Terra Alps Racing Yamaha Stock Nytro tunnel kit

Have a MCX rear mount turbo or front mount turbo, these are the best tunnels made.

Our tunnels have all the holes in the chassis and come with hardware for easy installation. Also have the holes for stock suspensions with adjustablility not found in the stock tunnel or others. Holes in place for EZ Ryde and M10 suspensions. We redesigned the tunnels dimensions to easily accept 16" wide tracks, other builders do not offer this. With all our Yamaha tunnels we include new inner and outer reinforcement brackets to strengthen the chassis for years of riding, not months. The tunnel kit comes with all our standard design components such as our Terra Alps designed open slot foot traction on the running boards, now being copied by others, running board stiffeners for aggressive jumpers, L E D tail light for safety and function, and craftmanship we put into all our chassis kits. Remember these are not just a replacement tunnel, these tunnels are better then stock and designed to be the best.
