You might think with the last chapter of gasoline fed Mustang’s being unveiled earlier this year that the aftermarket might tone things down a bit. Wrong. The aftermarket remains a primary source of goodies to make the muscle car of your dreams come to life. Roush Performance in particular is continuing to supply new and updated products, this time around, they’ve announced an S550 Ford Mustang Magneride Suspension Kit.
The suspension kit is applicable to 2018-2022 model year S550 Ford Mustang muscle cars that are already equipped with the Ford Factory Magneride Suspension System. The $649.99 kit includes both front and rear lowering springs, Magneride calibration card, as well as some Magneride badging to let people know your aftermarket suspension preference. The springs themselves are covered in a red paint so as to stand out when someone decides to take a peek under the fender. The springs lower the vehicle’s ride height by 30mm or 1.18-inches for the metric system advocates.

The spring rate differences break down based on engine size. For 4-cylinder engines, you can expect spring rates of 135 lbs per inch on the front, and 570 lbs per inch in the rear. For eight-cylinder power plants you can expect a little beefier 230 lbs per inch in the front, and 570 lbs per inch in the rear.
Roush rates the installation of the springs as a four-hour intermediate do-it-yourself job that can be accomplished using standard garage tools as long as you have wrenches, an impact gun, loctite, an air ratchet, hammer, trim tool, and a variety of sockets. If you don’t have those tools, don’t want to ruin something, or simply don’t want to take orders from an instruction manual, Roush’s website has a dealer locator that points you in the direction of a certified technician presumably at an additional cost to you.
