Dirty Richard Single Stage Foam (Soft) 115x47.6x48

Sorry, this item is out of stock


Pit Bull Dirty Richard foams are an example of Pit Bull's commitment to improving the performance of your crawler and making the experience more affordable. Over a year of testing went into the development of the Dirty Richard inserts! The inserts are available in three different densities and are made to fit specific Pit Bull tires. Plus, they will work with other brand tires as well (Check Tire OD and Width prior to purchase).

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. The package includes two foams.
