A Good Chain Can Make All The Difference

I cannot describe the feeling but I know you’ve felt it before. The feeling you get when you know something is enormously wrong but just before the full impact hits you. It was only five fifteen but it was dark outside. I stepped outside my truck and was looking back at the trailer. From where […]

Exhaust Stacks

Two Wheel Drive Low

Installing a Throttle Body Spacer

That I take my vehicles to a mechanic, even for minor problems, makes me spoiled in some respects. Though I have disciplined myself to change wiper blades, fuses and light bulbs. Nonetheless, when I looked the throttle body spacer over, I took up the challenge to install the unit myself. This isn't a hard one. […]
