Our take on the Wilson HD 8 LHA Series Alternator 12 V 90 Amp

The Wilson 90-05-9122 is a remanufactured 12 V, 90 amp alternator for heavy-duty trucks, built on the 8LHA family with a J180 mount and external fan. It is a direct replacement for a worn or failed original unit rather than an upgrade, so output stays at the stock 90 amps. Buyers get a rebuilt alternator at a lower cost than new, but remanufactured units vary in how long they last, and the J180 mount and external fan limit it to trucks that use that setup.

Questions and answers

Is this a new or remanufactured alternator?
It is remanufactured. Wilson rebuilds a core unit to the 8LHA design, which is why it costs less than a new alternator.
Will it fit my truck?
Fitment is listed as universal, but the J180 mount, external fan and 8LHA family mean it only bolts up to trucks built for that setup. Check your original alternator's mount and family before buying.
How much power does it make?
90 amps at 12 V. That matches a stock truck charging system but leaves little headroom for large added electrical loads.
Does it spin the same way as my old one?
Yes, it rotates clockwise and is negative ground, the common configuration on trucks that use the 8LHA.
What is in the box?
The alternator itself. Mounting hardware and belts are not included, so reuse or replace your existing parts.
Where is the Wilson HD 8 LHA Series Alternator 12 V 90 Amp cheapest?
At Walmart, for $337.09, as of our latest check.
