Im putting a Challenger Lite on my girlfriends SRX, C-bolt cut me a cheap deal and even informd me of the trenching issue, but what could possibly be worse than the 121 thats on it lol. I figured i could play with the suspension as im using the skid from an 05 summit. I got my 01 mountain cat 144 to not trench so bad, maybe ill get lucky with this one! Next year regardless of how the track works, shes getting my powdermaxx, and im getting a camo extreme!
