usable but needs a bit more

Summit RacingSummit Racing Verified Purchase

Beware, comes with a horridly cast, non painted alternator that's extremely cheaply made. Brackets and pulley's are perfect, but the accessories leave alot to be desired. The instructions are the worst Ive ever seen and hardware labeling are terrible. Its basically just a giant bag of bolts and washers you need to sort through an improvise on. (the instructions never say when to use washers or which diameters to use..so you basically need to guess. Once you get past that it isn't too bad of an install. They also skip half of the things you need to do and have you installing belts before putting pulleys on. Expected a lot more from March. ...read more

Looks like March performance just threw a few damaged boxes in a big box and ship it. Water pump was not black like in picture was cast and very rough looking cast, damaged pulley on Ac and was rusting, shouldn't have been rusting, says to be aluminum. You could tell it was packaged damaged because the box was in good shape. The pulleys and brackets look good nice powder job. Haven't put it on yet waiting pulley summits trying to take care of it. Over all view kind of over priced.. ...read more

A great product, but.....

Summit RacingSummit Racing Verified Purchase

This is a great product if you have no engine accessories for your build. Alternator, pulleys, PS pump are black powder coated; water pump is a standard iron pump, not painted, A/C compressor is natural. Includes all bolts and brackets. BUT neither of the two required serpentine belts are included in the kit. What's up with that, March?? Plan on buying the 2 belts from the "suggested" accessories list. 4 outta 5 stars for failing to include the belts. ...read more

Bolted right up just like it is supposed and took all the guess work out on trying to configure brackets and parts. A+++++ Just wish they would stated what size belts are required so I could order them at the same time. Was able to pick up a 59 inch belt locally but had to order the short 39 inch belt off the next because nobody stocks them that short. ...read more
