I put Old Man Emu # 910 coils on mine.
Gen 2 coils , in retrospect are probably of higher quality and cheaper and and locally available. Like $50/ pair.
I put Rancho RS 5000 shocks on the rear. They arn't gas shocks and snub real good right now . I'm able to go up and down 41 without "white knuckles" now.
KYB are a far better shock and that's what I reccomend.
