Re: 1999 GMC Suburban K2500 DD
The wheels look real nice. It warmed up to the 40s here yesterday so I fired up my 99 k2500 diesel after its winter nap. Any chance you want to part with the front bumper grille guard?

OE front bumper and the grill guard are long gone, they sold within days of coming off back in 2020. This thread has some age on it now, I just haven't been doing a great job keeping it updated. There is a much more in-depth thread on gmt400.com.

I really like this truck and the functional updates. Where did you get your rear wheel spacers? I have looked into them and either found questionable sources or very expensive sources. Did you have trouble with the PY0s or did you just want to update the look of the wheels? You mentioned an ECM upgrade and I was curious what you would gain from that. I'll bet that it is a very nice truck to drive with the comfort, power, and ride feel. Last edited by LT7A; 03-19-2022 at 04:09 AM. |

https://www.gmt400.com/threads/1999-...2500-dd.48861/ I appreciate the comments. Rear wheel spacers are Stahl brand, made out of steel. Stahl is the heavy duty division of Bora brand spacers. Bora's are considered the best in the industry. No issues with the PY0s, I wanted the rear track to be as wide as the front. Blackbear did the tune on this one. It improves fuel and timing maps, shift points, removes torque management(if wanted), etc. Mine drives extremely well and has made 13.6mpg running down the interstate at 73mph, fully loaded down with family and gear. For comparison, my 2011 1500 Suburban with a 5.3l would only get around 14.4mpg in the same instances, and it had far less towing capacity and comfort. (it was tuned and had worked exhaust as well)
