McDonald Connors Racing is your source for dirt bike, ATV, sled, and dirt track car suspension repairs, revalving, and modifications for competition and recreational users. MCR can set up your suspension for supercross, motocross, snowcross and woods racing like no other suspension shop in the area! We have the valving mods and performance products you need to become a faster, safer rider. MCR can give you the best overall MX suspension performance upgrade per dollar compared to any other piston revalve mod available in the world!

MCR is also an authorized AFCO Racing dealer. Why buy new AFCO shocks when we can repair your damaged ones for a fraction of the cost?

How can MCR give you the best performance set-up available? MCR is an authorized Ride Concepts Inc dealer. Ride Concepts develops the most advanced motocross fork and shock pistons available. Their front and rear motocross suspension mods help lower the lap times of riders at the highest levels of competition.

The T6-series fork pistons are the only digressive triple port high velocity motocross piston in the world! This is a fully tunable fork piston specifically designed to dramatically improve the passive valving in your forks which creates cornering and braking traction like no other fork piston physically can. This directly improves the ongoing compromise that plagues your stock forks regardless of how they are set-up using the stock piston.

The T6-series shock pistons are the ONLY speed sensitive shock pistons in the world. They are also the ONLY motocross shock pistons that offer a performance enhancement over the existing stock components! This linear digression dual velocity ported piston optimizes shim tip surface area and varies initial flow rates to the valving shims which equates to the most acceleration and braking traction possible along with rider feedback without a hint of harshness.

“This level of performance is simply and physically unobtainable using the stock, or any current aftermarket piston in the industry, regardless of the valving!”
