Winches that is. Why to these competition rock buggies have winches that seem to be used as limit straps for the suspension? Educate me 
Why do they do that? (1 Viewer)

Way to compress front suspension actively to keep the very flexy/bouncy/light front ends from swapping with the rearend.
Just what I've read and heard.

By using the winch to hold the stored energy in the front suspension, it prevents the front "kicking off" on steep inclines, when weight is taken off the front, and by compressing the suspension, it also changes the COG.
When the winch cable is hooked to the centre of the live axle, it allows the suspension to work still, on a side to side articulation basis, without being able to extend fully.

I don't cinch my front or rear axle down, but do run a rear limit strap and a front limit chain...keeps full articulation intact, but prevents BOTH tires from drooping together fully...the cinch option is just an extension of that....
If you've seen any pics from SuperCrawlIII, you'll see the extreme climbs these guys do, and allowing the front suspension to unload would flip them WAY earlier than most did...lol

In addition to preventing "unloading" of the front axle on really steep climbs, when you keep the front axle winched up, you get more weight and hence traction on the front tires. I do it on my rig and know that I can climb better with the front winched up.
never even heard of that, but sounds pretty cool

I think a few post kind of mentioned this, but a lot of the comp buggies run long-travel compressed Nitrogen shocks, and they tend to 'pogo' when unloaded. On flat ground, there's roughly half the weight of the vehicle sitting on the front suspension. When you start getting closer to vertical, the suspended weight decreases. When there's very little weight on the front end, those long travel shocks will extend fully, pushing you back even farther.
Kind of hard to explain without pictures, but you get the idea.
