Is my lift and tire set up fine for off-roading?

Hello, i have a 2023 4dr 2.7L Black diamond bronco non-sasquatch. I bought someone's take off sasquatch suspension (similar model and engine). I only changed the suspension coilovers, no control arms or tie rods or whatever else. They had added 2" perch collars as well so it's a 3.2" lift overall. I then bought some 17" wheels with -10 offset and some 35" BFG ko2 tires. I had to remove front and rear crash bars to not rub. I measured the cv axle angle at street level and it is -10⁰ which i believe is fine.
Should i change out some other parts as well for support and longevity or am i okay

The way I see it, that's a lot of offset (increased scrub radius) and lift (spring compression). This doesn't mean you're going to go around snapping tie rods, but I'd keep some spares and a tie rod kit from TD Distributing onboard (@Tricky Mike).

In terms of performance, I feel like you're going to bottom out the shocks faster (heavier tires with negative offset and spring compression). I would avoid higher speed off roading like whoops. In situations where you need to drop into something with the front or rear ends, you'll likely hit the bump stops. Ride will feel a little rougher at the extreme end of the spring compression, since you've robbed Peter to pay Paul there.

In terms of longevity, all of those things put more stress on the driveline, steering and suspension components than Ford engineered it to withstand. I think it looks nice, but my build philosophy is more stay low, close-in and light with spring and suspension that stay within stock tolerances. YMMV.

Thank you for your reply. Is there some things i can upgrade to help the extra stress? I was thinking of taking the 2" perch collars off but that would probably cause the wheels to rub due to the negative offset. Is it worth trying?

Sasquatch springs? I doubt you'd need them. The Sas comes with 35" tires (well, close enough; they're also probably narrower than similar size 12.50's). Generally though, many have put 37's on with only a small wheel spacer or 0mm offset rims and max tire kit and had minimal rubbing. The -10mm offset is what makes me wonder, since that scrub makes it more likely you'll rub on the back with 37's (35's fine?). I see you pulled the rear crash bar already.

You could pull the perch lifts out and do some ramp testing, check full stuff and turn. I don't feel like you're doing yourself any favors off road that tall or stiff (preloaded) in the springs.

while I am no fan of - offsets or “perch collars“, your setup should be fine…you haven’t added any extra droop”, which is the CV killer…+2” running lift over sasquach with 35s isn’t really putting a lot of extra strain on components…just carry tie rods and tools…Party on!

Thank you for the reply! I don't do much crazy off roading anyways, so i think I'll be fine like you said. I'll get some tie rods and just monitor my vehicle over time.

Much appreciated!

That’s what I’ve been doing.

I think your entire reply is largely reasonable, that said, this bold part is pure speculation. Do you know the safety factors Ford used?
