Complete GY6 Engine Bolt Kit - M6

Complete GY6 Engine Bolt Kit for 125cc, 150cc, and 169cc Scooters

This GY6 engine bolt kit is meant for anyone working through an engine rebuild on a scooter. It contains a range of M6 bolts in different lengths, so the correct fasteners are ready when you need them for your GY6 engine. It sits alongside other GY6 scooter parts and can cut down on delays and frustration during reassembly. Rather than hunting for single replacements, you can keep this full set on hand in case any bolts are missing or worn.

Rebuild-Ready Assortment

The kit covers several M6 bolt lengths, from 12mm up to 110mm. Every size is chosen to suit GY6 engines, so you can match the original hardware closely. With a complete selection on hand, you spend less time looking for the exact length you need during the job.

Convenient Sizing

The diameter, length, and thread of each bolt correspond to the original fasteners. A correct fit helps keep the engine assembly sound and makes reassembly go more smoothly.
