Well. I learned something new today. I was unaware you could not align the rear. But after some research...sure enough. Unless the rear axle has been knocked lose there is no rear end adjustment ever needed. Thank you sir. Good to hear about the ride quality also.

 

Really need some input....
I have installed Fox 2.0 all around, with their coil over front struts.
Unfortunately the front end is now 5/8"+ higher than rear.
Before lowering the front to to be level or maybe have slight rake, I'm trying to determine if the rear end of the truck/leaf springs are lower than it should be for any reason, and if I should address that first, and how.

REAR: center of wheel hub to bottom of wheel well is 23-3/4" empty.

2017 Lariat SuperCrew, 4WD, 2.7 with retracting canister tonneau bed cover (100 lbs?). Leaf springs are the lightest spring rate #A of the 4 OE spring rates available. It has tow package but not Max Tow or HDPP. Doesn't even have an electric trailer brake.

Unfortunately I don't have the original measurements so I can't compare what it was originally, but that probably doesn't matter. I know there was at least 1-3/4" rake with OE before Fox install.

 

I do believe what I'd do, seems the easiest, is just get a 2" block for the rear

 

Learning about it and considering options.
I'm wondering if my rear end is lower than it should be due to damage or if the leaf springs have been bent/flattened?
They don't appear to have much curve?

Then I'd see what options...add a block, add a leaf, lower front, etc.

Haven't had experience with suspension, it's mostly new to me.
I don't know where to find the rear height info, if it exists in a format that I can apply.

 

They are all gonna be different heights unless you find your exact twin truck (with the same amount of gas too).

My measurement is 25.5 with stock rear suspension minus the Fox.

your options are:

-replace your leaf pack with OE and hope you get some lift back.

-add a leaf

-buy a new leaf pack with a 1 inch lift and hope it doesn’t net you 2-3 if yours are bad

-add a RAS which will lift, support, help with ride quality, and is adjustable

-add a block

block would be cheapest and easiest, followed by the RAS, then add a leaf, then OE leaf springs, then aftermarket like Deaver or icon.

 

Really helpful, thank you.
I guess there may not be an easy way to determine in my leafs are weak/bent.
I like the idea of doing anything to improve ride (upgrade vs repair).

What would differences be adding RAS to new springs vs flattened/worn/damaged springs?

 

Take a rear wheel off and send us a pic

 

New leaf springs from tasca are $380, plus you can get a beefier spring and find them cheaper than tasca.

id go that route if I was that convinced.

 

Not good enough perhaps, but this is a pic I have, jack is under the axle, no jack stands. I was thinking the leafs were fairly flat when I was taking the pic.

Disclaimer: The ground in this photo isn't level, the truck is parked on a slope with the front facing upslope, so maybe the rear is pressed down a bit more.

 

First, let's get some point of reference for the front setup. Is the ride height of the Fox coil-over front struts set to any "stock" ride height? or were/are they set to, say, a "1-inch lift", or 1.5" or 2" (like Bilsteins can be). If not, then, the spring rate is higher, which means you'd want to have or create an "effective" rear spring rate increase for balance.

I'm going to suggest the Roadmaster setup. It'd be about the simplest (labor wise) way to go about getting some rear ride height - and - a slight increase in the effective rear spring rate. Others here have mentioned RAS, and I've been using the standard (not any HD) kit on my 2016 for 6 years and love it.

I do recall seeing with my original setup the rear leaf pack looking "flat". I think this is due to the very soft spring rate. You'll like the RAS. I can almost guar-ahn-tee it.
