How much of a drop do I have? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

When I got my truck, it was already lowered. I measured from the ground to the center of the fender and I got 27" in the front and 26 1/2" in the back. I only measured the drivers side, but I'm only looking for a rough estimate on what kind of drop I probably have...

Thanks

measure from the center of the wheel to fender. the measurement from the ground to fender will depend on your tire size.

First of all, why is the back of your truck lower than the front? Anyways... Look at the spring hanger on the rear. That's what mounts the front of the rear leaf spring to the frame. If it's level with the frame, that's 2 inches right there. If the rear shackle, which mounts the rear of the leaf to the frame mount, is about 4 inches long, that's another 2 inches. The front is trickier due to different aftermarket spring heights, and spindle drops. By looking at the very small pic of your truck there, I'd guess it's a 5/7 drop, maybe 4/6 depending on your tires. Is there a "C-section" cut into the frame over the rear axle?
