5/14/2026 Update - Bronco Raptor APG ProRunner Suspension Installation

[SierraBronco]

These APG's weld-on pivots are custom chromoly tabs positioned forward 3-4" from stock for optimized anti-squat and pinion angle control under torque.

For these components they should be their own design and not off-the-shelf. The design is specifically to minimize axle wrap on launches/jumps while maximizing fore/aft stability. Ground clearance should actually improve 1-2" over Braptor OEM lowers thanks to the raised/angled mount, too.

If this were on a narrower tube chassis, outside mounting the would be ideal, but here I bet APG prioritized durability over likely marginal clearance gains...? Not sure, but I see what you're saying.

As for Johnny Joints...in the APG 4-link setup, the lowers/uppers are longitudinal (trailing-style) for axle location, but the coilovers mount directly to dedicated axle brackets/towers. This means not loading the Johnny Joints axially with spring/shock weight. For my mixed use setup of off-road + street, this should translate to quieter/smoother than heims while being fully re-buildable with 30°+ articulation without slop.

I don't mind the critiques of certain designs, no offense taken -- the good news is I will put design theories to the test because I will be driving the hell out of the Braptor and I'll post about it to for everyone to see results and learn from.

Hell yeah man! And thanks for the confirmation on some of the questions/assumptions.

Are they running stock length upper links or is the tank getting modified to accommodate longer arms?

12/16/2025 Update (Frontend is Complete):
King 3.0 Coilovers, King 2.5 Secondary Bypass Shocks, King 2.0 Bump Stops, double-sheer billet aluminum HD tie rods, APG upper and lower control arms, and even the Braptor sway bar are all completely installed. This setup re-uses the OEM Bronco Raptor knuckle, too.

I'll post pictures of the rear when it's complete. I'm not sure what the upper links look like; that's the one detail I haven't paid close enough attention to regarding how the longer arms are accommodated and whether any modifications are required. Rearend will be wrapped up in a day or two.

Appreciate the updates!

I’m sure they cycled the suspension to check clearance on every component, but the swaybar arm looking like that at full droop is messing with my brain.

Same here. That can’t be right. What happens to arm when suspension compresses? Can’t be the final sway bar configuration.

Found a photo with the wheel off on the OEM Braptor lower control arms with sway bar end links (taken when the Godzilla V8 was going in so not the same identical angle for the photo):

Agree it looks atypical but APG compared to OEM Brap is not looking directionally that different in terms of how the sway bar arm and end link is positioned at full droop in either photo.

I'll get videos posted once I have them as it would help a lot more to see the movement. Either way, yes, they are cycle testing the components.

Beautiful.

Looks like the factory (i.e. weak) cam alignment plates. Suggest a cheap/significant upgrade such as the BD Suspension ones:

Good call. I had the Foutz lockouts previously, never had alignment issues with all the jumping on 40's. Will add this to the list to double-check.

I added these (BDS) after the first outing jumping mine, steering wheel went crooked, since then nada.

@SierraBronco Video of the Dana 60 rearend installed with coilovers and bumpstops. Bypasses are still not in. You can see the upper link installed in the passenger rear -- it's tight around the gas tank, but no gas tank modifications needed.



And while we're at it, a profile shot of the rear:

@22broncoraptor If you already have the welded in Foutz slot delete for the lower arms, you don't need the BDS.

thanks for posting this!! And all the follow-up details, this is a huge help to me as I contemplate my suspension overhaul next year. So little info out there.


For reference purposes only, the Foutz mid travel linkage solution…. since they’re sticking with stock geometry it’s an easier problem to solve as evidenced by stock arm. I’d imagine with additional up travel and “straight” linkage parts, the riser from the LCA would have to be pretty tall compared to stock/near stock.

12/23/2025 Update - Suspension is completely installed

The suspension is completely installed and did the first shakedown run in Johnson Valley.

nice man. How many inches of lift did you end up over stock and what did the up travel/down travel come out to?

I'm not sure what it was stock, height wise as I didn't have the Brap stock for very long when I bought it and didn't think of taking measurements at the time.

But I did do some wheel well measurements (after the APG Fenders were on) when I had Hyperco 2" coils installed. There was 10" of fender to top-of tire clearance in front and 9" in rear. Overall Braptor height was 80" (or 6'8" tall).

The new King coils still have some settling to do as they are obviously brand new with low miles on them:

Front is 12.5" (2.5" taller than the Hyperco's):

Rear is 12" (3" taller than the Hyperco's):

Total height of the Brap is about 83" right now, so about 3" higher than when I had Hyperco's. So that's probably close to 7" taller than a stock Braptor on 37's when comparing this King coils setup sitting on 40's?


As for wheel travel, 17" front and 18" rear. Stock Brap is 13" front and 14" rear travel.
