2003

Hey all! New here & trying to narrow down an issue with my 2003 CR. Any info is greatly appreciated! Rather loud slap/clap noise coming out the tail pipe; no exhaust "restrictions". Can't hear anything odd under hood. Truck has 317k on the clock with no major engine work done except injectors...

Hi all, I would really appreciate some help with this issue I'm having. I am working on a 2003 Dodge 2500 with a 5.9 Cummins. 229,000 miles. Initial complaint was a really rough idle and lots of white smoke. I did a cutout test. All 6 cylinders fluctuated at idle when I cut them out...

I am very aware that they DO NOT make a Compression brake (Jake Brake) for the 2nd gen Cummins. Question is, Is there that much difference as far as the top end of the motor that using a Loadleash Engine Brake meant for a 2003 and making it fit on a 2001 block? I haven't played around a 3rd gen...

NOTE: The majority of this first post consists of the email I sent to the technical reps at Geno's Garage, as well as Borgeson. They've offered as much assistance as they can, which I am very thankful for, but I still have not been able to resolve the problem. So I have a little bit of a...

I've been having a very annoying problem with the stock (Karr) anti-theft sytem in the truck. The system will go into alarm at random times, but only when my truck is parked at work! This is incredibly inconvenient because I work at a firehouse, and the alarm will sound almost always at 11:00...

Hello all, I installed a KORE leveling kit on my '03. I had measured the distance from the ground to the bottom of the fender, it was 39" before starting the installation. The install went fairly smooth, but after it was all done the new measurement was 44. 5" from ground to bottom of fender...
