All-Metal, No More Flex-Tracs. Modern Power Window Upgrade Conversion Kit for Full-Size Jeeps (63–91)
Better materials, stronger performance, easier installation: the upgrade your Jeep should have had from the factory
Time for an Upgrade: Get Your Jeep Windows Out of the Stone Age!
If you've got a Jeep with manual crank windows or an old, failing power system, this all-metal construction conversion kit is your definitive solution. The original power system relied on plastic flex tracks that were always breaking, and even replacement tracks don't last long. Engineered and proudly developed right here in Texas, USA, this system replaces unreliable OEM parts with superior materials for reliable, long-lasting performance.
This kit works on full-size Jeep Wagoneers, J Trucks, and Cherokees from '63 through '91. Unlike universal kits that require cutting, drilling, or shimming, our system is designed for a clean, plug-and-play install right out of the box. When you choose this genuine Vigilante part, you invest in durability and quality proven in our own builds.

See Nick from JeepHeritage detail this all-metal conversion kit, showing how our custom engineering ensures a plug-and-play installation without modification or guesswork.
The JeepHeritage All-Metal, Modern Power Window Conversion Kit is the definitive solution for upgrading the window system in your classic Full-Size Jeep, covering Wagoneer, Grand Wagoneer, J Trucks, and Cherokees manufactured from 1963 through 1991. If your existing power windows suffer from the unreliable, constantly breaking plastic flex tracks, or if you are looking to convert your manual crank system to electric while maintaining the original crank appearance, this system is custom engineered bracketry designed specifically for you.
Developed in Texas, USA, this kit eliminates the need for complicated installations involving cutting, drilling, or shimming that characterize universal switches. Our solution bolts right in, offering a reliable, simple, and high-quality upgrade. The installation is completely plug-and-play, guaranteeing no DIY guesswork.
We have meticulously solved common fitment issues. Our switch assembly includes two spacers set at the precise 7° angle required to ensure your crank sits perfectly perpendicular to the door panel. Furthermore, the unique two set-screw mechanism allows you to adjust the shaft length precisely, accommodating different crank styles (metal or rubber knob) for a flawless fit.
Included in the kit for pre-existing power window upgrades is our custom-designed lifter bar, cut from solid 1/8 inch thick stainless steel. This superior design prevents the common problem of interference and hitting the rain wipe, a known issue with vendor alternatives. For four-door kits, a stainless steel stiffener bracket is provided to secure the rear motor during door operation. Since nothing in this kit is made of raw steel, you are guaranteed a rust-free, durable installation. This is the power window upgrade your Jeep should have had from the factory.
Upgrade your classic Jeep with the same power window system used in Vigilante restorations — engineered for strength, reliability, and an OEM-quality fit with no drilling or modifications required.
This is the ultimate bolt-on power window conversion kit, designed specifically for Jeep Wagoneer, Grand Wagoneer, Cherokee SJ, and J-Truck models. It eliminates the guesswork and poor fitment common with universal kits, delivering a clean, factory-style installation.
Originally developed out of frustration with unreliable aftermarket solutions, our reengineered system is built to last. Each kit starts with high-quality NuRelic components, then enhanced with Jeep-specific upgrades designed and fabricated in-house.
