A-NAFTULY 160A Alternator Replacement for 2007–2014 Chevy/GMC/Cadillac – 6-Groove Pulley, Direct Fit

A-NAFTULY 160A high-output alternator built to replace factory units on select 2007–2014 GM trucks and SUVs, restoring reliable 12V charging and stable electrical performance.

This direct-replacement alternator is designed for a wide range of Chevrolet, GMC and Cadillac vehicles from the 2007–2014 model years. Engineered to meet OE fitments and electrical specifications (160 Amp / 12 Volt, CW rotation, 6-groove clutch pulley), it supports vehicles that originally used part numbers such as 15093928, 15857608, 15905871 and 25877026. The unit arrives new, bench-tested, and includes a warranty and installation guidance so you can swap it into your vehicle with confidence.

Which vehicles and OE numbers does this alternator fit?

This alternator is compatible with many GM models from the late 2000s to mid-2010s. Confirm fitment against your VIN and the original alternator part number before ordering.

• Chevrolet Tahoe/Suburban 1500 and 2500 (2007–2014 ranges).
• Silverado 1500 (2007–2013) and Silverado 2500/3500 HD (2007–2014).
• GMC Yukon/Yukon XL, Sierra 1500, Avalanche, Cadillac Escalade ESV/EXT and select Hummer H2 years (see product details).
• Referenced OE numbers: 15093928, 15857608, 15905871, 25877026 and cross-references like 3342742A and AL8555X.

How does this alternator improve electrical performance?

Built with upgraded internals, the alternator focuses on consistent output and lower heat loss. Improved winding and insulation reduce electrical leaks and help the unit deliver stable amperage to accessories and the battery.

• Pure copper windings for efficient conductivity and lower resistance.
• Calibrated rotor and stator for steady 160 Amp output under load.
• External insulating coating to minimize short circuits and heat buildup.
• 6-groove clutch pulley matched to OE accessory drive systems.

Is installation straightforward, and what testing does it pass?

The alternator follows original equipment dimensions and terminal locations so it installs in the same space as the factory unit. Each assembly is subjected to no-load and load bench testing to verify electrical output and mechanical operation before shipping.

• OE-style mounting points and connector locations for direct fit.
• No-load and loaded performance checks ensure correct voltage/amperage delivery.
• Supplied with packaging and a welcome guide to aid installation.
• 18-month limited warranty and seller support for troubleshooting.

What common symptoms suggest this alternator is the right replacement?

When charging components fail, the alternator is a frequent cause. If you notice charging-system warnings or electrical problems, replacing a worn alternator with a tested, compatible unit can return normal function.

• Battery warning light on the dash during driving.
• Repeated dead batteries or difficulty starting after short drives.
• Unusual noises from the belt drive area or intermittent electrical loss.
• Voltage readings below manufacturer specs when engine is running.

Who this is for: A-NAFTULY’s 160A alternator is aimed at owners and mechanics who need a cost-effective, OE-style replacement for late‑2000s to mid‑2010s GM full-size trucks and SUVs. If your vehicle matches the listed model years and part-number cross-references, and you want a new alternator with upgraded internals, tested performance, and an included warranty, this unit is a practical swap-in solution.
