Control arms ??

My truck isn't bagged and I don't think it'll be bagged in the near futur. But I'm driving it the hardcore way (2"1/4 from the ground) and the lower control arms hit the frame some times when I hit a bump. I know I can notch 'em a bit and the problem would be solved...But I was wondering if anyone make lowered control arms for coil springs. I know there are a lot made for airbags... there must be some made for the coil springs. If you happen to know please help me out!!

Thanks

Oh, it's a 90 GMC Jimmy btw
