Air Lift air bags inside your coils.You add air to haul up to 1,500# more.Air down to ride stock.

I have seen "helper" leaf setups on coil rears.

The helper springs [leaf] to fit the coils are expenxive....$350+ to get the parts and mounting plates. I'd go with air bags if it were me. Course you could just order 3/4 ton springs.

I didnt' realize they were that expensive. I took a set off of a short step with a bent frame. Glad I kept them now.

Re: How to beef up rear suspension???

went with overload shocks, shocks with coils over them. Didnt help much with extra weight but the truck handles much better around turns. If I were to do it again there is a kit that mounts air bags behind the original coils, not inside. Cant remember where I saw them but that are like to ones that mount coil overs

Re: How to beef up rear suspension???

make sure you have trailer brakes. i was told this was pretty much a must when you tow with a short wheelbase. but now that ive posted this im sure there will be people that say that isnt true...

Re: How to beef up rear suspension???

Another option would be a weight and distribution hitch with an anti sway bar. You would have to have a reciever hitch to use it. The weight and distribution hitch costs $300-$350 and the anti sway bar runs about $100. With one installed you can haul up to 10,000 lbs and run as fast as you want down the highway. You can buy them online or from any U-Haul or RV dealer. You'll also want your electric brakes hooked up too.

The Air-Lift bags are around $100,they give a 1/2t the load capacity of a 3/4t,or stock 1/2t ride when not hauling.I`d want trailer brakes for towing over 1,000#.

Re: How to beef up rear suspension???

I think you can order Air Lift air bags from Autozone.

I used to set up weight and distribution hitches all the time. I know a few tricks that may help keep your truck from sagging. But first, how many inches does it sag?

Re: How to beef up rear suspension???

hay,
My orange and white has 3/4 ton HD springs in the rear even though it is a half ton truck. Ive had over a half a ton of metal in the back and 3/4 ton of metal in my brown pickup bed trailer and the truck all most sits level. Riding empty it has a good bit of rake. Ride is fair but it might be do to the old nasty shocks but I am used to riding in stiff trucks anyway.

Re: How to beef up rear suspension???

The factory overload spring would help out alot. It wouldn't affect your ride one bit when not trailering.

I just purchased a new 10,000# equalizer hitch for $199. It is a Putnam brand. I was lucky enough to work 1 mile away from this distributor so I didn't have to pay freight. www.onetouch2you.com should be their web address.
