You might love this. The 3500 chassis cab has a completely different set of rear springs than my 3500 DRW pickup. I have included a photo of chassis cab rear spring that shows NO bottom overload. My 3500 has top and bottom overload. This ingenius idea was on drawing board for quite a while. I came up with the idea to purchase 4 expensive solid plastic wood splitting wedges (4 bucks a piece) I slid the wedge into the spring set above the bottom overload. Before placing the wedges I drilled 2 holes completely thru the wedges for 4 heavy duty zip straps. They had to be HD because of the HD 3500. Now with load applied the 3 main springs will contact the overload sooner. I plan to tow the 5er tomorrow for a week long trip and will give it a test. This setup will not break your budget. If I don't like the ride pull out the nippers and cut 8 zip straps and pull them out. Ingenius right? Go ahead and call me an idiot:-{} It also gave me an inch of lift. 3500 Chassis cab rear springs 3500 DRW pickup rear springs
Where did you get the wedges? wonder if they will work on my single rear wheel? I may go with the timbrens instead of the airbags when I get the 5th wheel. I have to get the thing before I can tell. 4 weeks and counting.
Now you just have to find the black wedges. I bet they can be found for a little less! You must have paid a ton for that orange!rotfl
The wedges are "Stihl" chainsaw wedges. Just made a 125 mile trip pulling the 5er and they did well. Much softer than the Timbrens I had 2 years ago. Spray them with truck undercoating and you got black ones and would also serve as glue. This could put Timbren & air bags out of business.
how long are the wedges? I was looking on ebay and saw some that are 5.5, 8, 10, and 12 inches long. Yours look like the 5.5 in but I didn't know it they may have been the 8 inch long ones. Thanks, Chris
