Bestop's upper door sliders utilize a front to back sliding window, a significant advantage over the original zipper system. For use with YJ Wranglers with factory steel half doors. Note: only rear section of window slides, front is fixed glass. Only fits factory steel half doors on factory soft tops.
As close to full hard doors as you can get with half doors. Worth it.
LOVE these sliders. Made my jeep much quieter and much greater eye appeal than the soft uppers. Super easy to install, just open box, slide in the holes and good to go. Very happy with this purchase and you had the best price and I searched everywhere.
the upper sliders fit well and seem to be sturdy, the windows slide a little tight, I'm hoping they loosen up a little after more use
Overall these are great upper doors for spring and fall or all year. They look,fit,and function very well. I wish the rear window was a little bigger. Hard to get your arm out.
Q: Will these uppers fit with a hardtop? Answer this question
A: We typically don't recommend using soft doors with Hardtops considering the need for necessary adjustments to make them fit correctly, that and making sure there is the expectation understanding that soft doors do not preform like hard doors do, especially when a Hardtop is on.
