Thankxxx man. Did some research today on nodular iron vs factory cast iron and the nodular seems way stronger and Dr. Diff agrees and for $300 bucks w/billet caps and adjusters, I can`t go wrong and don`t want a truck or ford rear under my car. Mine has lasted longer than most into the 9`s at 3200+ lbs w/30 spline axles so this along w/35 spline axles, a new spool and around 3000 lbs.(for now), I should be golden...........
I have been running that case in the 489 style, 4.30 gears, and 35 spline set up for 3 or 4 years. Ring and pinion life sucks for me at about 80 passes.
My Dart is about 3300lbs, normally 1.38-1.42 60' times
A 9" is going under the car soon. Save your money Dom
