Factory Pro FP-M-AC3020LB Light Blue 3mm x 2.0t Collar Set 10pcs  [FP-M-AC3020LB]

Accurate 3mm Light Blue Collars for Setup and Alignment

For modelers who obsess over setup, the Factory Pro FP-M-AC3020LB 3mm x 2.0t Collar in Light Blue is a small but useful upgrade. The pack of 10 lets you trim up clearance and alignment tasks across steering, suspension and transmission interfaces.

Why these shims work well

These light blue collars give uniform spacing to keep components running true. Whether you are adjusting suspension travel or getting gear engagement spot on, the thin 2.0t profile reduces unwanted movement without weighing parts down. The 3mm bore fits many common RC points of contact.

Where to use them

Factory Pro shims suit a variety of models and styles, from nimble on-road cars to modified off-road kits. They are especially handy for tightening up gear mesh and reducing axial play in rotating parts, which helps maintain smooth operation and prolongs parts life.
