1987-2004 Mustang, MM2 Race series rear shock for IRS, includes dust boot.

• Intended for track-driven Mustangs with rear coil-over spring rates of 600 lb/in to 650 lb/in.
• Exclusive MM valving designed for superb track performance, not for street ride quality.
• Includes an integral bumpstop
• Shocks do not include lower eyelet bushings because they are part of the coil-over conversion kit these shocks are intended to accompany.
• Not intended for use with conventional springs: Could produce a severe overdamped effect.

• Superb track performance, especially in wheel-to-wheel racing
• MM2 Race series shocks are made with patented mono-tube technology
• High nitrogen gas pressure prevents oil foaming and resultant fading
• Monotube design has better heat dissipation than twin-tube dampers, keeps the oil cooler, and decreases heat-induced damper fade
• Each MM2 Race series shock is tested on a shock dyno
• All MM shocks include dustcovers

Offered exclusively by Maximum Motorsports for open-tracking and wheel-to-wheel road racing. The MM2 Race series shocks are intended for track-driven IRS-equipped Mustangs with spring rates higher than the rates compatible with MM's Sport series dampers. Constructed with the highest-grade materials and extreme attention to detail, Maximum Motorsports manufactures the finest dampers possible.

MM2 Race series shocks are the perfect choice for a car that sees aggressive open-tracking, time trials, or wheel-to-wheel racing. Designed to control the coil-over spring rates required for on-track performance, the MM2 Race series shocks are intended for a track-driven cars equipped with coil-overs. The MM2 Race series rear shocks are ready to accept the MM rear coil-over conversion kit; they are manufactured with the groove in the shock body that is required by a coil-over conversion kit.

All MM non-adjustable shocks utilize patented mono-tube technology. Compared to twin-tube dampers, these provide better heat dissipation to keep the damper's oil cool, which decreases heat-induced damper fade. The highest nitrogen gas pressure available prevents oil foaming and fading. Every MM damper is tested on a shock dyno before leaving the factory to ensure quality.

All MM2 Race series IRS rear shocks come with an integral, progressive bump stop. All MM shocks include dustcovers.
