Easy 2005 Prius repair
Pretty easy repair. The longest part was getting to the top of strut to remove nuts. It's been almost a month since I replaced them and seem to be holding up. I would definitely recommend them. Shipping was quick as well, had mine in 2 days.
Will be using 1A Auto again.
Thanks

Great product and service.
Had 2 rear brokers springs in the back of our 2006 Toyota Prius. Order these up, shipping was quick and they worked great. Dealership quoted me 1050 to do it and I was able to do it for 150 with a couple simple hand tools.

Do they fit a 2010 Toyota prius?
The 2010 prius are 3 generation so these will probably not fit. My Prius is a 2 gen.
