  • Awesome Power!!
Had a power issue on my Jeep with a AMC 360 and DUI distributor. Upgraded to this alternator and don’t have any more problems, it makes plenty of power for the engine, lights, and accessories. Power master has never disappointed me and their alternators always work, easy to install, and last through some harsh conditions. ... show more

  • For Jeepers, you can't find a better replacement!
If this alternator doesn't last but for the warranty duration, I'd be satisfied with my purchase! By far, it's a definite upgrade from the stock OEM version. I have LEDs galore both inside and out and couldn't run certain multiple lights at the same time. That is until now! And that's not even factoring in the sound system. At idle with 3 sets of spot lights turned on this thing had a 100 amp output. That was more than the OEM put out without any lights and going down the road. They have a customer for life right here! ... show more

  • Fit 89 YJ
It was a rough install. Lots of foul language, but works like a champ.

  • Awesome
Used in a 1973 Pontiac Catalina with 6.6. Had to reclock it to line everything up but other than that it fit perfectly

  • Nice for the money
Nice piece. Black coating they use looks durable. The lower housing hole is 3/8 and the holes in my 454 heads are 7/16. I wish they oversized the hole and sleeve it so you can just punch the sleeve out if you have 7/16 threaded holes in your heads. I am going to just drill it out to 7/16 but I'm sure that voids warranty. ... show more

  • Either I have bad luck or.....
I have purchased two. The first would not charge at an idle. I thought I must have messed up my brand-new alternator since I had a battery charger on the battery while I had it running (my bad...totally forgot). I purchased another new one thinking it would not be honest if I tried to warranty it. Put the new one one...drove 15 miles to a cruise. Charging 14.2 cruising, 13.5 when cooling fans were running. Got to cruise, boom. No charge. Belt is tight, wire is intact and tight (checked for continuity too). I would not purchase again. ... show more

  • This works well on my IHC 3388
I needed more amps for lights and other options. This is a bolt in upgrade. Very happy.
