Last question first- We have not tested the 14.5" Super Shox. We did test the 13" Super Shox a couple of years ago, and they did not even make the review list.
Regard DK Custom Convertible Comfort Lift™ kits that can be seen at this
LINK-
We have a kit for 13" (OEM length) shocks that can be seen at this
LINK
We have a lift kit for the 14" shocks, that can be seen at this
LINK.
Convertible stands for it having two different height mounting options...primary and secondary
Comfort stands for it changing the angle of the shocks to help them absorb the smaller bumps better
Lift stands for....well that is what they have always been called, but is possibly the source of some misunderstanding.
Specs for the Convertible Comfort Lift™ made for the
13" OEM length shocks-
The Primary position gives 1.25" lift at the shocks and 1.6" lift at the end of the mufflers.
The Secondary position give almost 1" at the shocks and 1.2" lift at the end of the mufflers
Specs for the Convertible Comfort Lift™ made for the
14" length shocks-
When using the primary mounting points, it does lift the mounting point of the Trike about 1.25". (.25" from the Lift and 1" from the 1" longer shock) The primary mounting points should be used on 09-13 Trikes. They may also work on 14-16 Trikes...just depends on how far off Harley was on their tolerances.
On 2017 and up Trikes only the secondary mounting points should be used. This is because of the exhaust changes Harley made.
When using the secondary mounting points it actually LOWERS the shocks by 3/16 of an inch.
The myth that using the Convertible Comfort Lift™ raises the back of the Trike higher than the factory brackets is just that, a myth.
They actually lower the back of the Trike 3/16" compared to the factory brackets.
Why do we recommend the Convertible Comfort Lift for the 14" shocks on 2017 and up Trikes?
1. The change in the angle will give a better ride quality
2. Harley tolerances vary wildly. Sometimes you can install the 14" shocks on the stock brackets. But the majority of the time, when trying to install the 14" shocks with the factory brackets, the swingarm will come into contact with the exhaust on the right side, resulting in not being able to install the shocks properly, and/or causing the swingarm to clank against the exhaust when topping out the shocks on a larger bump.
This is why we have the secondary mounting points for the 2017 & up models (you cannot use the primary for the 2017 & up models). The secondary mounting point is 3/16 of an inch Lower than stock.
The Math:
Stock brackets with 14" shocks = 1" higher (at the shock)
Convertible Comfort Lift with 14" shocks = 13/16" higher (at the shock)
Whether the 14.5" will fit with your factory brackets or with the 14" Convertible Comfort Lift™ will depend on what year trike you have, what side of the tolerances your particular HD was manufactured at, and how much sag the 14.5" shocks have.
