rear winch for axle?

[tlc81]

This might not be the right place for this question but Im not sure if its a recovery device or a hardcore suspension mod??

I see many trucks running a smaller rear winch with the cable mounted to the diff of the rear axle. Most of these rigs appear to be running coils and shocks with some kind of 3 link set up.

Is this strictly for limiting the travel of the rear suspension or is it so the driver can lower the rear end of the truck???

Sorry that I have to ask such a question< I know there will be a very logical explanation

Hi All:

I have a buddy with a SOA VJ40 with lots of rear wheel travel.

He has a 2K ATV winch mounted to the rear frame above the axle, specifically to restrict the rear suspension travel at certain (off-road) obstacles.

Completely different idea than a rear-mounted recovery winch.

Regards,

Alan

When you have a flexy suspension it will sometimes "unload" if the weight distribution changes. Imagine dropping off of a ledge, as more weight transfers to the front axle the rear end gets lighter, if the cog gets far enough away from the rear axle the springs will resume their natural length, or shape in the case of leafs, this is referred to as unloading. You can drive out of this situation by accelerating fast enough to get the front axle ahead of the rear axle, but it takes big cajones. The same thing can happen with the front axle when climbing a steep ledge. I have no idea how you would recover from that one.

The axle winch doesn't allow the suspension to extend beyond it's static, loaded position. This doesn't affect articulation because the center of the axle remains pretty close to the same distance from the frame no matter how much you rotate the ends.
