Anyone know why there are two kits for the '99 - current F53 front suspension? '99-'05 and '06-current? Two different prices shown too.
I know the suspension changed in '04, so that could explain some difference, but $300 and that doesn't match the year they show?
And no difference for 16K (6500 pound front axle) to 26k (9000 pound front axle) units? Same replacement "softer" leaf spring and airbag for all? Maybe they just don't show the specifics on the website?
And (another "and", sorry) they mention the kits being a "generation II air ride". Have they changed their system over time? Was there a generation I?
