Shocks arrived in good shape. Easy to install and improved the ride.

EMMETT on 6/14/2019

Just received the 2019 J & P catalog and these shocks are priced at $269. Why was I charged $299.?

CAREY on 6/7/2019

The Progressive 412 shocks fit my '96 Harley Dyna WG perfectly. The bike rear end in now much more lively so I feel less of the road bumps in my lower back. Excellent results. Thanks.

More confidence throughout turns, definitely a softer ride than OE. Easy installation. I like them

Rough ride but if you need bike lower it will do the job. It's a 1.5" drop specs but closer to 2".
