This is for a pair of Internal Bypass Coilovers. We also sell matching rear external bypasses tuned for your GX460 by professional suspension engineers. The 8112 internal bypass technology has set the bar for OEM replacement ride quality. We have personally installed about a dozen of them and the feedback has been unanimously extremely positive. There isn't another product on the market that gives you internal bypass performance with a full sized piston for maximum dampening, while also incorporating an air bump, all in 1 shock that fits perfectly in the stock location.
