1973 Chevy C10 Buildup Belltech Sport Trucks

Last month we kicked off the Pickup Fix-up Tour by showing you the Brown Bomber in all its rusted and pieced-together glory. This month, you'll notice that much of the work done to my '73 Chevy C10 occurs somewhat out of order. That's due mostly to logistical issues involved in getting the truck from shop to shop. This was especially important in the beginning of this saga because the truck didn't run. Naturally my first goal was to get the truck running and then lower it. I swapped the worn-out 350ci small-block Chevy and TH400 trans for a GM Performance Parts LS327/327 crate engine and Gearstar-built 4L65E tranny in my buddy Tim's driveway. Once I finished the engine and transmission swap, I loaded the truck onto a trailer and towed it from Anaheim to Sanger, California. Belltech Sport Trucks is located six hours north and it was inside its shop that this truck really started to take shape.

Everything on the C10 was worn out when I bought it. Every bushing, every shock, even the leaf springs didn't want to carry much of a load. New suspension and rolling stock was certainly in order before I could even think about driving the truck safely down the road for any length of time. Keeping with the simple theme of this build, I resisted the urge to add an air suspension, and instead went with a performance-minded static drop kit. The truck needed an alignment badly and I wasn't about to align it at home, drive it to Belltech, drop it, then align it again, so I towed it to Sanger. Belltech offers several different drop kits for Chevy C10s of any vintage. I went with the double throwdown kit that featured front and rear sway bars, a bolt-in C-notch, 3-inch drop spindles, 1-inch coil springs, an axle flip kit, and new shocks for all four-corners. Tag-teaming the install, three of us dropped the truck in 10 hours and I hit the road for home. Next month, we'll focus on replacing the old, worn-out bushings with new performance pieces from Energy Suspension.

  • 1973 Chevy C10 Buildup Removed Wheels
    Tearing into the truck at Belltech Sport Trucks, in Sanger, California, we found out this truck was crusty! Maintenance was not in the previous owner's vocabulary and it showed. We started off by removing the wheels, freeing the cotter pin on the spindle, and removing the hub-style brake rotor.

  • 1973 Chevy C10 Buildup Ball Joints
    Separating the ball joints so that we could disassemble the front suspension was a chore that ultimately required a fork tool and a floor jack. Placing the jack between the lower control arm and the spring pocket gave enough leverage to pop the upper ball joint loose with a large sledgehammer aimed at the spindle.

  • 1973 Chevy C10 Buildup Factory Vs Belltech Drop Spindles
    Belltech's cast drop spindles relocate the spud a full three inches higher while placing the tie-rod ends parallel with the chassis at ride height. These are a great way to achieve a mild drop without inducing a ton of unwanted bumpsteer or problems with alignment.

  • 1973 Chevy C10 Buildup Factory Vs Belltech Springs
    If you look closely you'll notice that the new Belltech springs are the same length as the old ones. That's because at some point the previous owner took a Sawzall to the springs to drop the truck. The result was a mushy ride and zero load-carrying capability.

    Next up, the factory brake rotors were slid onto the new spindles and the outer bearings repacked with grease. A new cotter pin secured the spindle nut.

  • 1973 Chevy C10 Buildup Factory Vs Belltech Shocks
    Belltech's Street Performance shocks are not adjustable, but the engineering team valved them specifically for this application. The shocks are four inches shorter than the ones that were on the truck, which translated to more up-travel in the suspension than the truck had before.

    It's time to flip the axle from below the leaf springs to the top of them. Belltech has more jackstands than we've ever seen and they used them. Finally, the springs were slid out from under the axle tubes and then reinstalled on top using the flip kit.

  • 1973 Chevy C10 Buildup Right Side Angle
    At the time these photos were shot, the truck still needed new bushings installed throughout the front suspension, which are not part of the Belltech kit. It also needed an alignment, so you'll have to keep reading to find out how well the suspension works. The next stop on the tour will address the rest of the suspension and I'll finally get to drive the truck on the street.
