hope I do not have to return items due being sent wrong parts again still waiting on refund

So far so good! Easy to order with my smartphone. My order arrived quicker than expected.

Fast and Easy

Great

4 star - very well competitive prices - 1 star due to short cut model search never loading

quick, cheap, and easy. just hope it ships fast

Nice if picture was of exact product so I know what I'm getting. Per the image online, I was lead to believe a spring was included. I received the same parts that a much cheaper kit showed, so I feel like I paid more for nothing. Plus I had to run out and pay $15 at Advance Auto Parts for the needed spring, almost doubling my costs.

great ! except i signed up for 20% discount and wasn't applied. that sucks.
