Crawler Innovations was the first to combine closed cell and open cell foam into one package. The Lil' Nova Foams have been around since the beginning and are made from the best compounds available. The Lil' Nova Dual Stage Foam design is for all high-performance applications where grip and traction are essential. Available in a variety of compounds and sizes, the Lil' Nova Crawler Foams are the perfect addition for your new tires.
Sold as a pair.
This is the replacement outer for the Lil' Nova 4.25, 4.50, & 4.75". The Lil' Nova Tuning Rings are also included.
These inserts feature a standard conventional or open cell density foam cut entirely from our Medium Outer Foam Material. This conventional foam is not temperature sensitive, but it is not water proof.
Approximate size: 5.125" Height x 1.75" Width

I run crawler foams in all my trucks. They do great crawling and these new extra wide foams fit perfect for my new boom racing wheels. Not much on the market for extra wide but these are perfect

Absolutely love these outers. Tough, durable, and resilient. I run a 7.4lb custom Capra based truck, (YouTube- GeardownCrawlerz Texas), that i put a ton of stress on. I get at least 10hrs run time on them under high demand, easily double that with light crawling. I've found that if you feel they're done, DON'T throw them away! Let sit open for a day or two and they regain structure, then use inside out. Great to have as an emergency back up.

I love these foams. The tunability is amazing, so many combinations you can try. Would not use anything else but crawler innovations Lil' nova's.
