If you’ve changed the rear suspension on your 2009+ Harley-Davidson Bagger and are over 14” shock length with an OEM swingarm, you need this!

Going over 14” rear shock length on an 09+ Bagger puts the OEM swingarm at risk of coming in contact with the transmission case. Even 14” is cutting it VERY close.

Our solution is to add a hefty relief in the bottom side of the swingarm. This allows the swingarm to clear the transmission case. This relief is fabricated in house and then welded into the swingarm as a whole. Our relief allows rear shock length up to 17”!

Standard

This is our most basic option to allow for more height on 09+ bikes. The STANDARD option adds just the relief to the bottom side of the swingarm to clear the transmission case. Additional options may be added.

Super Street Legal

If you are looking to race in the Bagger Racing League Super Street Class, this is the swingarm you need. The SUPER STREET LEGAL option includes the relief on the bottom side as well as spool mounts and spools for an easy race day setup. This swingarm is required to be legal in the Super Street Series as it requires an “OEM” swingarm assembly.

Weld on risers may be added, but may DQ you from the Super Street Series.

08- RetroFit

If you have an 08- bike that you would like to fit an 09+ swingarm onto, we now offer an option for that. The 08- RETROFIT option includes the relief on the bottom side as well as modifications to “slim” the swingarm down to fit the older chassis. Additional options may be added.

Looking to add more height in the rear?

Add the Weld On Shock Mount Risers to gain up to an additional 2”!

We use Geezer Engineering Weld On Risers for the perfect fit every time. They are machined pieces that include 2 mounting holes that add 1” each over OEM height.

Some shock brands/designs may limited to using only the top mounting hole due to design. Models with a spring perch closer to the lower shock mounting point like pictured are an example of that. If you have any questions, please reach out first.

Powder Coat

Looking to just bolt it on and go when it arrives? We offer a powder coat option to give you just that. Available in most any color.

Powder coating is an outsourced local service. Lead times may vary.

Add a chain conversion kit for the perfect set-up!

After 15” shock length, we highly recommend doing a chain conversion. The OEM belt will not be able to be adjusted properly and can be damaged or break.

WE DO NOT RECOMMEND GOING OVER 17” REAR SHOCK LENGTH!

What is “shock length”?

Shock length is the distance measured from upper to lower mounting point “eye” centers. An example would be: 13” shocks, mounted on the top mounting point of shock mount extensions would equal 15” shock length. 14” shocks mounted to the middle mounting point would also equal 15” shock length.

LEAD TIMES - Lead times are typically 1-2 weeks. This is from the time we receive your order until we ship and update with a tracking number. Powder coat may add additional time.

CORE EXCHANGE: We are no longer offering core exchanges. All swingarms are purchased outright and do not require a core exchange. RattyFab does offer to purchase used OEM swingarms for $75-$100 shipped depending on condition. Please contact us through email about purchasing cores.
