I love my Calmini rear skid/truss, however, just a warning. It gets snagged on rocks.
Yeah, I'm just a rookie driver and it was my first trip in the Tracker with the suspension, so I wasn't familiar with it...but still, it did get stuck a few times where I have to loosen the u-bolts and re-install the skid.
It started to pivot on the u-bolts that hold it, and it swing downward and got even closer to the ground, and started pushing against my brake lines on the rear side of the axle. To keep the front of it tucked away, I did this mod...I'd recommend it. Basic u-bolt, or I bent some all-thread. Yes, the two nuts hang down, but I think they are less of a hazard than without it.
Surprised they didn't do it from the factory...
And, it looks cool. I get a lot of people driving that compliment me on the truck or ask me "what the hell is that thing???" and a lot of people ask me also "what kinda rear axle you got under that thing???"
