Progressive Suspension 412 Series Shocks For Harley Dyna

The 412 Series shocks are simply the best value shock the Progressive offers. The 412's simple, durable design means they will be an improvement to your motorcycle's suspension performance for as long as you are riding it. The double-wall steel body construction with nitrogen charged, multi-staged velocity-sensitive valving gives you smooth, consistent damping. A five position cam-style preload adjuster lets you dial in your ride whether you're a light rider or heavy hitter. Step into suspension that works for you.

Features:

  • Nitrogen-charged
  • Cam-style preload adjuster
  • Sold as a pair
  • Made in USA

Notes:

  • Depending on model, your stock shock length is 12" to 13.3"
  • Shock lengths are measured fully extended, eyelet to eyelet on centers
  • A change in height at one end of the bike may require a change at the other
  • Changing ride height can potentially change the trail and mechanical trail
  • Heavy Duty shocks are recommended for bikes operated at or near the OEM maximum load rating over 50% of the time
  • Prior to purchasing shocks that are different than your OEM length, please verify that wheel and suspension travel can be altered without causing clearance issues to the swingarm, axle, frame, tire, fender, chain/belt and guard, and exhaust
Made in the USA

What's the difference between the standard and the Heavy Duty shocks?
Mohamed H on May 12, 2016
BEST ANSWER: Standard duty is for riders 250 pounds or less. You also need to consider if you will be riding solo because that would include the passenger. If u will exceede 250 lbs more often than not, you would need the heavy dutys. Don't buy the heavy dutys unless u need them as they are a much stiffer ride.
Are the shock covers for the top shock bolt that are offered for an additional charge a really a good choice?
A C on Sep 12, 2016
BEST ANSWER: I don't think so. The kit is nothing more than 2 bolts, 2 plastic covers and 2 zip ties. I bought it and wound up sending my covers and acorn nuts out to be powder coated. I think they actually look better without any covers, but.......
