So last year in September I contacted MaxTrac Tech Support because my front end lost some height front when I first got the 7" lift kit installed. I did understand that with time the springs would settle as expected and at this point it has lost an inch and 1/4 since then.
My front sits at 43.75" and the rear at 45" ... the rear has not lost any height but the front has ...
So MaxTrac Tech Support asked me for pictures of the "front spindles, rear coils, spacers, shocks, brackets, etc." ... which I sent them the pictures ....
I didn't get a response from them until 1/8/2021 and they said that I never sent them the pictures they requested, so I sent them again.
Today I got another email in which they asked for the "size wheels and tires, also the backspacing of my wheels".
So I sent them the requested information which is 20x12 wheels with 37 inch tires and a 4.77 backspacing with a -44 offset and asked them "What does the size of wheels, tires and back spacing have to do with the front end being much lower now ?"
The guy responded with:
I asked you about wheels and back spacing because "Deep dish" wheels are very problematic on these trucks. With the recommended wheel/tire set up, your suspension still maintains its factory 2:1 ratio. When you install a wheel that is wider than what we recommend and sticks out excessively, it changes the ratio of your suspension. Instead of a 2:1 ratio, your suspension now has a 2.5:1 or 3:1 ratio, which increases leverage on the coil, causing it to compress more and give less lift than intended. A 20 x 12 with 4.77" back spacing is what is causing your front end to sag. It has applied more leverage to the coil, lowering your ride height. Unfortunately, this voids our warranty and I highly recommend switching to a different wheel/tire combo. The suspension components on a Ram 1500 were never designed for the stress that wheel adds to them and can/will cause premature failure of factory and aftermarket suspension parts.
Thank you,
Does anyone agree with the response they gave me and if you go look on their site it says 4.5 to 5.75 of backspacing ... my wheels have a 4.77 backspacing lol ... how does that void the warranty? Took them over 4 months to give me an answer which contradicts what they have up on their site... or am I not reading this correctly? lol ...
So for anyone who is thinking about getting a MaxTrac lift kit according to their recommendations their springs will not hold up if you use wheels that have 4.77 of backspacing when the clearly state that a 4.5-5.75 backspacing is recommended.
So if your front end is losing height according to them wider wheels that stick out "excessively" changes the ratio of the suspension from the 2:1 ratio to a 2.5:1 or "3.1" ratio which increases the leverage of the coils causing the front end to sag .... WHAT ! ....
Below is what is posted on their site.
So I guess I will need a higher rated set of coil springs for the front or add the 1" coil spacer now? ...
Now don't get me wrong you guys I am not bashing the lift kit, I love my MaxTrac lift kit and I always let everyone know about how good of a lift kit it is, but this response from them just doesn't make any sense.
However, the owner of the shop where I got my lift kit did agree with the response they gave me but to say the warranty is completely voided because of the 4.77 backspacing is just BS lol ....
So be careful of what wheel set up you guys put on your trucks with this liftkit because according to them it will definitely void the warranty.
