I’ve got these running in my Capra sitting on 2.2 SSD Assassins (Blue rings for prolines), and Proline Hyrax LP (G8) compounds.
These things are AMAZING!!! The fit really good. The side wall is solid enough to lift the truck without the whole tire folding in on itself! Easy to install and shipped fast! I’ll definitely be ordering more sets on different rigs!

I bought these in 137mm put them in my pit bull rock beast 2.2 XOR.
With initial testing they are great definitely will buy more.

I’ve tried no less than 12 different brands of anti-foams/inserts and these are hands down the biggest improvement and most consistently supple across the entire diameter. You can actually side hill with these too! And since you can get them made to your exact tires specs they literally fit like a glove and assemble is a breeze!!!
If you have a rig you out in mud/water these are a must with vented tires.
I’m up to 6 sets of Squids so far. I can definitely say that all new sets of tires will have SQUIDS in them!!!
I’m excited for the SCX6 – 2.9 inserts to come out. That model in my opinion will gain HUGE benefits over stock & even Proline dual stage foams

Totally blew the ordering for the inserts for my 2.2” Proline G8 Super Swampers – did not read the sizing info and ordered the wrong size – notified Neal and he contacted the Post Office, they found the box and he went down and swapped out the inserts to fit – total class – I am a total convert – best products, best service – devotion to customers – absolutely outstanding!!
