The 1947 - Present Chevrolet & GMC Truck Message Board Network - View Single Post - 67 C10 Lowering + Wheel/Tire Sizes and Other Recommendations

laketboy · 08-09-2017, 05:39 PM

New to the C10 forums(s). Seems to be no shortage of interest in the 67-72 C10 with 3-4 forums on the Internet.

My son has recently acquired a clean straight 1967 C10 long bed (and purchased a used/running LS engine and trans for it. A local guy who is very experienced with C10's has chopped the frame and bed to convert to short bed. As expected, I've spent a couple of hours searching the 3 major C10 forums and learned a lot, but would like some suggestions in the area of suspension drop, ride height, wheel and tire sizes and parts and or kits that get the job done on a modest beginner budget (read: not the cheapest way to go, not the BEST/MOST expensive).

Basics: He does NOT want the LOWEST drop possible. He wants to actually use the truck occasionally to haul basic stuff. Seems what I've read tells me the stock rear is 2" higher than front and most popular drops are front/rear drops of 2/4", 3/5" and 4/6" to achieve "level" truck". He seems to be aiming at the 3/5" drop based on recommendations by guy doing some of the work. Plans are to go with 5 lug on all 4 and disc brakes (at least up front). Interest in wheel diameters between 17" and 20" (old school dad prefers 17-18, but has 20" on new 2016 Silverado levelled with 1.75" front rise using Bilstein adjustable to level)

All this said, what are some suggestions of HOW to do this? 2/4" drop vs 3/5" drop pros/cons? Parts and work required for either? What (max) wheel and tire size combos work to fill wheel wells for both 2/4" and 3/5" drops without rubbing issues?

I've read very BUDGET ways to do things and EXPENSIVE (BEST?) ways to do all this. I don't think airbags are in the budget at this time, BUT if able to acquire good USED (craigslist and eBay are great), maybe.

BTW, I've found the following suppliers with seemingly top notch ($$$) products

Summary
2/4" vs 3/5" drop parts required
Max Wheel/Tire sizes for either 2/4 and 3/5 drop
Disc brake recommendations
Steering component change recommendations
LS engine/trans mount recommendations

Thanks in advance for your recommendations based on experiences
