The Fox 2.0 R/R - LSC shock shown is something we offered before fox had a OEM direct fit shock for the JL and JT. They took a very long time to release shocks for the JL so we made our own. Once their shocks became available, we discontinued the Fox 2.0 R/R shocks we were converting. For some reason, Fox does not offer a 2.0 R/R with LSC for the front. Not an oversight. You can also check Fox's website for all shock options:
Upgrading a Fox 2.0 to have a LSC adjuster. For most shocks, yes this is an option and pretty straight forward. However, Fox and their JL specific 2.0 R/R shock... this is not currently an option. The JL shocks have a larger hose/fittings than a standard 2.0. The fitting simply is way too large and wont work. I went and snapped some photos to visually explain it a little better:
[images below] Fox 2.0 for the FRONT of a Jeep JL is the larger of the two hoses. The smaller hose is standard size for the 2.0 shocks, which is also used the the LSC shocks.
