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 16.5”.

All early model swingarms will have the drain hole update added.

Looking to add more height in the rear?

Add the shock mount extensions to gain up to an additional 2”!

We use Geezer Engineering shock mount extensions for the perfect fit every time. They are machined pieces that include 2 mounting holes that add 1” each.

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.

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 16.5” 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.

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.

LEAD TIMES - Lead times are typically 1-3 weeks. This is from the time we receive your swingarm until we ship and update with a tracking number. Powder coat may add additional time.

The core exchange program is only available when we have stock of swingarms. If we cannot fulfil an exchange you will be notified and the order will be changed to send in first option with the core refunded.
