Went in for a new battery. Staff was very helpful and efficient. They installed my new battery in an extremely short amount of time. They suggested a better product once they saw my vehicle and price was very reasonable! I would strongly recommend if in need of a battery or other services they offer.

Might be the most honest and straightforward dudes I have met in my entire life.

Big shout out to Green Bay Rebuilders for helpin out on the spot when I needed them very quick and very well done work that got my car runnin again!

Great people. Fast service.

Guys are great and very knowledgeable. Brought in a BMW alternator and they didnt just want to upsell me. I highly recommend for all your electrical rebuild-able needs.Thanks!

Very efficient, knowledgeable, and friendly. I had an alternator rebuilt here. The difference in price between oem or aftermarket and rebuilding was well worth it!

I bought a high output alternator for my suv. After installing it, my voltage at idle was low (close to 12 volts). I contacted GB Rebuilders and Royce asked me to bring the alternator in for testing, just to make sure everything was ok with the alternator and to rule out a problem with my truck. He hooked it up to his machine and ran several tests with it which only took a few minutes. He determined that everything was fine with it and suggested that a smaller pulley be used to increase rpms on the alternator (they originally put an OEM-sized pulley on it). He found a good pulley to use by crunching some basic numbers, installed the pulley for me on the alternator, and then all was well. This place was willing to work with me, showed me the tests, and didnt charge me anything for their time and the new pulley. Now my alternator is working great. Im very happy I chose this place for my alternator needs. I highly recommend them.

Competent, friendly staff who provided EXCELLENT service at a fair price!!

Great place to get starters, alternators and batteries. Most times they can rebuild your starter or alternator while you wait. Plus they have a nice collection of vintage lawnmowers in there lobby.

The guys in the shop here are awesome, very quick service. I will continue coming here .It is worth the drive from the fox valley!

Great fast and friendly service

Royce is awesome to deal with. He goes out of his way to get my customers taken care of. I will not deal with anyone else when it comes to high output alternators. These guys Rock!

Great work. Very good place to work with. Always satisfied with the work on the starters and alternators they worked on for our dairy farm.

Highly recommend! Knowlegeable, professional, and theyll repair/rebuild your alternator with even better parts if they can!

These guys know their stuff when it comes to starters and alternators

Super place for electrical rebuilt parts, great help

Royce checked out my marine alternator upon arrival, determined it was functioning, then proceeded to provide detailed assistance on possible external wiring problems to trouble shoot, then provided follow-up suggestions when initial steps failed to resolve, resulting in ultimately finding the problem. A top notch experience, I cannot recommend more strongly!

I was very impressed with the service that I received; On 6-15-2016 I went to G.B. Rebuilders at around 3:00 and brought a starter for my Ford F150. Royce took it and checked it, it didnt spin. He took the end cap off and said heres your problem, 1 brush was touching and 1 wasnt. went through my starter and rebuilt it, checked it and I was out their door at 3:30 - with a starter I know was good.

Know what they are talking about. Prices are more than fair.

OKAY ... They couldnt help with my problem BUT they helped me FIND someone who could ..

They get it fixed really fast and had a very affordable price cant beat them

Great place to have alternator and starters rebuilt, they stand behind what they do, and they sell a home made maple syrup that is better then any store bought

Great place to have your electric motors and generators rebuilt I use them for everything! Would never but aftermarket again after experiencing green bay rebuilders!

Always do it right the first time. And I always save money with my rebuilt parts.

Stop at Green Bay Rebuilders for your auto battery/alternator repair needs. HONEST and very helpful. They really do care!

Honest, helpful people here. Willing to go the extra mile to help.

Very professional staff, fast service, great prices. Dont pay double for a new starter and/or alternator, go here.

Honest prices for honest work that theyll stand behind.

They know there stuff, with fantastic rates.

Very knowledgeable and friendly staff. Will be going back for further projects.

The make things work again, that is a good thing

Very fair and fast

Most of the time they fix it right away while you wait

Good work

Royce could rebuild a starter in his sleep.

Great service

Excellent service
