The Factory Pro 5mm Collar Set in red gives model builders a compact selection of spacers for modest setup changes. With 0.5mm, 1mm and 2mm options, you can step through small geometry changes to dial in handling.
These collars are useful when adjusting shock positions, toe shims, or small wheelbase corrections. Each thickness is supplied in a pack of five, enabling matched placement across both sides of the model or several cars in your box.
Designed to work with a wide variety of chassis and axle types that accept a 5mm collar, these spacers are versatile and the red colour makes them easy to identify during trackside tuning.
