up my 2wd suspension

Can I add a leaf and upgrade the front suspension on a 2wd 2003 Tundra 4.7l,
Or does that cause vibration issues?
Or is the whole idea ridiculous.

 

Yes, you can.

Vibrations wouldn't necessarily be caused by suspension upgrades, but could be caused by a sudden need to do suspension maintenance. Your ball joints and tie rod ends are working at a normal ride height, when you lift the front the angles change and now those joints may show wear that wasn't apparent before.

The real question is, what do you want out of your truck?

I also have a 2003 4.7 2wd and have done just about everything to it.

 

I suppose all I want is to take a little more weight, with a little more clearance., maybe a slightly taller tire
but then those questions might lead to a question of re-gearing..
then again does the rear end develop vibration from the angle from the add a leaf?

 

I live in a rural area , big bumps and snow drifts...
..what if I REALLY upgraded the front, say , with uca/lca and all necessary complimenting bits to a set of fox2 at the lowest setting...? ..or is that ridiculous ..

 

First, I recommend staying away from Fox on these trucks. King, Icon, ADS, Sway-A-Way, OME, Bilstein, anything but Fox. Fox has a unique and terrible design for these trucks. I have them and hate them.

Gearing isn't necessary up to a 33" tire (285/75/16 or equivalent). Any bigger than that and gears will be wanted. You can get gears just for fun, I run 4.56 with 33"s.

Rear end depends how much taller you're going. My leaf springs went up about 2" and settled to roughly 1.5" taller than the stock ones were. No vibration added, you can get vibrations from off road tires but thats part of the game.

Upper control arms are a good idea if you're planning 2" or more lift up front. 2" or less and they're not required but are still beneficial. I haven't seen stock length aftermarket lower arms for these trucks, stock arms are pretty stout.

 

Wow thanks for the knowledge!
Great insight.
I only want to go minimum as possible with a leaf, so 2inches would probably be max in the front.
So thanks, I'll start YouTuben those shocks on this truck. Cheers..

 

Listen to what he’s telling you bro saved me a couple grand
