GAZ is a range of premium gas-filled performance shocks. They feature a range of 40-point external knob adjustment, so easy and precise fine tuning can be achieved without removal. Gold hard-anodized exterior finish. Gaz is so confident in their quality that every shock comes with its dyno test sheet. Sold each, but should be fitted in axle sets. Lowered shocks are for cars lowered 2" or more from standard.
