Evan-Fischer Transfer Case Motor – Fits Chevy, GMC, Ram, Yukon, Suburban, Silverado, Avalanche 2004-2010 (NVG246)

If your 4WD isn't engaging, the transfer case motor might be the culprit.

This Evan-Fischer unit is a direct replacement for a ton of trucks and SUVs from the mid-2000s.

We're talking Chevy Silverados and Tahoes, GMC Sierras, Yukons, Suburbans, Avalanches, and even Dodge Rams and Cadillac Escalades, mostly with the NVG246 transfer case.

It comes with a 1-year warranty, and the seller offers a 30-day return policy.

Just make sure your truck has the RPO code NP8 (the push-button shift).
