KTM EXC EXCF 17>23 70MM SWINGARM EXTENSION ALLOY CNC BLOCKS (TIG WELD IN)

KTM EXC/EXC-F 2017-2023 70mm Swingarm Extension CNC Alloy Blocks (TIG Weld-In)

YOU ARE JUST PURCHASING THE BLOCKS, NOT THE SWING ARM

Precision-engineered from 6061 T6 aluminum, these CNC-machined swingarm extension blocks offer superior weldability. While 7075 aluminum is stronger, 6061 provides the ideal balance of strength and ease of welding for a secure, reliable installation.

Designed to extend the swingarm by 70mm, these blocks were originally developed for KTM-based sidecars by TAG-Z Motorsports. They are also widely used by dune riders for improved stability on high-power bikes and in hill climb applications.

Compatibility:

• Fits KTM EXC & EXC-F PDS swingarms from 2017-2023 OEM Reference: 79604030044
• Will not fit linkage swing arms

Installation Requirements:

• Requires cutting the swingarm and TIG welding the extension blocks into place
• Must be installed by a skilled fabricator
• Full preheating of both the swingarm and extension blocks is essential for a proper weld

Install Service:

• Additional charges will be applied for cleaning and stripping the swing arm if not supplied clean and bare.

Disclaimer:
Installation of these blocks is at your own risk. While we have successfully installed numerous sets without failures, we cannot accept responsibility for any damage or failure of the swingarm due to poor installation.
