2-1/2 inches would give me the clearance needed to get my unit in and out of the driveway without the use of ramps. Curtis was able to use the lift kit directly because he has a side mount axle but in my case I have a top mount which means a side mount kit has to be welded to the frame. Below is info I received from Jayco and Dexter about the conversion and possible warranty concerns since my X17Z is virtually new. Hope this help others needing a slight lift.
Email from Jayco about affects on warranty and stating that X17Z models use a top mount ….
Good morning, and thank you for contacting Jayco.
Because Jayco has not factory tested this after market installation, we do not contain the supportive information needed to make proper recommendations. This being said, if you decide to make this after market modification, it will not void your warranty entirely. We can still consider your unit under warranty until your warranty expiration date, but we cannot cover any damages that may occur during the installation process of this kit. We also cannot cover any future items that may become damaged from this installation. For this specific model, the axles have always been installed with the top mount process. If you do not feel comfortable having the kit installed on your unit, it may be best to contact Dexter about possible axle upgrades. I hope this information is useful.
Email from Jayco talking about the factory lift kit option……..
The units with the 2 inch lift on them, they do contain different axles. If I am correct, I believe they would be part number 0259548. To confirm this information, it is to contact our parts department, a Jayco dealer, or Dexter. Even if you just contacted Dexter, they will know the best suggestion for your unit.
Email from Dexter talking about parts needed to lift my axle,,,,,,
Good afternoon Mr. Gage,
In the last file attachment, please find the full description for the axle for Dexter SN 121930905 that you stated that you had. Your axle is currently being used in a top mount application, meaning that the axle is mounted underneath your trailer frame. In order to use our lift kit, part number K71-707-01 for a single axle trailer, YOU MUST INSTALL OUR TORFLEX SIDE MOUNT HANGER KIT, PART NUMBER AP-166. YOU WILL THEN BE ABLE TO INSTALL OUR LIFT KIT BUT YOU MUST USE OUR LIFT KIT WITH OUR AP-166 SIDE MOUNT HANGER KIT.
