Boom Racing 1.9" Class 1 4.19" Dual Stage Foams
Boom Racing 1.9" Class 1 4.19" Dual Stage Foams
Dual-stage foam inserts for 1.9x4.19" (106mm tall) RC Crawler tyres. They are a firm inner closed cell foam and soft outer open cell foam. Soft outer foam provides traction for the tyre to sink into the surface for more grip. A firmer inner closed cell improves side hill performance and maintains a better sidewall structure. The firm inner foams are more durable and longer lasting.
