Purchase went off without any issues. Had previously used CPP Diesel and had some issues that were eventually worked out. Decided to try again and this one went without issues.

I have followed your site for years and recently purchased my dream truck... a 99 cummins 5 spd. I have been on everyones site but CCP's flows the best, the prices are the best, I truly appreciate that. I like the ability to drop in a part number and BAM get the price and move on. I will be back. Thank you!!
