should I cut these cups

[pissonNOS]

heres a picture of the cups dont mind all the grease this is just temporary for this weekends car show then its all coming apart again to get cleaned and painted. But anyways would you guys cut these cups at all Im thinking if i do the bag will be rubbing too much, what you think?

[jlaird]

Well, I don't think I would cut them anymore. The part of the a-arm behind the bag in the picture slopes up, so I'm sure the arm is real close to the bag as is.

I'm at this same exact point in my build. This is what I'm doing, alot of work, but should be nice when done: I am going to cut a 9 inch hole in the arm, and insert a round piece of pipe. Then I'm going to weld a plate on the bottom of the arm. All 1/4 material. Should be stronger than stock and allow the bag to sit about 1.5-2 inches lower in the arm. Gonna start that today. I went to a welders supply store and bought an old tank for 20 bucks to get the 9" round steel.

that cup should be fine if you are running slambags becuase they are strong and thick incase the bag rubs alittle,, firestones would tear way too fast

oops.. that is yours.. i thought you said something about buying those cups.. i dont think you should cut them.. you could cup the upper and get rid of that plate if you wanna go lower..

i dont have any upper cups im only running the plate

I had the air ride kit originally. plate top, cup bottom. I switched to a cup up top and it lowered the truck a little over an inch. Cups are only $35 if buy, free if you are resourceful and can weld.

My set up now, i trimmed the spring pocket, puts cups up top, tubular arms, and 2" dropped McGaughy spindles. My truck will lay crossmember on 22's. I tried a friends 3" dropped belltechs and it will lay 24's. however, im just on 20's.

No bag should EVER be put in a situation where it rubs. Period. Slam Specialties doesn't have some kryptonite-based rubber in their bags.

I hear ya there XXL I was just reading on another post about the "Z" from what this guy is saying he obviously has a smaller diameter bag?

I've got cups that look identical w/ firestone 2500's and had em for 3 years, even daily drove the truck for a year and a half and never had an issue.
and anything will break if it rubs.

so your saying cut it?

[bedsled71]

im not saying its ok to let them rub but ive seen bags with bottom cups cut too short and do rub, i was saying the slam bags are thicker. and dont tear as easy if that was the case.. never said superman used them as a suit and thats why he didnt get hurt
