"Are you getting their whole kit or just the shocks? I imagine they work the best in conjunction with the coil springs since they both contribute to ride quality."
Their "prerunner" kit is their 2.5-inch long-arm lift, Elka shocks, and the speed bumps. I'm getting the Elkas to replace the Teraflex 9550 gas-charged twin-tube shcks that came with my Teraflex 4-inch short-arm kit.
My motivation is to smooth out "normal" and "rough" roads and trails. The feedback on the forums for the Elka shocks is very good. Think I've only hit the bump stops a few times and I'm not really a "high speed"/prerunner kind of guy so I can live without the speed bumps. The remote reservoir is certainly overkill for my needs.
