Timbrens on a 3500

Is anyone using Timbrens on a 3500 truck. I have a 07 Dodge 3500 DRW 4x4 with a BH3600RL. The truck is a little less than level. Wondering if theTimbrens would work. I really dont want air bags. My pin is right under 4k. Thanks for any info, Drew

Yep, I put them on my 2009 GMC 3500. Installed, there's about an inch of clearance without the trailer on. Trailer on, and I'm nice and level. Some will argue that the airbags give a softer ride, but I have not noticed any problem with the ride with the Timbrens, loaded or not.

Here is the system we have on the Ford. It is used to level the truck, but has no effect on the the stock springs. It effectively creates two suspension systems.
