I have added this article to my page as the American Jeepster Club site that used to host this seems to be defunct. If you are the author, please reach out to me so I can give proper credit to your work.

| 31″ x 10.5″ +; | A 3″ lift recommended. 2″ lift will not work for trail use due to rubbing in rear wells. | 2″ body lift can be used to gain clearance (street use only) | No trimming is recommended for most off-road use. Jeepster flares are an option. | 3.73 is ok, 4.27 is better for high-end |
| 32″ | A 3″ lift would be required, a 4″ lift would provide increased clearance without rubbing | A 2″ lift combined w/ 3″ springs or 1″ lift with 4″ springs | Trimming rear recommended. Installing Jeepster flares could replace need for lift. | 4.27 recommended |

Footnotes:
Spring lift: For any lift over 2″, the following must be modified for safety and proper performance: Shocks, drive lines, brake flex lines and steering components.
Body lift: A 2″ lift is the recommended maximum. A lift over 2″ can lead to problems with steering, shifting linkage, throttle cable, radiator hoses, gas tank filler tube and more.
A CJ 3″ body lift can be purchased and the bushings cut in half to supply the 13 required bushings of the Jeepster.
Jeepster flares are made by and available from Jim Serr (916) 645-8761. (note: This is from the original page, I don’t know if this number or flare availability are still true).
