This Old Dodge

In today's economy, is it worth it to refresh and rejuvenate a worn-down 12-valve?

April 2009 Feature

Ahh, the 12-valve 5.9L Cummins. Probably the most sought-after diesel power plant when it comes to making big, reliable power. The 1994-98 Dodge Ram was very popular when it was still being built and has continued to be even after 10 years of retirement. None of this emissions stuff, no fancy electrical sensors, PCMs, IDMs or FICMs-

just some throttle linkage between your foot and an injection pump. The turn of a screw here, adjustment of some springs there and you're basically on your way to making decent power.

 

With the recent fuel crisis and price jump in new trucks, we've seen an overload of e-mails and letters from readers looking for ways to get more out of their current trucks. Whether they have fuel mileage or performance in mind, it seems readers just want to see inexpensive and reliable ways to make their older trucks better. We've done builds on a couple Power Strokes, some 24V Cummins stuff and even some extensive Duramax builds. We figured it was about time to go back to the original leader in aftermarket diesel performance, the p-pumped 12V Cummins.

This small population town is the headquarters for fusion bumpers, a custom bumper manufacturer for nearly 15 years...
