Leatherneck KM200 Universal Adjustable Seat Strut - 9.5" Max Height Zinc Plated - Sprint & Oval Racing

Dialing in your chassis setup requires the right go kart parts, and the Leatherneck KM200 Universal Adjustable Seat Strut delivers the precise rigidity needed to transfer weight effectively through the corners. When you're tuning your kart's center of gravity, seat placement is just as critical as your engine and motor alignment. This zinc-plated strut allows you to fine-tune your seat height and angle, reaching a maximum of 9.5 inches, with the flexibility to cut the insert for shorter applications. Whether you are running junior classes or full-size sprints, maintaining a rigid seat foundation prevents chassis bind and ensures your tires are doing the work.

Optimizing Chassis Flex and Handling

A rigid seat strut isn't just a mounting bracket; it's a critical tuning component that dictates how your chassis flexes under load. By securing your seat firmly to the 1.125" or 1.25" frame rails, the Leatherneck KM200 strut ensures that energy transfers efficiently from the driver to the track. When you are pushing the limits, you don't want a sloppy seat setup compromising your exit speed. This level of adjustability complements other tuning variables, from your go kart sprockets to your tire pressures, allowing you to adapt to changing track conditions on the fly.

Durable Construction for Relentless Racing

Track debris, vibration, and constant adjustments demand hardware that won't quit. The zinc-plated finish on this strut provides superior corrosion resistance, ensuring it survives wet races and aggressive pit-side wrenching. Just like you wouldn't compromise on your wheels parts, you shouldn't compromise on your seat supports. The single pinch bolt design simplifies length adjustments, while the standard four-bolt base clamps securely to your frame, minimizing the tools needed during high-pressure setups.

Technical Specifications

• Zinc Plated Finish: Provides maximum corrosion resistance against track elements and harsh weather conditions.
• 9.5-Inch Maximum Reach: Offers extensive length for taller drivers or specific high-mount seat configurations.
• Customizable Length: The strut insert can be easily cut down to accommodate shorter seat heights and junior chassis.
• Universal Rail Fitment: Clamps securely to both 1.125" (30mm) and 1.25" (32mm) frame rails without slipping.
• Single Lower Pinch Bolt: Streamlines pit adjustments, allowing for rapid length changes between practice sessions.
• Four-Bolt Bottom Clamp: Distributes clamping force evenly across the rail to prevent chassis crimping and maintain rigidity.
• Heavy-Wall Tubing: Resists bending under high lateral G-forces, keeping your seat exactly where you mounted it.

Frequently Asked Questions

Q: How do I determine if the KM200 strut will fit my kart frame?

A: The KM200 is designed with a universal four-bolt base clamp that is fully compatible with both 1.125" (30mm) and 1.25" (32mm) standard kart frame rails.

Q: Can I shorten the strut if it is too long for my seat position?

A: Yes. The strut insert is designed to be customizable. You can easily cut the insert down to your desired length to accommodate junior chassis or lower seat mounting configurations.

Q: How does the single pinch bolt design help with trackside adjustments?

A: The single pinch bolt allows for rapid length adjustments without needing to remove the entire strut from the frame. This makes it much faster to fine-tune your seat angle or height between practice sessions.

Q: Does the zinc-plated finish require special maintenance?

A: The zinc plating is applied specifically for corrosion resistance against track debris and moisture. While it is highly durable, we recommend wiping it down after wet races to maintain the finish and ensure the pinch bolt threads remain free of grit.

Q: How many struts should I use per seat?

A: While setup varies by chassis manufacturer and class, most racers use multiple struts to ensure even weight distribution and to prevent chassis bind. Always check your chassis manual for specific mounting point recommendations.
