As most of you know I have a 1988 Tundra that I love dearly. However it's a bear on my back. The other day I was riding up in hatchers when I saw the identical sled with 2 major exceptions, first it had 1.5 inch paddles on the track and second it sat way up like a more modern sled. Is there a major readjustment I could do or do you think they retro fitted the sled with a new suspension system? Different shock maybe?
