Towing after Timbren Install

So what are your weights?

Truck Steer axle, rear axle (w/o trailer)
Truck steer axle, rear axle and trailer axles (w/o WDH)
Truck steer axle, rear axle and trailer axles (WITH WDH)


Timbrens ...like air bags just level/correct sag when hitched

But WDH set up provides correct tongue weight and control



Looking at picture...need to adjust so trailer is a bit nose down
BUT weighing is much better means of setting up WDH

That's a 26' body but a 30' trailer with a 9300# GVWR
Really need to go get weighed

you have a adjustable hitch, lower it a bolt hole. When you raise the front it changes the center of gravity to the rear and can lower the tongue weight and cause swaying.

Tires on your truck could be causing an issue also. They could be giving you a squishy/squirrelly feeling.

When I was towing heavy with my half-ton, I also added stiffer shocks and LT-E tires, in addition to stiffening the rear springs.

And spent a lot of time at the weigh station checking my weights and getting the WDH set up right.

So yes, it would be good to know what your WDH is doing. When you set it up, did you measure the front end lift before and after? Do the WD bars reduce the front end lift by 50-100%?

Your biggest issue is quite possibly the OEM receiver on your truck. Get under the bumper and you'll see in your era of truck GM relies heavily on the bumper mounting brackets for the weight carrying and weight distribution loads. That receiver design was used from '99 until I believe '08 or '09 when it was re-vamped a little.

What you need is a solid, frame mounted receiver like this Class V Curt Receiver that takes the bumper out of the food chain. My old 2004 Chevy 2500HD had issues with porpoising and just a slushy feel in when connected to the trailer. Once I installed a frame mounted hitch like the above link it all felt much more solid.

Okay thanks I already have load range e tires. I will try moving the ball down a notch. I don't know anyone with a scale so that isn't an option.

Any truck stop should have a public scale. When trying to solve handling problems when you're close to your vehicle's tow capacity, you really need to know your weights.

Go to most truck stops and there will be CAT scales. Costs very little (about $15).

Thanks, I will check that site out.

It looks like your trailer is nose high. It should be level. Your dealer may be able to provide you with the correct ball height. Also be mindful when packing. Heavy items should be between the trailer wheels and hitch.
