Please educate me on T/Boss level kit ?

[f8l vnm]

For you guys doing a 1-2 level kit on your trail bosses/AT4.  Would it be safe/reliable on all the components in the long run ?  What I mean is on my past GM trucks i know 2-2.25 is most you want to go on a level kit before stressing the suspension . With the Boss already being lifted 2 inches , is another 1-2 inches reliable in the long run ? And what makes this different then say doing a 2-2.25 level kit on say a LTZ ? where 2.5 inches is most you want to go ? thanks again

Watch this video from Ready Lift - the stock upper control arms geometry are stretched, so I would not level without a new upper control arm to correct geometry.

 

Lot of leveling kits that are just spacer which may result in issues down the road.  You can buy Ready lift SST leveling kit for AT4 or Trail Boss via Tire Rack - they have the best pricing I found anywhere and they offer Free shipping.  Cheapest good alternative - otherwise need to buy BDS for Baja Kits upper control arms, which are nicer, but also $400 more expensive.  

 

Just got Ready Life parts Friday - will go on next week when I have more time.  Will post up photos then.

Thank you very much! so figure parts labor/alignment about 1000-1200?

Yeah. I'm sure a lot of folks will ignore advice and do it the cheap way anyway. 

 

This picture says it's all. 

 

The geometry is way off doing it the traditional way.

Should take 2-3 hours labor to install - Parts from Tire Rack were $550 delivered to San Juan Capistrano CA (including tax, free shipping).  So figure $850-$900 parts and labor 

 

I have SVC Offroad in Irvine installing - they are Raptor and offroad shop that did my work on 2014 Raptor I have - great shop.  They quoted me 3 hours of labor to install - but if it takes less they will just charge the time it takes.  We plan to install front lift first - see how level it is, before installing 3" block in back (replacing stock 2" ones) - if back is lower, then will add block - but if level without black we will leave as is.  No rear blocks would save save half hour + in labor for sure. 

 

Will go in 2/7/20 - will post up photos after that.

Thanks for the info. Are you looking to still have some rake or are you looking for the complete level look ?

I am looking for the level look, but don't mind a little rake for aero/gas mileage purposes.  We will see what it looks like after front stuff goes on, then go from there.

Your upper control arms are already at a borderline compromised angle with the factory 2" lift, I wouldn't go any higher without aftermarket upper control arms.
