On my other brand buggy the front DE skid lasted about 8-9 gal before it broke & like Jason said you can see damage to it that may have ended my day if it was stock.The rears are up to your track,if you have lots of big rocks in the top of the dirt you would have to flip a coin on hinderence or savior.I have used the rear since my other brand buggy was new & at 15 or so gallons I'm ready to replace the chasis for other reasons but rear & front are like new.Loss of chassis clearance is not a concern unless you are fast enough to need the extra 1.5mm & thats faster than top of the grid sportsman in Socal.
