In my words

1.9 Single Stage Closed Cell Crawl Foam Insert2 is bench hardware: dull on the shelf, loud on the track.

The set runs 1.9" across. Shock geometry changes a car more than a spring swap, and swapping a tower is cheaper than both.

Sizes and colors come and go on this one; the listing shows what is actually in the box today.

What Pro-Line says about it

  • Contoured to perfectly match Pro-Line's 1.9" XL Tires
  • Extremely Durable
  • Lightweight and Waterproof
  • Provide unmatched Sidewall Support
  • Deep Grooves for More Grip

Questions I get about this set

Aluminum or plastic?

Aluminum holds geometry and transfers the hit; plastic bends and comes back. On a rough outdoor track I take plastic in the front and aluminum in the back.

Do I need special tools?

A hex driver set that actually fits, thread-lock and a bench. Rounded hardware costs more time than any part on this page.

Very firm foams, fit stock TRX4 wheels/tires well

It is a very hard tire foam- Using it for trail running and water crossings on a TRX4 with the original wheels and canyon trail tires and fits perfectly. Waterproof is a big perk, but probably not the best for rock crawling with a stock relatively lightweight rig.

Must have if crawler is heavy

No more “flat” tires and if you have good tires, traction won’t be an issue! Fit well and works great on heavy rigs

★★★★☆

Very firm, but Must be good, lots of crawler dudes use these ?

After reading many reviews about this being a great crawling tire, i took a leap and tried them out. Well, i intended to until i received the packed and felt how hard they are. Thinking maybe i got a set that may be a bad batch i contacted the seller and was told that was normal. Not knowing the firmness made that tough to judge. Without a durometer reading or something objective to relate it to, i was dissapointed qnd regretted my purchase. Seller was accomodating and refunded my order. I paid to return them as i was at fault being ignorant and not researching more about what to expect. My review is more of the overall Fair and positive transaction because the product doesnt suit my needs.

trx6

they are pretty stiff you will loose a little tire conformation but its not too noticeable especially with the massive gain in side hill ability not having the tires roll over onto the bead. also added more high speed stability my trx6 can actually turn now at speed without just flipping over

★☆☆☆☆

Not good for rc crawling. Mud bogging maybe.

Ordered to use on my rc crawler for some creek crawling but after testing them realized they were way to stiff to use for crawling. No flex at all and my rig weights 7lbs+. They could be used on a dedicated mud bogger where flex is not a necessity and where you plan on submerging the wheels in water or mud all the time. As for creek crawling not worth the loss in grip/flex. They remain on the shelf.
