Does changing springs and ride heights void factory warranty, especially since it sounds like we need to add camber bolts for an alignment? I purchased the extra Ford warranty and don't want to void it, but I really want to do some mods like the front and rear springs.
I also have 100k warranty- anytime you mod a vehicle there’s the CHANCE that the modification could cause a problem down the line where the dealer could use the mod as means to justify denying warranty coverage. Anytime you mod anything on vehicle that it wasn’t originally designed to have there’s also the chance you wind up w/ some “compromise” - improve performance/looks in one area but maybe sacrificing in another- that’s why you gotta really think ahead of time what you plan on doing w/ the vehicle, what performance/aesthetic goals you have & from there prioritize what you’re willing to do.
That being said- most dealers won’t even recognize the different springs- especially if you paint/powdercoat black to match factory. The only things that I can think of that may break/wear prematurely that you’d be leaning in an extended warranty for when it comes to front springs/rear leafs would be wheel bearings mainly & I don’t see a dealer giving you a hard time.
I think the “risk” is well worth the reward.
When it comes to engine performance stuff & warranty I weigh things similarly- I won’t putt a catch can, a huge FMIC in front of rad, or a CAI on my truck- BUT I will put a tune on it, why? Those other mods are plainly visible, require cutting/drilling/removal of factory parts, don’t necessarily even equate to performance gains, are very expensive for what you get in return, & the dealer will have every right to screw w/ your warranty on a mod like that unless you go to the extremes of de-modding & in the case of Catch can or FMIC there’s no going back to full stock unless you have spare factory parts on hand. Tune on the other hand can be removed completely (yeah could see a trace blah blah - unlikely they go to that extreme) & w/ something like these eibach springs, deaver/icon leafs, a stock mount located CVF, Wagner or whipple IC or hell even something like replacement Timken wheel bearings- while “mods” they all are designed specifically for the truck & get installed in stock location w/o any other alterations - so I feel it’s much lower risk of having a problem.
I really bought the extended warranty for the infotainment/tech stuff, the panoramic sunroof, the transfer case, the lighting, & cam phasers maybe being the only engine concern.
