6061-T6 Aluminum Axle Blocks | Sur-Ron Ultra Bee, SRPNT X8 and Z27

Make rear-wheel positioning and chain adjustment easier with these CNC aluminum axle adjusting blocks. Captured stainless steel adjustment bolts allow the axle to be moved forward or backward in a controlled manner, helping you set chain tension without struggling to position the wheel by hand.

Accurate axle adjustment is important for maintaining proper chain tension and keeping the rear wheel aligned. These blocks provide a convenient way to make small, consistent changes from both sides of the swingarm.

Captured Adjustment Design

The captured bolts remain engaged with the axle blocks, allowing them to move the axle in either direction during adjustment. This makes it easier to loosen or tighten the chain while maintaining control of the rear-wheel position.

Each block is made from 6061-T6 aluminum and finished with hard anodizing for improved surface durability. Stainless steel adjustment bolts and locking nuts provide corrosion resistance in an area regularly exposed to water, mud and trail debris.
