Trx4 Bronco- Foams for Hyrax preadator compound?

Hi,
I’m new here and just a couple months in crawling. I have a Bronco with brass portal covers and knuckles. Also have the lower shock mounts. Pretty heavy. I also placed sticky weights under the front small battery tray. I ordered ssd steel beadlocks and 1.9-4.19 Hyrax preadator compound tires. Are the stock foams good? If not what foams should I use and size? I heard to go soft up front and firm in rear. Proline 1.9 dual stages?

If it were me I’d go with these... Lil

Probably comp cut inner, medium outter in rear and soft up front.

I have the dual stage proline XL foams in the 4.75” predator hyrax and they work well, for what it’s worth.

Proline two stage foams are better, but I'm not sure if they offer them in 4.19 yet.

They don't, which absolutely boggles my mind with the tiny-tire craze. If they produced some 4.19" foams (single and dual stage), they'd sell like hot cakes. Missing some major sales here.

These are 4.15 but they have them listed as for their class 1 tires.

X2 about the Proline dual stage for the hyrax though, I’m very happy with them in mine. Just giving him options.

That’s weird, the description is definitely for class 2 but then they have this...

Specifications:
Height: 4.15" (105mm)
Width: 1.60" (41mm)
Outer Thickness: 0.75" (19mm)

Looks like an amain error?

Yeah AMain definitely has that spec wrong. Lookup that part number on Proline's site and it says those foams are for XL sized tires.
