Drop brackets are the SHIZ! Two winters ago I struggled to get my sled to sidehill, to keep the ski's down when climbing steep hills, and to keep the boards from dragging in the deep stuff, even after extensive suspension adjustments. So, last summer I removed the front sway bar, swapped the left and right skis, and fabricated my own 3 1/2" billet aluminum drop brackets. WOW!!! It was like riding a completely different machine last year. It is almost effortless handling it on sidehills, the skis stick to the hills longer on climbs, and the boards are obviously much higher out of the snow, because, MAN it digs some trenches! It raised the rear bumper 7" from the stock position. I don't know what those guys are talking about when they say the track binds, and that you have to lower the front axles. I rode it all last season, and did not experience any binding, and did not lower my axles.
I would definately recommend this mod! It is the best mod I've done to my sled yet, and cost me no more than a little time and effort. If you don't have the ability to fabricate your own, you may want to try a kit.
Hope this helps
