Our AXEO kits come with one oil lock piece (lower rod seat) to be used in the event you don't have an existing oil lock cup in each of your fork legs upon disassembly or in the event you remove the stock suspension and find a damper on one side and spring on the other. The damper lower rod on the cartridge will have a smaller cup and this will be evident by two different size damper bolts. The smaller of your two cups will be replaced with the larger one that comes in our kit and a new damper bolt and crush washer will need to be purchased (not included).

In order to maintain the functionality of the Harley hydraulic bump stop design, our cartridge kits require the use of an oil lock cup in each of the lower fork legs. The oil lock cup we provide is designed to match the OEM oil lock cup specifications and is provided with our kits primarily as a spare in the event you are short one cup when going to install our cartridges. 

In most stock bikes, each fork leg will already have them as they are part of the stock suspension components. The one we provide is just like the stock ones and if you remove the same suspension components from both of your fork legs then your cups will work perfectly fine. The one we provide will not be needed.
