HPI Racing Molded Inner Foams are original equipment on the rear of the Baja 5T line of 1/5th scale trucks. These are moulded foam donuts that help support the tyre for stable performance. The "MS" compound is strong and durable, especially important for proper performance on the rear of the Baja 5T. If your stock molded inner foams are worn or damaged, these will restore grip and handling to the truck. Sold in pairs.
