I installed an aftermarket universal power window kit on my truck and the passenger side window is a little slow. Is there any kind of voltage booster I can get and hook up or an large fuse to allow more power? Any help would be appreciated. Also if anyone knows a good video for installing a crush sleeve on a rear pinion lemme know. I've been looking but no video out there shows the actual process. Thanks

 

Run larger capacity power wires to it.

 

For your pinion, grab a service manual to your truck from the sticky at the top of the forum, and basically you need a dial torque wrench, and you tighten town the pinion to provide preload on the bearings via The crush washer, and you do that until you have the specified torque reading from your dial torque wrench when using it to turn the pinion.
