Fork Springs & Cartridge
A Harley-Davidson’s front suspension will not function properly without fork springs and/or a cartridge kit. Deadbeat Customs carries fork springs and cartridge kits from such brands as Legend Suspension and Patriot Suspension. These brands are popular among motorcyclists because their parts meet the criteria for quality suspension items.
When you’re in the market for fork springs or cartridges, there are two things to keep in mind:
Adjustability - Cartridge kits should provide riders with a wide range of adjustability so they give riders the freedom to fix the suspension to their liking. This will make riding through hazardous road conditions much more bearable.
Compatibility - This is pretty self-explanatory, but it is a crucial factor nonetheless. It’s important to always double check fork spring’s fitment before purchasing to make sure it’s a match for your bike.
Fork springs and cartridges are important parts of a well-maintained front suspension. Deadbeat Customs offers only the best kits that will take your Harley’s performance levels to new heights.
