PerryParts bumps are another option. I ran them on the front of my GX460 and they were like pillows.
I ran Durobumps on the rear only because PerryParts didnt have them yet(I was one of the first buyers) and they were much better than stock.
One thing I didnt love when Durobumps reps were arguing on GXOR about being "better" than their competitors was that they claimed their bumps were designed to provide the same stiffness at the same suspension position as the stock bumps. The problem is that the OEM bumps(at least on the GX460) literally needed like a 30 ton press to even move slightly and they caused the GX460 to lose almost 1" or maybe 1.5" of wheel travel. Assuming the durobumps were as stiff at the same suspension compression, they are sacrificing uptravel. I even asked Durobumps why matching the stock bump stops was the best option and they didnt have a good answer.
If you buy into PerryParts marketing, their bumpstops are variable rate, and so they will act stiffer on hard hits. When you are slow crawling the stops will have more give and in theory allow more travel.
This video shows what I mean about the factory bumps:
Even with the bumpstops removed, the shocks still dont bottom out before the CV starts to bind.
