These are used with about 7k miles. They fit gen4's but I would recommend for the regular prius, not the awd or prime. Manufacturers make a specific set for the awd and prime and while these fit, it was slightly too bouncy for me. I'm assuming that because the prime and awd models weigh about 300lbs more, it needed a stiffer spring. Swapper to Tein h.techs for my ZVW55 and have these up for sale. Price is $130 shipped to continental US. Posted via the PriusChat mobile app.
