  1. Maximum Motorsports IRS Subframe Bushings - MMIRSU-1
    $89.97

    Maximum Motorsports IRS Subframe Bushings

    Maximum Motorsports introduces a new product for IRS-equipped Mustangs: A Polyurethane IRS Subframe Bushing Kit. The polyurethane bushings in this kit are considerably less compliant than the stock rubber IRS subframe bushings. These stiffer bushings virtually eliminate displacement of the IRS subframe relative to the chassis. This reduces wheel hop during acceleration, braking and cornering. You'll feel a big improvement in your car's stability and predictability. Drivers have reported that the improvement is dramatic, similar to installing a Panhard Bar on a solid axle car. The polyurethane still provides very good noise isolation.

    NOTE: It has been found that Ford had put the incorrect bolt in the front mounting holes for retaining the IRS subframe on some 2003 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 the bolt size installed through the front IRS subframe mounts before ordering. If in doubt, or if you determine you need the larger bolts and corresponding nuts, the OEM replacements are available below. You will need two of each to do both sides.Learn More
  2. Maximum Motorsports Low Profile IRS Subframe Bolts (2) - MMF-1
    $14.95

    Maximum Motorsports 99-04 Cobra Low Profile IRS Subframe Bolts (2)

    With some of the larger tire and wheel combinations, the tire's sidewall can contact the head of the rearward IRS subframe-mounting bolt. Increased clearance for larger tires can be had with these low-profile bolts. At .350" tall, this low-profile bolt head and washer is 30% shorter than the .500" height of the factory bolt head. Even if there is some slight contact with the tire's sidewall, the nicely rounded head of this bolt will not damage the sidewall as readily as the sharp-cornered factory bolt head.Learn More
  3. Maximum Motorsports 99-04 IRS Subframe Bushing Removal Tool - MMT-6
    $24.97

    Maximum Motorsports 99-04 Cobra IRS Subframe Bushing Removal Tool

    MM developed this tool to help with the removal of the stock rubber bushings from the IRS subframe. Not only does this tool make the job much easier, it also reduces the time spent removing the stock bushings by at least an hour.Learn More
  4. Maximum Motorsports 99-04 Poly Front Control Arm Bushings - 4-3144
    $97.97

    Maximum Motorsports 99-04 Polyurethane Front Control Arm Bushings w/Shells

    Urethane front control arm bushings are full floating and nonbinding. In the front they maintain proper camber and caster alignment and give quicker turn-in response. These are a great upgrade for tired, soft, and worn out original rubber bushings that may never have been replaced! These bushings are installed after removing the factory bushings and shells. These are more complicated to install and position correctly, and are recommended if you have damaged shells, or accidentally removed the shells before installing bushings that require leaving the shells in place. The new bushings will have to be installed to the correct depth to prevent changes in caster, and smooth installation.Learn More
  5. Maximum Motorsports IRS Urethane Rear Differential Bushing - MMIRSB-46
    $52.94

    Maximum Motorsports IRS Urethane Rear Differential Bushing (Rear urethane bushing with removal tool)

    Rear Differential Bushing: MMIRSB-46

  6. For those who have replaced their front differential bushings with urethane, but still have the stock rubber rear bushing, we offer the rear bushing by itself.
  7. Includes the tool to easily remove the stock rubber bushing from its mounting bracket.


  8. Reduce wheel hop by installing stiffer differential mounting bushings. MM offers two types of differential bushings, urethane and aluminum. The urethane bushings are much stiffer than the original rubber, yet are still compliant enough to dampen NVH (Noise, Vibration and Harshness). The aluminum bushings allow no deflection at all, and therefore do more to reduce wheel hop. The aluminum bushings are designed to provide adjustment of the pinion angle. Properly setting the pinion angle helps keep driveline vibrations to a minimum.

    Unlike many others who offer only the front differential bushings, Maximum Motorsports took the time and effort to actually analyze the IRS system. The MM Engineering Team realized that all of the differential bushings must be replaced as a 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 will be created in the stiffness of the bushing materials. The more rigid front bushings will deflect less, while the remaining rubber rear bushing will still deflect as much as ever. This in turn 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. Wheel hop will still be prevalent because the rubber rear bushing will deflect and allow the differential to flop around.Learn More
  • Maximum Motorsports IRS Urethane Differential Bushings - MMIRSB-45
    $92.91

    Prevent damage caused by wheel hopwith Maximum Motorsports differential bushings.

    • Urethane bushings prevent rear cover breakage caused by wheel hop.
    • Urethane retains low NVH levels acceptable for daily-driven Cobras.
    • Includes all 3 bushing sets: The 2 front sets and the critical rear bushing.
    • Includes MM-designed tool to easily remove the rear bushing.
    • Retains stock differential location and pinion angle.
    • Adjusting pinion angle may reduce driveline vibrations. MM aluminum mounts allow adjustment of pinion angle.

    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 urethane or aluminum, prevent the violent flopping around that breaks differential covers.
