Racing 1.9 XL Dual Stage Closed Cell Crawl Foam Insert2 PRO617400 RC Tire

Fantastic! Worked well!

Great sidewall support and super squishy for great tire form going over terrain.

My Gen8 is now 9 1/2 pounds. These work very well for rock crawling which is all I do with it. With some rims they will the inner foam will slide from side to side. Not a big deal. They are a little wider than some of their competitors and not as tall in the tires. They are far better than any single stage foam I have tried.

I like these two stage foams but gave them 4 stars only because they are a little too big for the proline tires I already have. Other than that, I’m sure they will be perfect when use while the perfect size tire.

I normally would not say this about Proline foams, But at 8$$ now 11/1/24 a set instead of 20$ like they have always been. There dam good. Most people will agree that duel stage inserts are some of the best light weight traction +side hilling achieved as long as you keep them away from the water......I have been taking advantage of this price for all my wore out inserts before they go back to a ridiculous 20$$a set.

These tire foams are great I installed them in my Pro-Line Hyrax 1.9 tires on my TRX-4 they made a instant difference in the Rigs performance I highly recommend them for trail and Crawling . I do have to say these are not 4.1 size they are 4.75 .. I will be buying more of these

Just what you expect from proline

These foams have helped boost the preformance of my Gen8. I got these to replace the stock foams on my Duratrax Showdowns 4.75 tires. I felt the foams were initially too stiff for my liking, but an explanation from my local hobby store helped clear it up for me and I now love these foams. The dual stage foams help a ton with side hilling, and help make better contact. Both are big advantaged for me

Great product

Best foam ever made ever in the history of ever

I had to modify my dual stage foams to work well with my Treal wheels. (or any others with smooth flat surface beadlock rings) When assembled there is no groove in the beadlock rings for the center part of the inner foam to lock into. So then the foams shift from side to side when a load is placed on them. To solve this I cut the center ridge out of the inner foam. I then placed double sided carpet tape between the blue and white foam and inserted them into the tire together as one piece. Then I put carpet tape on the outside of the beadlock ring and inserted it and centered it before the tape got a good hold of the blue foam. Now there is no shifting of the foams inside the tire when a side load is placed on them.

My package came already previously opened and one of the inserts had damage to the inside of the insert making it useless for the intended purpose.

Works great, side-hilling is way better, just take your time setting up the dual foam, if you go to fast or don`t set them proper the tires will be wonky, and look bent out of shape
