PKT 40mm Axle 2.0mm Offset for Lightweight Track Agility

We built this PKT 40mm axle with a 2.0mm wall thickness for less bite and easier rotation.. perfect when you want more agility instead of maximum grip.

The thinner 2.0mm wall makes this axle noticeably lighter and more flexible than the 3.2mm version. This gives you quicker turn-in, easier kart rotation, and less rear-end bite on high-grip tracks. Great for drivers who prefer a lively, responsive feel over locked-in traction.

Stick with our PKT keys.. you’ll need four PKTAK8 keys (sold separately) for a proper fit with your hubs.

Why choose the 2.0mm version:

• Lighter rotational mass for snappier direction changes
• Less rear grip / bite.. easier to rotate the kart on tight or high-grip tracks
• More responsive feel that rewards aggressive steering inputs
• Reduced weight helps with overall kart handling and acceleration

SKU: PKT40-1040-D20

Frequently Asked Questions

Q: Why choose the 2.0mm wall thickness?

A: The 2.0mm wall gives you a lighter, more flexible axle compared to the 3.2mm version. This means less bite and easier rotation, making the kart more agile and responsive on technical or high-grip sprint tracks.

Q: Do I need special hardware?

A: Yes.. you need four PKTAK8 axle keys for a secure fit. They’re sold separately and are the only keys we recommend for these 40mm PKT axles.

Q: Who is this axle best for?

A: Drivers who want a lively kart with quick turn-in and easier rotation. Ideal for high-grip tracks, classes where you need to rotate the kart quickly, or anyone who prefers agility over maximum planted grip.

Q: How does it compare to the 3.2mm axle?

A: The 2.0mm is lighter and more flexible (less stiff), so it has less rear bite and allows the kart to rotate easier. The 3.2mm is much stiffer for maximum grip and stability.
