High Output 250 Amp Alternator 14-18 GM Silverado Tahoe Suburban Escalade Sierra

Most Alternators Are Custom Built To Order. Standard Build Time Is 2-3 Weeks. If You Need An Alternator Sooner Than That, Please Contact A Sales Associate To See If Any In-Stock Options Are Available.

NEW! - The cast housing Elite series alternator offers the highest possible amperage and durability available in a large case alternator. 6 phase technology combined with massive twin rectifier assemblies and 12 diodes makes these alternators totally durable for daily use, while still maintaining great output: 180 amps at engine idle speeds and a full 250 at cruising speeds. This unit comes with an OEM diameter pulley, making it perfect for high RPM and racing use and uses stock belt length.
