Towing a 3800 lb Boat/Trailer. Z71 Springs worth it?

[c good]

Would it be worth adding the heavier Z71 springs for towing a 3800 lb trailer/boat combo? I will be upgrading to new Bilstein HD shocks also. It seems to tow the boat just fine, but I may be loading some more gear in the rear of the Envoy adding to the total. Just wondering if the Z71 Springs would be a good upgrade. Or would it make it too stiff for when I'm not towing? Thanks for any input. c good

I wouldn't bother. I think it would be too stiff plus it will lift up your rear a couple inches, and if you don't have a lift on your front then it'll be really weird looking.

If the rear sags too much, get a weight distributing hitch. Probably not a bad idea to do anyway.

I put helper bags in the back of mine. They go inside the coil springs and you just add air when you are towing. At 35 psi the rear of my truck is about 2" higher.

I like the idea of the air helper spring inserts. What brand did you get? Anyone else running these? If so any model/brand recommendations would be appreciated. c good

My total with the trailer is close to that, as long as you have the tounge weight right I don't really think it's necessary. Bilsteins help with bounce though.

I tow this combo with ease. Its a 22 foot Crest Pontoon and trailer weighing 4200 lbs. I have a 2007 TB 4.2L and 3.42 gear. I also use 3rd gear to tow in.

I helped my friend install bags in his Sierra 1500. He went with an Air Lift 1000. Install was easy. He tows daily and has never had an issue. 3 cubic yards of top soil in a dump trailer and the ass end didn't drop. His daily trailer is a V nose loaded with tools compressors, generators, not sure of the weight.

Do you also need some sort of switch/mechanism in the truck to fill the bags or let air out, or are they all manual at the bag site?

You can do both. I put in the airlift compressor and remoted a gauge and switch up front.
