Can you measure the total height from frame rail to end of the rubber.
Id like to see how far it will come down with my lift

will do

Thanks for all the help, I plan on ordering the timbrens in the next week or two.

Just giving you a hard time. That's a long sum bich.

Yeah, I figured. It was surprising how well it handled it. But my dually just came in yesterday. So the 250 will get traded in.

Think Im going to order some Timbrens for my 13 tomorrow. Cant be bothered to run airlines and bags if Im going to sell it soon anyway.

Not sure which timbrens to go with tho.
Im finding 2 compatible part #s.
Can anyone with them post the part# you went with.

I just put the new airlift air cells. They're like timbrens but half the price. I'll let you know how they do.

I am using the Sumosprings with 4k pin weight and very happy with them. Ride great, nothing to go wrong. There softer then timbrens so the truck will squat an extra 1/2-3/4" over timbrens but even hitting huge bumps the rear feels really good. You don't get the kick like you do with timbrens. With 4k lbs the rear squats right about 2-2.5"

only time i get any kick is unloaded on gravel roads.. ride is fuggin awesome when towing. can be a lil harsh on gravel or a really chity paved road. just feels like a normal 1 ton to me though. not a sissyfied version as they are now.

I'm in love with the air cells. Ride way better than the timbrens. The bump stops kinda snap in the bracket for them. I can swap them out in less than 5min. Snap off the bumpstops, zip off the bracket with no need to jack the suspension up. And they're off. It seems in this pic I'm squating, but I didn't add the extra spacers I needed to make it level. I'd rather have more travel after I unhook the trailer while camping.

Truck would ride on the stock bumpstops with this trailer (Deaver springs are to blame)

I'm located in southern Illinois and will be towing through hills, how well do the timbrens work? I feel like I "need" more power too, actually just want to delete. Is there any place in southern Illinois?

Where are you located in southern il? If you want to see an air bag set up and how simple they are we can meet up some time. I couldn't do with out mine. This is about 3500 lbs in the bed. A rear away bar would be helpful sometimes though.

I'm towing a 5th wheel with a tongue weight around 3300 lbs. I stupidly did not get the camper package and just have the 2-1 springs. Any advice for this noob would be appreciated, I really don't want to do air bags. Should I do an add a leaf, or maybe look for f350 springs? Any vendors have a good solution? I got the 10k gvw with factory rails and a curtain q20 hitch. Toy hauler weighs 12750.

You're complaining that the rear has soft springs but did you ever bother to check your available payload? It's a giant yellow sticker on your driver's door jam.
I'd wager you're easily a 1000lbs over. You're likely over weight for even a SRW 350. Should have bought the right truck configuration.

It's strange that a 3/4 ton crew gmc duramax squats much less then my rev cab 3/4 ton Ford diesel. Even if both are overweight.

It's quite simple, the rear of the ford rides better because it has softer leafs. Install airbags or airless bags and done.
