Product Description
L-BODY NIPPONDENSO 90AMP ALTERNATOR, BRACKET & HARNESS UPDATE
For All L-body cars 84-87
Do your headlights dim when you get on full boost? Wipers run slow if you have on the heater? Do you have a sub in the hatch with a big amp and the car exhibits noticeable loss in power when the tunes are on?
Low power electrical issues are caused by the under size, anemic power and amp delivery capabilities of the old school truck alternator from the 70s that was originally put on the 84-87 L-body cars. It just can not keep up with a car with a power module, logic module and 4 power hungry fuel injectors!
FIX THESE PROBLEMS FOREVER with this completely plug-n-play and ready to install turbo L-body Nippon Denso 90Amp upgrade.
This set includes the easy adjust 1 piece alternator bracket, a NEW NipponDenso/ACDelco 90amp alternator with serpentine belt pulley and the NipponDenso style charge harness completely ready to go. Just remove your old Cryco truck alternator, harness and bracket and plug in the harness, mount the alternator and add your serpentine belt. Done. No other wiring, splicing, cutting, drilling, nothing, plug-n-play.
INCLUDED:
- Easy Adjust 1 piece alternator tensioner bracket
- Complete front engine charge harness, ready to go, all connectors, freshly re-wrapped, hi-temp convoluted cover, L-body specific turbo connectors.
- NEW NipponDenso/ACDelco 90amp alternator with standard serpentine belt pulley
This is everything you need to upgrade your L-body car with the crappy 3 piece adjuster and behemoth Cryco truck alternator that cant keep up with a fuel injected cars power demands. Add this setup and you will enjoy the following verified benefits:
- You can actually adjust the alternator belt tension easily, you can actually see the adjuster nut, and the adjustment can be done in seconds with only a 13mm socket
- Your headlights will not dim under full boost
- You can run all your accessories and the radio at the same time and still use the wipers
- You will have extra room for service of the oil filter because the NipponDenso alternator is 20% smaller than the Cryco and Bosch alternators
- You can also upgrade to a 120amp Nippon Denso if you want or need to (big honking stereo amps for example)
This is a true bolt on factory parts application. Be aware that you are getting the needed 1 piece alternator bracket, the new NIppon Denso alternator with the correct surpentine pulley already installed and a complete turbo front charge harness for the new alternator.
This upgrade has been performed by many many people, all my cars have the upgrade and it makes a HUGE difference not only in the general capability of using any or all accessories at the same time but also in how the car runs under full boost. Before I discovered how to do this the first time my 87 GLHS had all the problems mentioned above, now it has none of them. So my 86 GLHS has the upgrade and I also did it to my 85 SC. What a difference!

shocking
I have been dealing with my factory alternator for a decade. This upgrade eliminated my spark blow out and system voltage drop when the cooling fan kicks on. This kit comes with a new AC Delco replacement.
