This is a pack of two Crawler Innovations Lil’ Nova 4.75″ Dual Stage Crawler Tire Inserts. These inserts feature a comp cut inner foam, with a soft density outer foam. Crawler Innovations has brought a unique material and insert design to the crawler world that will dramatically improve the performance of your rig. The Lil’ Nova design features a closed cell inner foam combined with a conventional over sized outer foam insert.
The “Comp Cut” inner insert has three grooves machined into the area where the outer and inner meet. The machined grooves allow for the outer foam to collapse into them resulting in a much more responsive tire.
The 4.75 Size is the recommended for tall 1.9 size tires and heavier trucks. The Inner Foam Width fits 1″ wide bead lock wheels and the outer foam is Over-Sized on purpose to encase the closed cell inner, and to provide for weight support.
NOTE: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 transferring weight to the rear, causing the front end to lift 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 available in soft (CWR-2034), medium (CWR-2035) and firm (CWR-2036) densities.

Jeremiah Jaggers Verified Owner Sunday, Mar 13 2022 (about 3 years ago) Crawler Innovations Lil Nova 4.75″ Crawler Foam w/Comp Cut Inner (2) The tuning foams don’t stay on very well, making them difficult to install. Ron Verified Owner Tuesday, Mar 11 2025 (7 months ago) Crawler Innovations Lil Nova 4.75″ Crawler Foam w/Comp Cut Inner (2) I used to run CI foams and thought they were good. After not crawling for several years I switched to some SL3D inserts a couple months ago when I started up again. Unfortunately, I didn’t realize how great the SL3d inserts were, so I just setup a new set of wheels/tires and ordered CI foams (soft front and medium rear). There is no comparison, these foams are so firm the KM3 krawlers barely conform to rocks, the traction is so much less. I really don’t have a use for these foams so I’ll just eat the cost and get rid of them. All my crawlers going forward will be on SL3D inserts. 0 of 1 customers found this review helpful.
