OEM Honda Grom Chain Adjuster - (All Year)

Sloppy chain slack isn't just annoying — it's how you eat sprockets, snap chains, and chew through your ride. This is the genuine OEM Honda chain adjuster for the Grom, the exact puller block that sets your rear axle position and dials in proper chain tension every time you adjust or re-mount the wheel.

Because it's factory Honda, there's no guessing on fitment or thread pitch — it drops in and indexes exactly like the one that came off. Whether you stripped an adjuster bolt, bent a block during a chain swap, or you're just building back to spec, this keeps your slack right and your rear wheel tracking straight.
