If your alternator is under performing or has completely died then this product is for you. OEM alternators can be expensive and we have seen used ones(not even rebuilt) for over $200. These alternators have a slightly different casing but bench tested the same as stock. To fit the Acty our kits come with custom machined spacers to make up the difference along with brand new alternator belts that probably needed replacing as well.
We have custom uprated some alternators to 100A output (56A stock) if you have the need, please contact us directly to discuss.
These DO NOT FIT trucks WITH AC but if you have AC contact us directly to discuss options.
