2011 Toyota Camry Alternator Upgrade — 2.5L Four-Cylinder
The 2010-2011 Toyota Camry 2.5L leaves the factory with roughly 100-130 amps of alternator output. Factory electrical load on this generation already runs 80-110 amps once you account for climate control, lighting and accessories, which leaves very little headroom for anything you add. This direct-fit JS Alternators unit drops 250 amps into the stock location using the factory mounting and the factory plug.

Why the stock Camry alternator runs out of room
A 500-watt RMS audio system pulls roughly 50 amps on top of the vehicle's existing load. On a 100-130 amp alternator that puts the charging system at or past capacity any time the bass hits, which is where headlight dimming and voltage sag come from. It is a supply problem, not a wiring problem. Background reading: our Toyota Camry alternator guide and the alternator sizing guide.
Fitment:
This is a direct fit high-output alternator for the 2010-2011 Toyota Camry 2.5L. Being a direct fit, this alternator fits directly into your stock alternator location.
Plug:
This high-output alternator comes with a factory style plug so that your OEM plug will plug directly into the alternator. Therefore, with an OEM style regulator, it will have a factory voltage set point.
NOTE: If you require charging at a certain voltage setpoint, we offer a selection of different voltage regulators that you will need to purchase with the alternator for it to be installed. Individual regulator options (verify compatibility and charging voltage): 14.8V Internal (Pigtail) | 14.8V Self-Excite | 15.5V Lithium | 16V Lithium | GM 1-Wire
Pulley:
This alternator also comes with a stock size pulley in which the stock belt is used.
Big 3 Wiring:
When upgrading to a high-output alternator, it is required to upgrade your wiring with the Big 3 Wiring Upgrade Kit (choose a cable length: 4ft 1/0 positive cable kit / 6ft 1/0 positive cable kit / 10.5ft 1/0 positive cable kit / 20ft 2/0 positive cable kit). It is recommended to use 1/0 100% copper wires for the upgrade.
