Keep that weight down LOW!
While it may may look like a normal crawler wheel from the outside, Proline’s latest RC crawler wheel inserts include brass weights that are on a bearing, allowing the wheel to rotate but keeping the mass as low as possible.
Built for serious 1.9″ crawler setups, and working with most 3-piece beadlocks (including the SCX10iii and TRX-4 platforms), Rock-Tek offers a tunable 208g base system with optional add-on weights for precise performance dialing. Drivers can run magnetic stabilization for maximum control or allow free-spin behavior for adaptive terrain response, all while maintaining a clean, scale look inside standard beadlock wheels. With broad compatibility, hidden integration, and advanced weight management, it stands out as a smarter, more efficient upgrade over traditional brass solutions.
