ditch them if you dont want to spend any further cash on them , stupidly poor turning radius, SPV damping which still confuses me (why put a platform in their downhill forks?) generally poor reliability the only thing you could do it speak to TF tuned and see if they have any TPC+ internals now that would produce a very different fork

i used to have a pair of 04 sliders. felt great when they worked, but they required a lot of maintanence. TPC actually works really well and is a very under rated damping system. but manitou insist on putting spv, spv evolve,intrinsic bull crap etc etc crap in all their forks. If they had just stuck to tpc they would be doing much better. imo sell them, they are not worth it.
