Not for my FJ Cruiser but for my Tacoma I have bought but yet install a King set-up for this reason. Heading up the James Bay Road in Quebec late this summer. It's a very long ride and I want to be able to make time on what is described as pretty bad pavement that eats Jeeps for lunch.Depending on the tire size your friend chooses he should plan on a BMC (body mount chop) to avoid tire rub. If your friend is going to invest in the remote reserves, he may want to consider upgrading the rear shock from 2" up to 2.5" matching the 2.5" coil overs up front. If he plans to drive washboard gravel roads all day with a full complement of overland gear in the back, he will be happy with the upgrade.
