When I ride off ledges or steps and land even into transition so not that hard of a landing, my bars slip, I have to undo the stem then straighten them and tighten it again, this happens almost every time,
Do I buy a new stem ? New bars ? Or what ?

First I would take it apart and make sure the clamping area on the bars and stem are clean, then stick it all back together and tighten it up as much as you can without threading the bolts.
If it keeps happening then you need to get a new stem.
If I could go a tenth as high as Larry Edgar goes, then I would still be blasting super high.

Ya, dont strip out the threads. Chances are the steel bolts will win against the aluminum body! Lol
But I agree.
What tool are you using to tighten the bolts?

Clean the clamping surface of your bars and stem. Often times, small metal shavings will collect in there and cause the bars to slip non stop. Then tighten your bolts in an X-pattern.
If that doesn't help, it's time for a new stem or bars. Make sure your bars aren't crushed at the clamping area.

Literally just an Allen key set ....
Like on a multitool or the individuals?
Sometimes it helps to get a bit extra torque from a tool with a handle. When I use the individual keys I tighten the stem bolts as much as I can until my hand hurts.

Could be your bars. If they're slightly crushed they'll slip easier. It's worth doing all if the above first though

Make sure that the faceplate is sitting parallel to the body; if it's not, your bars will slip very easily

Might be worth giving your bars a light sanding on the area the stem grips?
if you do this, make sure it’s a very light sanding! knurling will come off very easily if sanded vigorously.
make sure your bars aren’t crushed, and if they are, buy new bars.

Check and do all of the above first. If all fails and you feel the need to get new parts, consider the oversized stems and bars with the 25.4mm clamping diameters.

What stem and what bars do you have. Or post a picture with it taken apart.
