Hey Guys, this question is actually for an H55F swapped FJ80 but I figure this group would have the most info on the H55F. We swapped the LC last year and the job included a moderate lift. Now it's back in the shop for a 3 link up front and some sliders, but we would also like to explore a potential doubler setup. The driveline length up front is relatively short with the H55F and we would like to gain some space and relieve some of the angle at the case, especially with the 3 link. Are any of you aware of a doubler that has been installed with the H55F? Thank you in advance for the replies.

NWF Blackbox would be your only option in 2026
yeah it seems as though marlin crawler has completely abandoned solid axle vehicles in favor of their new 20K ifs setup and no longer make the crawl box. @cruisermatt is right the black box is the only thing available, and you have to run an external oil pump and cooler. theres a few threads on here about doing it
