Easy to install. It corrected the 4 wheel drive problem ### ⭐ Junk *by S***N on October 21, 2023* Product worked fine on the bench when connected to a 12v 700a battery but was extremely difficult to stroke by hand. Once I got it on my truck it failed to stroke when it would receive an electrical signal and again I could barely move it by hand. I’m assuming the spring is far too strong for the power in the circuit. Called tech support and they were worthless just said to return it. I cleaned up the old oem one and it worked like a charm. ## Frequently Bought Together - Dorman 600-399 Front Differential Lock Actuator Compatible with Select Dodge / Ram Models - Slippery Pete 5cc Hand Pump Transfers Gear Oil, Transmission and Differential Fluids From Quart Bottles (Not for Red Line Quarts) (1) - Valvoline Advanced Full Synthetic 75W-140 Gear Oil 1 QT --- ## 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.com.br/products/71095374-dorman-600-399-front-differential-lock-actuator-compatible-with-select](https://www.desertcart.com.br/products/71095374-dorman-600-399-front-differential-lock-actuator-compatible-with-select) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-06-06*
