I used the larger wheel ### ⭐⭐⭐⭐⭐ Quick And Easy *by A***R on September 29, 2023* After 3 years of near continuous operation I bought this rebuild kit. Quick and easy with a video on YouTube for guidance. ### ⭐⭐⭐⭐⭐ It's like getting new tires on your car. *by T***L on March 15, 2019* As these drive wheels age, they wear down and leave rubber on the track which loosens its grip on the rail. The result is a gradual unnoticeable slow down and bogged down movement. Replacement is as easy as slide off - slide on, and a quick cleaning of the rail. Now the speed is up to par and working like brand new. Very cheap fix. Also consider changing the trolley wheels with the extreme duty wheels. Gualala Robotics Inc. answered all my questions and were very helpful. ## Frequently Bought Together - Light Rail Drive Wheel Replacement Kit, Robotic Grow Light Mover Part, Fits LightRail 3.5, LightRail 4.0, LightRail 4.20 - Light Rail Trolley Wheel Replacement Kit, Robotic Grow Light Mover Genuine Fits LightRail 3.5 or LightRail 4.0 --- ## 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.sa/products/7781908-light-rail-drive-wheel-replacement-kit-robotic-grow-light-mover](https://www.desertcart.com.sa/products/7781908-light-rail-drive-wheel-replacement-kit-robotic-grow-light-mover) --- *Product available on Desertcart Saudi Arabia* *Store origin: SA* *Last updated: 2026-07-22*
