Anyone have these?
I am considering getting a used IRS (for the cradle) in order to go back to stock bushings with posi lock and white line inserts/big Bertha bolts (based on some outstanding advice). Currently have the bmr derlin cradle bushings and aluminum diff bushings and the rear-end whine is loud. I don't mind some noise or clunks, but having both solid it sounds like a siren above about 40mph; and drives my wife crazy (annoys me some). Just about every combination I see on here adds noise, and the posi lock whiteline/big Bertha is probably a great compromise between strength and nvh; but I saw the gforce and they claim to have reduced nvh as a design criteria. It would be much less work and effort to do these; however if it is only a 20% reduction in gear whine then it will be more work when I end up with the other option.
