Factory alternators for the V35A-FTS engine are typically rated at 160 amps maximum output and produce approximately 84 amps at idle. The SBC-TV35A-320SPXi significantly increases charging system performance, delivering up to 320 amps at driving speeds and 225 amps at idle.
This results in an increase of approximately 141 amps at idle and 160 amps during normal driving conditions, providing the electrical headroom required for modern high-demand applications such as auxiliary lighting, onboard air systems, high-power audio, inverters, and other aftermarket accessories.
Part of the SBC SPX Series, this alternator is engineered for high efficiency and maximum output at low engine speeds. It features a full billet aluminum construction with both front and rear housings machined for strength, heat dissipation, and long-term durability. The unit utilizes all four OEM mounting points to ensure precise alignment and secure installation under high-load conditions.
Electrical integration is fully OEM-compatible, maintaining factory system communication and control while delivering substantially higher output.
