Add-a-leafs

Over the winter, I plan to go through the suspenion on my 87 1/2 ton 4wd. Not looking to lift the truck really, mainly just firm up the springs some. Original springs are in decent shape and are not broken. I plan to put new bushings on the springs/shackles. I will also be towing a car trailer to bring my drag car to the track, hence why I wanna firm up the back end.

Will I see any adverse affect to add-a-leafs front and back? Bouncy ride? Is a better option blocks (height increase only). Can you safetly use block on the front?

Basically, which one will do better for me? The add-a-leafs supposedly will give me 1.5-2in of lift which is fine. I'd like to put a slightly larger tire on the truck at somepoint but it'll be a driver and tow rig more then anything.

Suggestions?

Thanks guys
Nick

Re: Add-a-leafs

never use a block on the front they can come off the front they get presure from turning that the back does not see. If you use add a leafs its going to stiffen things up some but not bad unfortnitly this is one of those things that depends on how the truck rides now you may find after there on you like the ride better or it could be so ruff it knocks your teeth loose.

+1 on the front end blocks! I lifted a Jeep CJ with add a leaves once. I said I would never use them again. The ride was much to stiff for me.

Re: Add-a-leafs

A 3000Lb drag car on a 1000lb trailer should only put 400Lbs tongue weight on the rear suspension, well within the limits of a half ton. the weight is effectively at the very back of the bed making it a bit worse, but IMO not enough to require heavy duty add a leaves like these http://www.hellwigproducts.com/produ...es/default.asp
which work great for much heavier loads, but really increase unladen ride harshness. I might suggest getting a rear dual shock kit, and putting in some air shocks. they don't absorb shock like a good shock, so they won't mess with your ride much, and they will level the truck out when loaded. Use 2 separate fill lines so all the air can't squish to the inside on long sweepers. You shouldn't have to mess with the front spring, you'll gain more from having all new bushings up there, don't forget the sway bar ones, they do a lot to locate the axle under the truck. Run tires with a stiff sidewall (higher ply count), and you should have a pretty comfortable tow experience.
My burb runs 265 70 16 tires with no rub at stock height. I've been meaning to post a pic, they fill the wheel well a bit better than the stockers.
