I needed it immediately to head out on a hunting trip the next evening so I had it shipped UPS Next Day. UPS dropped the ball with shipping and Luke called me first thing in the morning to let me know that it looked like it wouldn't be delivered that day and that he had already filed a claim with UPS. I returned from my trip to find the alternator at my house. It was well packaged, fit perfectly and immediately cleared up my charging issues. Luke refunded the shipping charges for me since the alternator did not show up as scheduled. Thank you Luke and your team for the excellent customer service. You're on the short list of companies I'll recommend without hesitation!

Love the customer service here

This is such a great place! Wounderful helpful people!

I have used HEI to check or rebuild all my generator's, alternator's and starters for 50 years! Trucks, cars, tractors, RV's or my snake river boat HEI... read more checks them all! Until recently that was all I used them for. Then Larry introduced me to an oil product called IXL. I was a lube tech in industry with mechanical apprentice and have been to many continuation ed. classes on oil. I'm very aware of the so called "Miracle Products" available that fix everything. I remember thinking, "whatever" when Larry asked me to try the oil and give a review if I liked it. I have a Pacific Energy fireplace insert and the blower motor quit working. It "wouldn't turn" and of course when I tried to order a new electric motor I was told it was no longer available so I vacuumed all the lint and dust out of the windings. That's when I noticed oil ports to the bushings. I put a drop of IXL in each bushing port and slowly began by force turning the fan/motor housing for a few minutes then added another drop of oil. After 30 minutes of slow turning by hand it began to loosen and turn freely. I reinstalled the blower, started a fire and waited for the heat sensor to heat up and turn on the fan. It's been run for a week now and even running quieter. IXL is going in the next oil change on the 2003 Ford 7.3 diesel. The 7.3's have an injector issue called "Stickion". I like what IXL does for a frozen electric motor! Lets see what it will do for my ol ford! Honesty, Integrity, Sound Advice and Great Service is what you get everyday at Hagemeister's! Thank you, Larry, Helen and Luke!
