@Peak Suspension
Entertaining the idea (if its necessary to prevent top hat failures) of running the Peak rear spacers (1" lift), front lower spring spacer (1" lift), and a TheTacoGarage billet strut reinforcement plate (1" lift).
On paper that would result in a 2" lift in the front and a 1" lift at the rear.

Any update whether this front setup would work as expected (2" front lift while preventing top hat failures)?

I didn’t end up with that set up. On an older post from thetacogarage, they said that their reinforcement plate is a 1/4” thick at the base (not including the part of the plate that’s machined to go over the failure point of the stock top hat).

so with that in mind, and seeing how the peak top hat spacer is ~15mm thick, i wasn’t positive I’d be able to achieve that 2” lift from the proposed combination of front end plates.

Here’s my thoughts on this. Any preload spacer is going to move the equilibrium position of the shock valving closer to the bottom of the tube. This will cause the shock piston to need to travel farther and compress the spring harder in order to bottom out. This won’t “prevent” top hat failure but will require a much harder hit in order to cause a failure than it would in stock form.
I just received the Peak 1” preload spacer and a 1” rear and 0.75” top hat spacer from another company. Should give me 1.75” front and 1” rear. I don’t bag my truck off-road, but should give me some more room to absorb a hard hit without hitting bump stops. And maybe a little more peace of mind that I’m better than stock.

The way the front suspension works for Tacomas in the past, and the 4th gen isn’t an exception, the top hat spacer thickness does not directly correlate with how much lift it will actually have on the truck once installed.
So with the 1” preload spacer, and the 3/4” top hat spacer you plan on getting, it will not give a 1 3/4” lift.
The peak 2 piece front kit is a 1” preload spacer and a 15mm top hat spacer that translates to a 2 1/4” front lift.
If you were to attempt the 3/4” top hat spacer, it’ll be more than 2 1/4” and not to mention you’ll likely run into stud length issues previously mentioned by peak customers.

Yeah I’m aware of the suspension ratios. The top hat spacer I have is 3/8” thick so I won’t have stud length issues and it will indeed give me 3/4” of lift. I just call it (maybe incorrectly) a 3/4” spacer because that’s how much lift it will give me.

It seems the suspension geometry is such that actual front lift is ~2x the thickness of the top hat spacer.
Given that, a Peak 1" preload spacer combined with the 1/4" tacogarage top plate would only give ~1.5" of lift. Not sure why tacogarage claims the top plate gives ~1" of lift. All examples of top hat spacers (which the tacogarage top plate reinforcement is equivalent to) doubles the thickness as it translates to ride height change.

I really like the idea of both having ~1" of lift AND top hat reinforcement in a single piece, but wish tacogarage was more accurate/honest on the resultant lift from their top hat reinforcement plate.
Anyone know of a ~1/4" (6mm) top hat spacer I could use in conjunction with the tacogarage top hat reinforcement plate? That would result in ~12mm of "spacer" translating to ~1" of lift.

What brand/model is your 3/8" spacer?

Mine is the Cornfed 3/4” (3/8” thick) top out shim. David was really great to deal with.

ATH Fabrication has a shim that gives 3/8” of lift which might work on top of the Tacogarage lift. https://athfab.com/product/3-8-lift-spacers-for-2024-fourth-gen-tacoma/

Thanks! Looks like Cornfed has a 1/4" version of the top plate also, which combined with the tacogarage plate, is 1/2" total thickness, giving 1" lift. Combined with the Peak 1" pre-load spacer, that should result in 2" total lift with a touch more thread left on the top hat bolts than the 15mm Peak spacer.
I wouldn't mind the 3/8", but I lose about 1mm of thread over the Peak setup.

Right, I forgot Cornfed had a smaller plate for 1/2” of lift, that would probably work too.

It's also worth noting how the top mount failure was achieved in the first place. If you jump your truck with stock suspension or stuff it into whoops incorrectly, the top mount failure can happen, regardless of any type of spacer lift combination or none at all.

With the internet, failures always seem to be more prevalent than they actually are since it tends to be an echo chamber for reporting problems or complaints, so it's always worth keeping those thoughts in the back of your head vs worrying about it all the time.

We see this time and time again with other makes like the Bronco and it's tie rods for example, usually resulting in driver error more than a part or manufacturing failure.

IF it does ever become a problem or that Toyota deems it to be manufacturing issue, they will without a doubt fix or remedy the problem.

I'm definitely not taking my truck to the Baja 1000 or anything remotely similar and fully understand the tendency for problems to be highlighted on the internet. This is just cheap insurance if I'm already doing some suspension work up front, knocking out 2 birds at a time, even if one of those birds is just a sparrow.
Appreciate the chiming in and level setting.
