shock bushings

When I bought my ranchos a while back, the upper front shock bushings was a nice 2" (or 2.5") polyurethane bushing. Now it seems that all shocks come with little dinky bushings: does anyone have a line on better shock bushings? I think ZJ's or WJ's had big bushings: can anyone confirm or deny that?
I have also checked out energy suspension but all that they have is a wimpy 1 1/4" and 1 3/8" bushings.
