Factory Pro M-AC3001BK 3mm Black Precision Collar Kit  [FP-M-AC3001BK]

Precision Spacing Collars for Accurate Setups

RC builders who want precise adjustments will appreciate the Factory Pro M-AC3001BK 3mm Black Collar Set. The pack includes collars in five thicknesses: 0.5mm, 1mm, 2mm, 3mm, and 5mm, with four pieces of each size. These spacers make it straightforward to tweak clearance and alignment across many parts of your model.

Compatibility and Durable Finish

The collars suit a wide range of RC builds from nimble on-road cars to heavier off-road rigs. The black finish looks neat on exposed areas and helps reduce visible wear over time.

Tune Handling with Small Changes

Using these collars lets you make repeatable, small adjustments that affect steering feel and suspension geometry. That precision is handy when dialing in handling for track days or general running.
