The 412 Series shocks are designed specifically for Harley models and offer a simple, durable upgrade that improves suspension performance without a high price tag. A five-position cam-style spring preload adjuster makes it easy to dial in your ride for rider, passenger, or luggage loads. Made in the USA.

  • Simple, durable design for cost-effective performance gains.
  • Five-position cam-style spring preload adjuster for quick tuning.
  • Measured center-of-eyelet to center-of-eyelet for accurate fitment.
  • Multiple style options are available, including show-chrome and black covers, and chrome or black springs and end caps.
  • Some or all shocks listed are approved for road use; refer to the most recent certificate for current listings.
  • Before changing OEM lengths, confirm wheel travel and clearance for swingarm, exhaust, chain/belt guard, and tire contact.
  • When installing on '86-'15 XL models, it may be necessary to modify or space the chain/belt guard for proper clearance.
  • Slight length changes can affect head angle and steering response.
  • Heavy duty applications are recommended for bikes operated near maximum load ratings over extended periods.

Installation notes and fitment details are important—confirm compatibility before purchase and consult a qualified technician if modifying mounting or guards. 🏍️🔧
