RSO Suspension Adjustable Shocks with Piggyback Reservoir provide improved suspension damping while increasing on and offroad driving comfort. They feature hand adjustable compression levels to dial in and fine tune suspension feel. These 2.5in smooth bore machined alloy bodies give maximum corrosion resistance. The 3/4in steel shafts and heat-treated steel spherical bearings offer strength and dependability. Its external reservoir allows for increased oil and nitrogen capacity giving greater heat dissipation, increasing performance, and eliminating shock fade. The piggyback design keeps the reservoir tight to the shock body away from any moving suspension components with no need for cutting or drilling. Experience for yourself the incredible performance and precise control that RSO Suspension’s new adjustable piggyback shocks deliver.
