Need To Upgrade Rear Drum To Disc. On Dana 70 Per Poor Performance [ Yes Shoes Are Adj. And Drums Are A-ok ] Does Any Aftermarket Make A Conversion For This Year? And Or Proportioning Valve? Also Looking For Opinions On Best Exhaust Brake For 5.9- 93. If Exhaust Springs Need Replaced, Maybe It Be Better To Look At A Jake-brake Kit If Available, Instead Of Exhaust Brake. It Is A Old Truck, But Low Miles And Like New Condition, Will Never Sell So I Dont Mind Spending On Upgrades. I Would Appreciate Advice On Any Upgrades
yes you can convert the rears to disk but you cannot run dual wheels, there is no such thing as a jake brake kit for a 5.9 cummins, a TRUE jake works by actuating the valves mechanically, electrically, or hydraulicly, only an exhaust brake can be had for them, which works by air, vaccum or electric and closes a butterfly valve inline of the exhaust, and you can get a full set of intake and exhaust 60# springs for like 80 bucks most places, and they arent that hard to install, you can compress then springs by hand...........
