Drop Your C10 Correctly Without Losing Ride Quality or Handling

If you wind the clock back to the 1940s and through most of the 1980s, your typical full size pickup truck was designed, built, and used for hauling. Be it delivering products, hauling equipment on a trailer, or just being the trusty farm truck that many of you probably learned to drive with on your grandparents back forty, the humble pickup was never really thought of by the Big Three as a cool ride that could be hot rodded. They were sold as workhorses and that’s what they did. That is until second, and now third generation family members are pulling these old trucks out of their barn-induced hibernation and turning them into some sweet rides to go cruising Main Street USA.

One of the first things classic truck owners do is give their ride an altitude adjustment by dropping it a few inches. The lowered ride height not only looks perfect, but leveling the truck takes a lot of the “work truck” look out of the equation. Not to mention, the lowered stance helps with handling and traction as well. Chevrolet’s immensely popular classic C10 pickup is super-hot with all manner of drivetrain upgrades, interior updates, and more available. Our C10 lowering kit 3/5 drop springs provides that extreme lowering look while being a direct replacement and retaining the stock-like spring rates. Our C10 lowering springs are easy to install, include the rear spring retainers and Belltech’s Nitro Drop 2 shocks front and rear. A few hours with a pal and some hand tools and you’ll have your C10 hitting the road looking on point and ready for the next upgrade.

Quality Coil Springs and Retaining Hardware Make Your C10 Drop Easy

Our Chevy C10 lowering kit springs feature high grade steel construction and the front springs begin with 3/4-inch spring wire material. They are wound in a standard fixed spring rate of 1,100 lb/in with factory end pigtails and a free height of 11-inches. These springs provide a 3-inch drop in the front of your C10 and work with stock or aftermarket control arms.

The rear springs in our C10 lowering kit are made from the same high-quality steel but utilize a smaller .600-inch diameter wire (that’s just under 5/8-inch). These rear springs are also designed at a fixed rate and come in at 300 lb/in for a 5-inch drop in the rear of your C10, which levels these trucks out nicely. The free height of our rear springs comes in at 9-inches. Both front and rear springs are provided with a long-lasting gloss black powder coat that will go with any suspension/body/frame color and make the springs easy to keep clean and looking good. The included rear spring retainers ship in primer, ready for your finish painting, powder coating, or other surface protection, and include all new Grade 8 mounting hardware so you don’t have to worry about trying to clean up decades-old hardware with rusty threads or other damage to them. Due to the extreme drop of our rear springs we highly recommend installing a C-notch kit at the same time to provide plenty of frame clearance.

We offer several C10 lowering kits with different drop levels and additional components like shocks, a track bar, and more. Our C10 lowering kit 2/4 drop springs, shocks, and relocation brackets is just one of the many kits we have for the popular Chevy C10 drop kit category. Of course, we also have a full line of sway bars, bushings, and more to completely revamp your suspension while you’re creating your lowered C10 project.

Factory Like Ride with Better Road Feel Thanks to Belltech’s Nitro Drop 2 Shocks

We have added some great gas charged twin tube shocks to this C10 lowering kit by way of Belltech’s Nitro Drop 2 shocks. These shocks are valved to provide a smooth and comfortable ride, while enhancing road feel by better controlling the spring’s motion over road imperfections. Belltech engineers increased the low-speed compression of these shocks while tweaking the rebound forces. Designed specifically for lowered pickup truck applications the Belltech Nitro Drop 2 shocks feature hardened chrome 12.5mm shock shafts with triple lip NBR rod seals and a Teflon guide bushing. Inside the 45mm wide body (for extra oil volume) are 30mm shock pistons with low-friction Teflon seals. These Belltech Nitro Drop 2 shocks are direct replacements for your stock shocks and bolt right in with no drama.

Our rear shock relocation brackets reduce the installed shock angle, rotating the shock to a more vertical mounting position, which provides for more shock travel and better handling. The brackets are black powder coat finished and include Grade 5 mounting hardware. Simply grind/drill out the rivets retaining the factory rear shock brackets and bolt these brackets into place on the rear axle and frame crossmember for an easy upgrade. New U-bolts are included to make the job easier! We recommend these brackets for any C10 that is lowered three or more inches in the rear.

A DIY Project Easily Accomplished with Hand Tools

Dropping your C10 with our C10 lowering kit 3/5 coil springs is a great basic project for a Saturday afternoon with age-appropriate kids or grandkids to help sling some tools with. Using nothing more than hand tools, a floor jack, and some jack stands (don’t forget the tire chocks for additional safety!) you can knock out this spring and shock swap in just a couple of hours. The stock front coil springs do have some tension on them and take a little finesse to work free, but the rear springs practically fall out once you take the weight off them and unbolt the spring retainers. The shocks are simple nut and bolt work as well. This is a project that will net you better handling and that perfect down low ride height that will make your C10 stand out. Best of all, you know it’s done right because you’re doing it yourself!
