2 bad alternators!
I bought the first alternator & in a matter of weeks it was done for, so they sent a replacement (refurbished, as a favor to me) & within a matter of days it went. Had both alternators tested & yes they were faulty, nothing wrong with installation. I've tried repeatedly to contact them with no avail, & if your reading this review a paid good money! You would think they would stand behind their product & customers!
Desired outcome: NEW replacement alternator not a refurbished!
Quick Delivery and Solid Products, but Bracket Issue with Sinister Diesel Kit
Got my stuff from Sinister Diesel and it came in pretty quick. Only thing that kinda sucked was the bracket for the kit was all wrong. But hey, it's all good, I just had to rig it up a bit to make it work. Other than that, everything was solid and worked like a charm. Definitely gonna keep coming back to these guys for my diesel needs.
Impressed with Sinister Diesel's Quality and Timely Delivery!
Got my order from Sinister Diesel and I gotta say, I'm pretty stoked about it. Haven't had a chance to put the parts in yet, but they look like they're made of some solid stuff. And the best part? I managed to get it all in before the April 30th deadline. Score!
