Hey all,

My friends with full size pickup trucks are normally the ones to launch and trailer our boat, but they were out of town one weekend so I was tasked with it. I had some wheel slippage on the ramp when getting the boat out of the water, and I'd like to know if there was a better way of doing this.

I have a fully stock 2006 4R V8 sport edition. Tires are at 32 psi all around. The boat, equipment, and trailer together weight roughly 4000 lbs, give or take. Kind of a heavy load for my truck, and there is quite a bit of rear sag when I tow. The ramp was wet from other trailers dripping on it, so I put it in 4LO. The front wheels slipped quite a bit when pulling, and I believe I understand why the torsen differential did that due to the varying amount of friction between the front and rear.

Would it be better in this case to lock the differential to initially get it out of the water (50 feet in a straight line), then go back into 4HI to tow the rest of the way?

I realize a 2 ton+ load is towards the upper end of what my truck can handle, but following the ramp I only have to tow it 0.25 miles to the garage where we keep it. Any advice is appreciated!

In that situation, you’d probably have the best results just leaving it in full time 4 hi, unlocked. ATRAC will monitor and correct individual wheel slippage.

Boat Ramp story...

Differential lock on boat ramp?

A WDH might help keep more of the weight on your front wheels. I would think locking center diff would be the way to go personally.
