best O/R shackles
Check out JeepCJ5 "DAYSTAR – SUPER SHACKLES" greaseable by daystar products =1/2" lift and up. I think the thread by Army Green used them. I see "4 wheel parts" sells them.
Daystar KJ61001BK 0.5" Lift Greaseable Shackle
Daystar makes .5", 1.5" and 2.25" shackle lifts that should work.
The shackle itself is 1" longer than stock but because it is connected on one side of the suspension it gives half the lift as what was put on.
So for a .5" lift it is a shackle that is 1" taller than stock.
The 1.5" lift is 3" longer shackle than stock.
And the 2.25" is 4.5" longer.
