the rubber rear bushing will deflect and allow the differential to flop around.
The mismatch in bushing stiffness will increase the stress on the aluminum front mounting ears of the differential housing. The increased stress can lead to fatigue and stress cracking of the aluminum differential housing.Learn More

Replacing the stock rubber swaybar bushings with firmer urethane will improve your IRS-equipped car's handling by precisely locating the rear swaybar. Fits All stock Mustang Cobra IRS swaybars, 1999-2004 Details Rubber bushings may allow the swaybar to move up and down relative to the chassis because, rather than just allowing the swaybar to pivot, the rubber can also compress. When the swaybar compresses the pivot bushings instead of purely rotating, the swaybar does not provide the same roll resistance at all times, and the car's handling will not be consistent or predictable. Rubber bushings can suffer significant deterioration after only a few short years. Urethane bushings will restore an older car's handling to better than new. These 26mm bushings fit the stock Ford IRS rear swaybar and its mounting brackets on the 1999-04 Cobra models. Note: These bushings were recently revised. They now properly fit all 1999-04 Cobra models.

Maximum Motorsports 99-04 Cobra IRS Subframe Front Mounting Nut

It has been found that Ford had put the incorrect bolt in the front mounting holes for retaining the IRS subframe on some 2003-4 Cobras. The sleeve in the bushing and hole in the chassis are designed for a 14mm diameter bolt, however many cars had 12mm bolts installed incorrectly from the factory. If you have been noticing noise from the rear suspension, it may be caused by the subframe shifting due to insufficent retention with the smaller bolts. Verify your bolt size installed through the front IRS subframe mounts before ordering. You will need two bolts and two nuts to do both sides.Learn More
