Mechman high output alternators · Authorized dealer
Not every build has a model page. Engine swaps, race cars and custom bracket setups need an alternator chosen by mounting pattern, not by year and model. This collection holds the Mechman universal and racing units we list, in 170, 240 and 320 Amp. Each universal high output alternator is matched to aftermarket bracket systems that take the place of CS130 and 10/12SI style units, and the finder at the top of the page narrows the grid.
Fitment for a universal high output alternator goes by bracket, not vehicle. The units fall into two groups: replacements for CS130 and 10/12SI alternators, and replacements for CS130 alternators with a 6.15-inch pattern. Check the mounting on your current bracket against the product title before choosing. Swaps often mix parts from different vehicles, so compare bolt spacing and pulley style on the alternator you are replacing, not just the engine it came from.
When sizing a universal high output alternator, think about the whole load. 170 Amp suits a street car or swap with modest electrical load. 240 Amp covers a race car running electric fans, a fuel pump and ignition, or a street build with one large amplifier. 320 Amp is for big audio or a long list of accessories.
Mechman high output alternators in a swap or race car still need proper cable. Add Big 3 and amp wiring kits, choose a battery from our battery collection, and find plug adapters and regulators in harnesses and regulators. If your vehicle has its own page, start at all alternators instead.
