AFCO M2 Double Adjustable Mono-Tube shocks truly are the ultimate track weapons! No other shock on the market today can match the M2's innovative list of features. The M2's ability to keep the tires in compliance with any track surface condition from tack to slick, bumpy to smooth, rutted to washboard, lies in its combination of low friction and quick reacting components.
At the heart of the M2 is the unique bladder design. While other floating piston designs effectively "turn off" while trying to overcome stiction and changes in direction, the M2's gas inflated bladder is able to expand and compress at incomparably high speeds, very slow speeds, very small movements, and large deflection all at the same time with virtually no resistance or friction. The result is a feeling of being stuck to the track rather than riding over it.
Due to its unique design, the adjustments you make with the M2 have a very large effect on handling.
The M2's mono-tube, gas pressure design coupled with its superior valve design and use of gas charged bladder provide real, substantial control of compression and rebound resistances throughout the entire velocity range. This means the M2's adjustments are much more pronounced and provide more sensitive and extended low speed adjustments for increased effective tuning range.
For dirt late models. Includes tuning instructions, coilover kit and dyno sheet.
