We are running a set of JKS JSPEC fixed length front and rear LCAs, The fronts are 3/8 longer than stock and the rears are 1/4 (thee internet says the rears are same length, lol)
Unsure of how much increase in suspension height we gained over stock after doing a 18/59 coil swap, and adding set of JKS ACOS (set a 1 inch), and a 3/4 inch rear coil spacer in the rear (probably about 2.25 in the front and 1.5 in the rear), but the caster is 4.1 and 4.0, and the rear axle is centered. Pinion angle on both are very acceptable according to a few experts- thanks Dirtman for everything.
