J, I added a toytec trd pro spacer to the front shocks. The upper strut mount bushing is stock trd pro. How is that modifying the stock part? The part that is broken is the bushing, not the shock itself.
You've modified the suspension, suspension geometry, loaded spring rate, and introduced stress to the suspension it was not originally designed for. Whether or not that is enough to just destroy a 4Runner's suspension is not relevant in the case of warranty applicability, simply the fact that the spacer lift itself introduces multiple stressors and variables into a system not designed for it and a failure has resulted in that system is enough for Toyota to deny coverage.
Understood. So this should mean, if I put rain guards on my car windows, and if my windows break, my insurance company shouldn’t warranty my window cause the rain guard is a 3rd party part on my window and may alter my window causing them not to cover it? I'll eat this one cause it is my fault adding the extra weight to the front. :doh:
If those rain guards fit into the window channel (like most do) and cause a situation where the glass is jamming into that channel and is tweaked to a point that it could shatter (rather surprisingly easy to do with safety glass if you apply stress the right way); then yes, warranty could be denied due to 3rd party accessories. But it wouldn't be your insurance company, it'd be Toyota; but they'd still have possible grounds to deny claim in that rare and convoluted hypothetical situation.
My Toyota dealer installs Toytech lifts. I asked them about my warranty. They said they will cover everything only if they install it and sell you the parts. The warranty on everything will not be valid at any other Toyota dealer.
We do the same at our dealership, we install lifts and tires and such. We warranty our work and work with the manufacturer if parts fail (word of advice, Bulletproof is a so/so product with really questionable warranty handling). So IF such a situation as the OP's occured and we had installed the lift, our dealership would probably either ask the DSPM to goodwill it or work through some channels to try and get it covered; or just eat it, not entirely sure how they get it done, but they'd do it. We've also had other dealerships pay for repairs because their spacer lifts broke a strut when the customer hit a pothole with their stock shocks an 37's on a Tundra.
I've been offroad many times with the spacers and never had an issue. The problem arose when I added weight to the front end (new winch & hybrid bumper), so the combonation of spacer and weight to the front did in the strut shock mount. Now looking to go OME BP51, its not available for the 5th Gen yet. Would like King Shocks but interested in trying the BP51's.
You're assigning a causality that is not entirely accurate. Just because you've been off-roading X number of times with a spacer lift, does not imply that Y possibility of it failing/stressing your suspension does not exist. It just means that Y is a small probability and unfortunately your luck ran out in this case. Additionally what spacer kit did you use exactly? The ones I've seen require replacement of the top mount or at least removal of the shock to install; that alone would introduce enough non-factory parts into equation to make any failure questionable from a warranty standpoint and denied.
Additionally the TRD PRO is actually fairly competent on the trail in stock form as it was designed. You as the owner introduced additional variables and assumed it should be good enough for additional weight and modified suspension geometry, which comes back to that causality thing; the majority of the time it'll probably be fine, but there's a small probability it could go pear-shaped... which it did in this case.
I'm not trying to beat you down here, just trying to point out the flaws in your expectations here. The MM Act isn't a get out of free jail card for modifying your vehicle, nor is there any reasonable expectation of warranty when you actively introduce parts & modify a factory assembly and it results in failure. That's not to say the bushing couldn't have failed because it was defective, but because of your modification, there's enough reasonable doubt and questionability that the factory is not obligated to uphold their warranty on that specific component.
