LR3 laser chain aligner (ref. R3-1043) is a precision tool designed to guarantee the perfect alignment between the crown and the engine sprocket on competitive karts equipped with chain transmission. It uses a high visibility laser system that allows fast, accurate and reproducible positioning without approximation.

Why this tool is indispensable

Misalignment of the chain can result in:

• Side rubs

• Premature usury of the chain, pinion or crown

• Loss of mechanical efficiency

• Overheating and greater engine stresses

Thanks to this laser lineer, these inconveniences are eliminated, providing a more fluid transmission, a better motor response and an increased lifetime of components.

Technical specifications

• Reference: R3-1043

• Type: Laser Chain Liner

• Integrated laser system: Yes
