Have a bone stock RMK 700-2009 with 155. Put a timbersled intake on it, and a SLP pipe and Can. I wanna get more power to the ground by tuning the clutching. I see the stock primary spring is a 140-330. I have two primary springs to try out: black/pink SLP - 120-340 and blue/pink 140-340...
Hey hows it going. I have owned 3 cummins trucks now. A 2001 six speed, a 2008 mega cab 3500 6.7, and a 2006 5.9 mega cab 3500 all 4x4's. all three have been fricking mules. other than the dodge having ball joint issues on their trucks, the motors are the epitome of a diesel. diesels are meant...
ok, the clutching part of it i am working on.... any ideas on the ideal combo???? i hear the black/pink primary spring or the blue/pink primary spring are money for that sled. porting i know nothing about, is their a trick to it??? or more specifically, how to on the porting????
