ok so i have a 4.5 inch lift with 33s, i have bumps stops but i recently cut my fenders and have plenty of space for alot more flex.. i dont know if i should take them off or not.. and to be honest i dont really know how so if someone could tell me thanks

 

They are held on by one bolt, very easy to take off.

I would suggest testing out your current setup and see how much room you have exactly then adjusting your bumpstop from there.

 

Flex and see wut your fit is, then trim your bump stop with a bandsaw or hacksaw about a quater inch and repeat to get the best results.

 

You are measuring at full stuff and leave a little clearance for mud and debris in and on your tires.
