Frequently Asked Questions
What does this cartridge kit replace?
All OEM fork internals — the dampers and springs inside the fork tubes. The fork tubes themselves are reused.
Do I get both stock and lowered springs?
You choose stock or lowered height at purchase. The kit ships with one set tuned for your selected height.
Will this reduce front-brake dive?
Yes — the progressive damping and spring rates are tuned to resist front-end squat under hard braking.
Is installation a DIY job?
Most riders have a shop install this due to fork disassembly, spring preload tools, and bleed procedures. Professional installation is recommended.
What's the warranty?
Progressive includes a Lifetime Limited Warranty on materials and workmanship.
