Garage door adjustment

[binare]

Finally have a garage but the door stops about 3 inches below the top of the opening so I can't fit the Jeep in. There is plenty of room left on the rails and enough slack in the steel cable if I set the sensor back. Is there any reason why it would be set like that I'm missing? Anything I should look for when I set it back farther? The way it is now the last set of wheels don't make it past the 90 in the track, does it matter if the whole door goes horizontal?

Prob sounds retarded but I've fugged with a garage door before, seems simple enough but incredibly welfare and easy to rip apart so figured I'd ask.

Should be a stop adjustment on the electric garage door opener. Do not attempt to adjust the giant spring mounted on the door header. it can kill you.

Ya I know Andy, I'm just asking if it was possibly set like that for a reason that I'm missing.

You don't usually want the last roller to go past the 90 as then the door is completely horizontal and all the weight comes off the cables. Options are to have the tracks at perfectly horizontal but angle up at the back so the door always sits on an angle or raise the whole track up(and spring) so that the 90 is closer to the ceiling.  Neither are easy and both complicate the use of a door opener.

Perfect, thanks for the info, exactly what I looking for, guess ill be raising it.

That will mostly likely require unwinding the springs and mounting them higher as well. Not rocket science, but some common sense and long bars(not screwdrivers) are required. And some more track, longer cables.....

You just need to drive faster then Will fit the second time for sure!

Do you drive in and out of this garage every day or is it more of a shop? One option could be to pull the cable thats closer to the top of the door to disconnect the chain, then you can manually push the door up higher than the garage door header to drive in. Of course that would be a pain if you had to do it everyday though...

Just air down...
