I built a custom 3 link front and rear, run some Bilstein 5125 series 14.3" travel shocks, with QA1 14" coils with 150 lb spring rate rear and 175 lb spring rate in front. Rides like a dream and will ramp 1000 on a 30 degree RTI ramp with 35" tires and 92" wheel base. The QA1 coils I run are actually coilover coils, but I run them in traditional method as a stand alone coil. They are smaller in diameter so they fit more easily on my toyota axles.
