For any of you guys that are thinking about converting your sled to a 144" track, I thought that I would pass along some information that I recently got directly from someone at Camoplast.
If you are looking for a Cobra style track with the 1.35" lug height in a 144" length, they will be coming out with a 144" version in the standard 2.52" pitch. This track will be fully clipped, all open windows, and will be the standard 2-ply track that is found on most sleds. Estimated weight is 44 lbs. Part #9107H.
They are also coming out with a Cobra track in a 146" length that is going to be using the new single ply for weight savings. This track will be using a 2.86" pitch, so you would need to change the drive sprockets. This track will be fully clipped, all open windows, and the estimated weight is 40 lbs. Part # 9094H.
They expect these tracks to be available in August. It's nice to have another option available in the 144" length for a crossover type sled.
I'm going to be extending my 136" SRX even longer, and am going to give the new 146" track a try.
