Description

Upgrade your square body Chevy C10's driving feel and performance while getting the perfect stance with QA1's 1973-1987 C10 coilover conversion systems. The kits come with everything you need to convert your C10's front end to coilovers and a tubular crossmember with rack-and-pinion steering. These coilover conversion systems are a great way to overhaul your suspension in one go, giving you adjustable ride height to achieve the perfect stance with up to 8 in. of drop—all while dialing in the ideal ride quality and performance for your application while also reducing weight 140 lbs. over stock. Order the QA1 1973-87 C10 coilover conversion system recommended for your year/make and model vehicle.

Product features and details:

* Powered rack-and-pinion offers quicker steering and a tighter feel. Plus, increase steering angle when fitting larger wheels and tires, and improve geometry for enhanced drivability
* Increased Ground Clearance: The crossmember and control arms make your undercab rails the truck's lowest point—new upper shock mounts increase travel for a great ride and performance, even at low ride heights
* Single or double-adjustable shock valving offers independent rebound and compression tunability—great for trucks that will see track time or drivers who really want to dial in ride quality on the street
* Easy, Bolt-In Installation: The crossmember comes powder coated and ready to install—no need to cut or weld your frame—it easily locates the steering rack, and you can choose mounts (sold separately) for common engines
* Modular Engine Mounts: Choose from modular engine mounts (sold separately) that allow you to reuse your existing transmission mount and driveshaft (kits are available for small block Chevy, big block Chevy and LS applications—DIY mounts are also available if you want to customize the location of your engine
* Front Sway Bar: The optional front sway bar (sold separately) adds even more cornering capabilities—it reduces body roll and keeps your tires planted to give you more grip in the turns

Fitment Notes:

* If you already have QA1's coil-over system, you can find retrofit kits to use your existing components
* Total drop range depends on wheel/tire fitment
* Will require you to trim inner fenders
* Engine mounts are year-range specific to maintain OE bellhousing location
* Optimized bump steer settings require at least 18 in. wheels
-- 18 in. wheels can run up to 6 in. of backspacing
-- 20 in. wheels can run up to 7 in. of backspacing
* Requires use of 1973-1987 C10 spindles
* May require different headers and oil pan (Stock SBC and BBC pans fit)
* Steering shaft is not included
* May require new power steering hoses depending on fittings, pump, and engine placement
