I chose Bilstein HDs (pictured to the right) from ShockWarehouse.com. I have read great reviews of these shocks, which are developed to provide better stability and bump rebound control. With the improved performance combined with the club discount from TrailVoy.com, they are a no-brainer addition. Since the front strut is already all apart when doing a spacer lift, it’s highly advised to replace the front shocks at the same time.
For rear shocks, it seems the simple choice are BDS shocks. They have two options for the 360 platform, gas-charged shocks, and hydraulic shocks. I went with the 55-series hydraulic shocks, however will switch to gas-charged once the 55s die.
