Anyone using Timbren rubber helper springs in the rear with 1250 lb WD tongue load ? I just traded my 2000 for a new 2003 6.0 PSD 4x4 Limited and was thinking maybe Timbrens might work instead of the airbags.
OK. Hooked up the trailer this morning. Put 950 lbs. on the tongue (weighted it with my trailer scale).
Unloaded, the bottom of the receiver hitch on the X was at 16-1/2". After loading, it dropped to 14". I cranked up the weight distributing bars and got the bottom of the received back to 15-1/4". The tank is empty, so putting in another 40 gallons of fuel might make it drop a bit more.
I also measured the front at the tow hooks. 24" before and after torquing the weight distributing bars.
The rear Timbrens were sitting on the leafs, although it is hard to say how much compression there was. With no load, there is about a 3/4" air gap between the rear leafs and the Timbrens. The front Timbrens always set on the leafs.
I suspect that the rear Timbrens are why the rear end only dropped 1-1/4" even with a load on the rear (probably not 950 lbs. after cranking up the weight distributing bars). I drove around the neighborhood a little to shake things up so that I can check everything out. The truck ran pretty smooth.
According to the Timbren web site, your Timbren's are rated at 1500 lb's per side for a total of 3000 lbs ability on the rear, of course, don't exceed manufacturer's GVW [img]/ubbthreads/images/graemlins/wink.gif[/img]
Thanks for the info. I kept my receiver height at 18" (inside top of 2" opening) on my 2000 so I will get another pair of Air Lifts since I will be at the maximum 1250 lb WD tongue weight. I still have the front Air Lifts and rear swaybar since I did not install them on the 2000. I would like to keep the receiver height between 16-18" to not let the tonge load go over 1250 lbs.
My new one came with E rated BFG ATs so I can put 80psi in the rear to have 6,830 lb tire capacity on the 7000 lb rated rear axle. But I don't even think there would be 6000lbs on the rear with the 1400lb spring bars set for maximum WD.
15-1/4" was to the BOTTOM of the receiver, so 17-1/4" at the top, if that makes any difference.
I can play with my tongue weight pretty easily because I haul cars (I have my heaviest in there now). I just move the car back and forth to get it where I want it.
When I first loaded the car this morning, tongue weight was at 1000 lbs. I pushed the car back 6" and put my tools in the back of the trailer, and the tongue load reduced to 950 lbs., which is good enough. I figure that I am running well below 900 lbs. with the bars drawn up. I don't want it much lighter than that.
I drew the bars up pretty tight. 15-1/4" is all that she was going to go. I might back off on the bars some.
This is my max. load, so if this hauls well, everything else will be a breeze.

No. The rears are rated at 3000 lbs. per side for 6000 lbs. total.
Now, the fronts, yes, they are 1500 lbs. each, 3000 lbs. total.
You are absolutely correct, I sit corrected, was looking at the wrong column (front) [img]/ubbthreads/images/graemlins/sleepy.gif[/img], so he does have an extra 6000 lb capacity on the rear.
