GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE). Review: Installing a transfer case actuator motor on a Silverado is not a whole lot of fun to be sure. Although the old actuator insulator can be re-used - sometimes - I don't suggest it. Having learned the hard way that using an old one can be more trouble than it's worth especially when it's covered in dried-out RTV, I ordered a new one from these folks. I'm glad I did! Shipped quickly and very well - almost too well - packaged, the insulator was a perfect fit. Would highly recommend this Seller.

I'm actually just writing this review to say that this can be easily made to fit the earlier pre 2003 246 transfer cases. The correct early style plate was discontinued. This plate is identical to the pre 2003 version except for one side. They changed the shape to match an update to the case. It's just a cosmetic adjustment to get this to fit the older cases. Use the old part as a template (line up the holes) mark with a marker and cut it with a pair of wire snips. Once it's roughed out sand it smooth on a belt sander or with a rotary tool (this is optional if you don't care about how the finished edge looks). See the photos for details. ## Frequently Bought Together - GM Parts 12384973 Transfer Case Four Wheel Drive Actuator Insulator - Dorman 600-910 Transfer Case Motor Compatible with Select Models - ACDelco GM Original Equipment 88962315 Transfer Case Range Select Position Sensor --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/411138785-gm-parts-12384973-transfer-case-four-wheel-drive-actuator-insulator](https://www.desertcart.tn/products/411138785-gm-parts-12384973-transfer-case-four-wheel-drive-actuator-insulator) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-10-18*
