Is this shock gas-charged?
Yes. It is nitrogen-charged to 150 PSI, which is designed to minimize air-to-oil mixing and help reduce damping performance fade and foaming.
How is the piston rod built?
It uses a 16 mm nitro-carburized piston rod to resist scuffs and corrosion, plus double-welded loops at stress areas and a 35 mm sintered iron piston.
Do I need to buy two?
Each listing is for one shock, sold individually. Replacing both front shocks as a matched pair is recommended for even, balanced ride control.
