Crawler Innovations Lil Nova 4.0 1.9" Class 1 Crawler Foam (2) (Standard/Soft)
The Crawler Innovations Lil Nova 4.0 1.9" Class 1 Crawler Foam was developed for SORCCA competition using Class 1 tires ranging in height from 4.19" and smaller. This foam was designed to not over stuff the class 1 tires the way the 4.25" Lil Nova does. The 4.0" Lil Nova was designed for 6 pound and lighter weight rc vehicles, focused on scale rc crawling performance. If you have a heavy rig and need more support from your class 1 tire, the 4.25" Lil Nova is better suited for that.
These inserts feature a standard inner foam, with a soft density outer foam. The closed cell inner foam fits .750" wide bead locks, is super dense, water proof, is not temperature sensitive and is extremely durable. The conventional outer foam is not temperature sensitive, but it is not water proof.
Typically, you want to use a firmer foam in the rear than what you use in the front. This will help to prevent the truck from lifting the front end when climbing obstacles or steep grades. Additionally, the heavier the truck, the firmer insert you will want to use. Package includes two foams. Foams are also available in medium (CWR-2092) and firm (CWR-2093) densities.

These fit perfect in my class 1 Proline Hyrax tires. I am not sure why the other reviewer is having so many fit issues.

Crawler Innovations Lil Nova 4.0 1.9" Class 1 Crawler Foam (2) (Standard/Soft)
Pretty disappointed with these. Looking for some dual stage foams for my UTB18 Capra & I hoped these would do the trick. I’ve tried them in half a dozen tires & they don’t seem to fit any of them very well. I’ve tried them in 3.85” tires up to 4.19” tires & they don’t work good in any of those tires. They seem like they would be ok in a 4.25” tire with a very light vehicle. They would need a lot of modifications to get them to fit well in any tires from 3.85-4.19” size.
