Functional and Effective Door Window Lifts for Every Occasion

If your truck features power windows alongside manual window rolling capabilities, you may know that when they start to diminish in function, the main component that will likely need replacing will be door window lifts. 

What are door window lifts?

Window lifts are the internal components that allow you to automatically wind your door windows up and down, typically via the central control console or buttons set within the driver’s door. Door window lifts can also be connected to the central locking mechanism to ensure that windows aren’t accidentally left open once the truck is locked, which can minimize the risk of theft or even unwanted debris or water from getting into your vehicle.

Many have an in-built safety feature that will cause windows to automatically wind down should they meet resistance (such as an arm or a finger, or even paws if you take your dog on road trips with you) to minimize the risk of accident or injury. This is often only available on driver-side windows, however.

If you experience a loss of function, it can be worthwhile to define how your powerlifting operates to get the right window lift replacement parts for your needs. Here at Big Rig World, we stock electric window lifters, regulators, assembly kits, power regulators, motors, handles, springs, regulator kits, airlift cylinders, glass lift channels and more from a host of reputable brands.

What to consider when replacing door window lifts

As door window lifts are an integral component of a functional window system, it can be a good idea to replace these as soon as you notice an issue. This isn’t likely to be as simple as a handle change for example, so why not contact one of our expert engineers for advice? You can reach us by chat, email, or on the phone and we will be happy to answer your queries, or source parts if you can’t find them on our website.
