rear 7" drop with 20's - The 1947 - Present Chevrolet & GMC Truck Message Board Network

oldschool18 · 01-18-2014, 01:12 AM

I'm slowly getting my frame back together and I'm doing a 7" drop on the rear.....5" springs and 2" blocks. Now I was wondering if someone with a 7" drop and 20's could get me a measurement from the bottom of the frame to the ground at the rear of the frame? It just doesn't seem low enough, now I have no body on the frame but I still would like to see how close I am or maybe where everyone else is at.

Thanks

A pic to give you an idea of what it will look like. Im running CPP 7 inch drop coils in rear with shock relcocaters, and kony drop shocks. Hope it helps

Opps here is the pics.

thanks Scott but I still need a measurement, and your truck looks really good too.

I ran out to the shop and mesured. From the very end of the rear from rail to the ground it was 16 and 3/4 inches.

thanks Scott......I think I'm between 22 and 23, now like I said I don't have the body on it and I don't think with the body on it is going to drop another 4 or 5 inches. Scott it looks like you got 40 series tires on your truck, I got 45 series on the rear so I would lose about 1.5" if I went to 40's. I wonder if I was sent the right springs?

Scott, your truck looks awesome!

Would you mind posting a few more pictures? Maybe a side view and a few different angles.

Thanks,
Mike

Here are a few more. Some are from before the restoration but it has the same drop before and after.

that is a nice truck Scott and thanks again for the pic's and the measurements.

An axle to frame measurement would take tire diameter out of the equasion. I know with my 6" drop the axle touches the bumpstop with a full gas tank.

mines about 2" away
