Product Details

Progressive Suspension Heavy Duty Fork Springs For Harley Big Twin

The heavy-duty progressive-rate fork springs soak up small road bumps, yet are firm enough to absorb the ones that shake the kidneys. Spring rates have been chosen to reduce front end dive during braking, yet still provide excellent ride comfort, and also balance the weight of a bike laden with greater-than-average loads. A progressive-rate spring has the advantage of a resistance to compression that rises as the spring is being compressed - it gets tougher to compress as it is compressed. The benefit of this is that the spring can be soft enough at the start of the travel to offer a plush ride, yet be firm enough at the end of the travel to soak up the big bumps.

Features:

  • Progressive spring rate
  • High-quality chrome-silicon wire
  • Precision wound
  • Made in USA

Note: Spacers are not included. Heavy Duty shocks are only recommended for bikes operated at or near the OEM maximum load rating over 50% of the time.

Fitment Notes & Exceptions
  • Changing ride height can potentially change many carefully-engineered attributes of your bike, including trail and mechanical trail
  • A change in ride height at one end of the vehicle usually will require a change at the other end
  • Heavy Duty shocks are recommended for bikes operated at or near the OEM maximum load rating over 50% of the time
  • Prior to purchasing springs that are different than your OEM length, please verify that wheel and suspension travel can be altered without causing clearance issues - common interference spots include triple trees, fenders, frame, and of course, the ground.
  • Not for use with Trike models (FLHTCUTG, FLHXXX)

Nice springs .....but!
These are being installed on a 08 ultra Classic that is getting a sidecar installed. The spring wire was substantially larger in diameter than the stock springs and progressively wound. Installation was fairly straight forward with one exception. The spacer they include is undersized in diameter to the spring. The spacer is 1.056 od and the spring is 1.260 od. I called and was informed it was just schedule 40 pvc pipe. There is a washer that goes between the spring and the pvc spacer, to distribute the load evenly, but that does nothing to help the distribution of the load under the fork cap and the fact it has a ID .944 .with a wall thickness of just .200 that left just .116 area for the load. With the spacers ability to slide back and forth in the fork bore , I felt better making something that fit a little better. I used schedule 40 gray electrical pvc 1"ID , which has a 1.325 OD and reduced it to 1.265. By doing that it fit the bore better an transferred the load more uniformly.

Is this a lowering fork kit?
A shopper on Apr 12, 2017
BEST ANSWER: No but im sure if you cut a piece of the filler pipe it will lower the bike a bit. There is another kit thats specific for lowering.
