Enjoy The Benefits of a Coilover Front Suspension with Our Bolt-In C10 Conversion Kit

Coilover shocks provide not only better ride and handling but are also known for their ability to easily change spring rates as well as allow easily adjustable ride height changes. All it takes is a quick look under a race car, Pro Touring muscle car, or a pre-war hot rod to spot a set of coilover shocks. However, these applications often feature an OE shock (or strut) mounting position that allows for a coilover shock (or strut) to simply be a direct bolt-in replacement. That or the vehicle may be running an aftermarket full frame or front subframe setup designed for coilover shock use. In the case of some vehicles, like the First, Second, and Third generation Chevy C10 suspension, the OEM front suspension design does not provide for a bolt-in replacement shock solution, as the front shock is mounted between a frame stud and the lower control arm outside of the upper and lower control arm and coil spring arrangement. While this makes servicing the OE shock easy, the aft mounting points do not allow for a simple C10 coilover kit conversion. Our bolt-in C10 coilover conversion kit provides a cost effective coilover shock solution using easy to install upper and lower adapter brackets mounted to the lower control arm and the truck’s frame.

Laser Cut Steel Brackets Provide a Precise Fit and High Strength Mounting Solution

Relocating the shock mounting points within the lower control arm and the frame’s original crossmember’s coil spring cup requires a strong mounting solution that will not flex or fail under not only static ride height, but during suspension articulation as well. We designed our bolt in shock brackets for C10 coilovers with the utmost strength using a combination of laser cut struts made from 5/16-inch thick steel plate welded to a 7-gauge laser cut and press bent mounting plate. The complete assembly is then fixture welded for accurate fitment and placement of the coilover shock assembly.

The mounting plates are designed to be used with our C10 tubular control arms and align with factory mounting holes for the OE upper control arms on the frame rail and the new lower control arm’s steel spring cup support plate that spans the tubular arm. Drilling/grinding of the old upper control arm rivets and grinding/cutting a clearance opening on the crossmember’s coil spring cup for coilover shock body/spring clearance is required and can be accomplished with standard automotive tools like a die grinder, small belt sander, or rotary tool. No welding or other fabrication needs are required to add our C10 coilover kit. The upper and lower coilover mounts are powder coated satin black for a great appearance and corrosion protection from the elements. All mounting hardware is included for a complete bolt-in C10 coilover conversion mounting solution.

Complete The Job with Our Tubular Control Arms and AFCO Pro Touring Coilover Shocks

These shock mounting brackets for C10 coilovers are designed to work with our C10 tubular control arms (available for ’63-’70, PN 91039300; ’71-’72, PN 91039301; and ’73-’87, PN 91039302 C10 pickups) that are sold separately. Stock stamped steel lower control arms or other brands of tubular lower control arms are not guaranteed to work with these brackets for proper fitment and shock mounting angle. If you’re already using our tubular control arms on your C10 all you will need to do is swap the bolt-on lower control arm spring pocket for our coilover shock lower mounting bracket and then perform the necessary upper spring cup modifications for coilover shock clearance when installing the upper coilover shock bracket.

The AFCO 1340CT Pro Touring shocks are the perfect choice to enhance the ride and handling of your C10. We designed our C10 coilover conversion brackets around these shocks, however, you may use any coilover shock with the same specs, which is 14-inch extended length and a 4-inch stroke with 1-inch wide rod ends top and bottom. For C10 coilover kit springs, we recommend something with an 8-inch free height with a 2.50-inch inside diameter. Spring rates will vary depending on your application, but generally 650-850 lb/in rate range is best for the C10. We offer Eibach and Ridetech fitments to complement the AFCO 1340CT recommended coilover shocks for this conversion kit. Alternatively, you may choose to go the kit route (PN 91039304) with these coilover shock brackets, the AFCO coilover shocks, and your choice of Hypercoil spring rates, along with the correct tubular control arms for your year truck and save yourself the hassle of choosing everything separately.

Give your Chevy C10 suspension the ride and handling it deserves along with the adjustability of custom ride height and spring rates that coilover shocks are known for with our easy to install C10 coilovers kit.
