great price and availability

Easy order

I have not installed the prop yet. But I did get it and it was not damaged.

Wiring harness looks good so far. Have not installed it yet. Only issue an not the fault of the seller....box torn open in shipping. But everything looks to be intact.

i thought they were a bit on the pricey side but they are recommended. once i use them i will see how good they are.

Great selection and service. Thanks!

Quick easy and affordable love the website found what I was looking for and what I wanted
