Here’s my 1990 Jeep Comanche, bought it stock about 3 years ago, 2.5l with a 2wd AX4. The after pic is how it sits now, specs on build:
9.5” Rusty’s spring with 2” puck, roughly country long arm crossmember with custom made long arms out of 1.5x.250 DOM, rear is a Rusty’s 4” lift spring over axle. It also has rough country track bar drop down bracket and an adjustable track bar with a custom OTA track bar bracket. Rear shock tabs were re welded higher on the axle for clearance. Rear axle is an 8.25 out of a 96, front is a D30 out of an 86 I believe, regreared to 4.88, trans is a 4x4 AX5 out of an 86 Cherokee
