I am working on my 77 fj40 restore. The cruiser will be a DD so I am to the choosing a new suspension stage. Has anyone had experience with parabolic springs? HST Parabolic Leaf Springs Only 2 leafs makes me nervous (maybe parabolics are different), but many people swear by parabolic's and their comfort. I am going to use grease able shackles and pins to help improve the comfort of the ride. Any other suggests of what you have tried and liked/disliked? Thanks for all the input!
