Crawler Innovations Lil Nova 1.55 Crawler Foams are made from the best compounds available, design for all high-performance applications where grip and traction are essential. Available in a variety of compounds and sizes, the Lil’ Nova 1.55 size Crawler Foams are the perfect addition for your new tires.

These inserts feature a standard inner foam, with a medium 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.

This particular 1.55" foam was designed for use in the Pitbull Tires 1.55" Growler Tire (PB9005NK) and will fit other tires that are 4.25" tall.

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 soft (CWR-2001) and firm (CWR-2003) densities.
