Sold my 95, bought an 06, Going to the Cummins plant tour in June, Wondering what spares I should carry. Have just changed all fluids, synthetic in 48RE & rear axle. Replaced U joints with Spicer and balanced shaft. Do I need a spare lift pump or should I change to a Raptor? Water pump which one is best? Any other advice is welcome. Approx. 100K on truck. Planning on a oil by-pass filter, GDP or ?, also checking #4 Injector line.
