I hear Dostech & Napa (cheapest line they have) work VERY well. The truck is so light, it doesn't need (and actually benefits from the lack of) fancy valving. Depending on how high that SPOA of yours is... I hear F150 shocks work rather well.
The 'best' way to get a good matching shock is to measure your suspension travel & distance from shock mounts. NAPA has a book that they can use to match your measurements, and get you the proper shock.
