RE: LST questions...
factory servo savers are great, just add 1 or 2 on each of them(depending how tight you want your steering).
i have been running the same savers with 2 extra springs on each for a LOT of gallons, in fact they were on my aftershock that i converted to a LST2 2 years ago.
i got this aftershock used, so it has even more gallons on it ! and no slop in the savers.
