Progressive Suspension Heavy Duty 422 Series Shocks with RAP

• Steel-bodied, monotube dampers, wrapped with a black powder-coated, progressive-rate steel coil spring

• The dampers feature a nitrogen charge that eliminates cavitation and creates a consistent ride performance with no fading

• The 422 series is a fully adjustable Softail shock, with adjustable ride height and spring pre-load

• The shocks are impressive with a show chrome quality cover that includes 4 ports for coil spring visibility

• RAP (or Remote Adjustable Preload) and it combines their high performance shocks with a remote preload adjuster

• Conveniently located behind the left passenger peg, their RAP system allows for easy turning of the shocks to account for changing loads or the addition of a passenger

this product is simply amazing the ride and handling of my Harley is superb .works beautifully with the progressive suspension fork cartridges.

I ride a 2003 FLSTF Fatboy and have been struggling with the suspension since new. First went with the Airtail which makes the bike look sick when lowered however the ride was similar to a hard-tail. Went back to stock then picked up some Works shocks which were better than stock but had no ability to adjust preload or dampening, only ride height. Contemplated buyer a new bike but the cost is just out of range, so decided to make mine a better riding bike. Since I already installed the front Monotube cartridge inserts decide to try the 422 with RAP. Yes they are expensive but it is seriously the best money I have ever spent on my 12-year old bike. Having a rear suspension that actually works is so incredibly refreshing I can't even begin to explain how satisfied I am with the ride. Just suck it up and buy these suckers, after the sting of paying for them wears off, you're gonna be a happy SOB!

The difference is night and day between OEM shocks and the Progressive RAPs. Simply the best shocks I have owned. Super easy install (make sure you have a 19mm ratchet head box wrench). Even easier adjustments.

Installed these bad boys on my 2014 FLSTN since I lowered the front end and the ride is amazing! They look great and quick adjustments are easy to do...I have gotten a lot of comments. Great product!

One of the best mods I have done. The ability to change preload for solo or two up riding and the fantastic feel of the rear suspension are great reasons to do this upgrade. Did both shocks and monotubes in my garage. Two hours apiece. Heat gun, penetrating oil and some gentle persuasion release the rear shock bolts. The front forks are a piece of cake.

Ok... was a bit skeptical that this Progressive Shock could be that good. However, bought it and figured I would let Harley install it. Well, the Harley mechanic ( a good friend) came out and said it was the best shock he had ever put on a bike He said it was easily 5 times the quality and build of the stock Harley shock. The ride... absolute difference. Small road bumps that I would tense up for before.... now, just a smooth glide. Perfect choice!
