I'm sure most who have the RPG traction bars also have the hydro/pneumatic bumps, but thought I'd ask. I've finally found enough axle wrap (in our sand island in our park of all places) to warrant a solution. The Deavers hook up well enough on pavement, but strangely I get more grief in the sand. Anyone running the RPGs traction bars with SDHQ Offroad OEM Bump Stop Plates (already have plates with Deavers)? I think its an impossibility, both may occupie the same space but not sure.
