PRO616900 1.0" Dual Stage Rock Crawling Foam (4) (Micro Crawler) (Closed Cell Inner/Soft Outer)

Premium dual‑stage foam inserts engineered for 1.0″ rock crawling tires on micro‑scale crawlers such as SCX24. These foams combine a firm closed‑cell core for sidewall support with a soft outer layer for maximum traction and grip on rocks and technical terrain, while contours are precisely shaped to match tire profiles for better performance and appearance.

• Dual‑stage foam design for improved traction and sidewall support on rock surfaces.

• Inner closed‑cell foam core provides rigid support to maintain tire shape under load.

• Soft outer foam layer delivers maximum surface grip for climbing and articulation.

• Contoured inserts match the profile of 1.0″ rock crawling tires for optimized fit and feel.

• Four inserts included (two inner and two outer) for front and rear tire use.

• Lightweight foam construction helps maintain natural tire compliance and feedback.

• Waterproof closed‑cell inner ensures consistent performance in wet or muddy trail conditions.
