Hey i was just wondering if anyone had put an add-a-leaf on their 99 f150?
And if i add-a-leaf and crank my torsion bars would i be able to fit 33's on my truck?

 

if you have a 4wd you can fit 33's without doing anything. i would crank the t bars just to level it.

 

If you have 4wd you'd be able to fit 35s

 

If i where to crank the torsion bars and add-a-leaf would i need to get new shocks?

 

No.
If your truck is a 4x4 you shouldnt need an add-a-leaf to fit 33's, they will fit the truck stock.
If its a 4x2 you'll have a tough time getting 33's in there, but then again you wouldnt have torsion bars if you have a 4x2.

 

I did the front crank and add a leaf on my 97 4x4 and ran 33 Pro Comp AT on the stock rims. To complement this change I would highly suggest an upgade to a premium shock to round out the suspension. Stock shocks simply do not preform well after 50k in my experience.

No you can't fit 35's on a stock 99 4x4. You can fit 33's though. My truck has a 3 inch body torsion bars cranked and add-a-leafs and the 35's still rubbed a little on the very edge of the front bumper untill I trimmed it. Now they clear fine.

 

Ive got a buddy with a 99 and stock rims and he fit 35's.He cranked his torsion bars and had to do a little trimming, but they fit..although it looks a little stuffed....Ive got 33's with stock.

 

Backspacing has alot to do with it.

 

so if i ran 33x12.50 on 16in rims would i have any issues with an add a leaf and torsion bars cranked?

 

Well I suppose you could put a narrow 35 on a stock wheel and cram it in your wheel wells and it will fit but I doubt they function real great during all off road situations. 33's fit nicely, look good, and they still function flawlessly without rubbing in any circumstance on a stock 99 f-150.

 

35's will fit, but only on the stock rims. Youll probably have to trim the valence as well as crank the t-bars (although Ive seen a few people claim you dont have to do anything to them...cant imagine you get much travel out of the suspension without some serious rubbing).

You really dont need an add-a-leaf for a 33x12.5 tire. If you go with that size, mount them on a 16x10" wheel and crank the t-bars, you might have to trim some of the plastic valence. I would suggest doing this first, then, if you decide you still want the add-a-leaf, its not any harder to install it now.

 

do i need to worry about backspacing on the wheels?

 

Hey anyone that has an add-a-leaf and 33s how is the gas mileage on it? And would a hypertec chip be worth the money?
