The Original Pro-Action rear suspension was used in the SRV, Vmax540, Exciter II, and the Vmax4 and last used in the 94-96 Vmax 5-600 sleds. The SRV/Vmax540 listed the travel as 5.9" and the 94-96 Vmax 5-600 sleds as 8.5" ? I purchased the front and rear arms plus the rear shock off a 1994 Vmax 500 and the only difference is the newer arms are tubular verse channel for my old Vmax. The rear of rear shock is the same center to center lenght and all shock mounts are in the same position ! Everything matches up the same although I did not get the limiter straps from the newer 500 so, what is the deal ? I'm bummed where is the extra 2.5 inches ?
