Replacement Poly Bump Stop for Kryptonite Upper Control Arms for 2001–2010 Chevy/GMC HD Trucks

I bought these to replace the ones that came with my upper control arms. The ones I got with my upper control arms didn't last a year. Basically one off-road trip destroyed them. These seem like a wear item for rigs that off-road frequently. It would be nice if there was another solution for limiting the travel rather than something I'm going to replace every trip.
