Progressive Suspension 11-1578 Fork Spring Kit

The Progressive Suspension 11-1578 Fork Spring Kit delivers superior ride quality and handling performance for your motorcycle. These original Progressive Rate Fork Springs absorb small road bumps while remaining firm enough for larger impacts, with spring rates designed to reduce front-end dive during braking while maintaining excellent ride comfort.

Key Features:

• Progressive rate design offers rising resistance to compression, allowing the spring to be soft at the start of travel for a plush ride yet firm at the end to handle big bumps
• Progressively wound design provides increased resistance to bottoming as the spring compresses
• Eliminates sag and improves stability while increasing overall ride comfort
• Improves handling while retaining OEM geometry
• Includes correct pre-load spacers for your application
• Backed by a lifetime warranty
• Made in the USA

This fork spring kit is sold as a pair and features a black finish. Designed for 43mm (1.69") fork tubes, these springs provide an ideal performance upgrade that transforms your motorcycle's front-end handling and comfort.
