Video: AmericanMuscle.com Drops A Challenger With Eibach Sportline Springs


AmericanMuscle (AM) has shown time and time again that they’re all about providing products that are both show and go. In a recent video, AM’s Adam Maqboul installed and reviewed the fresh and functional Eibach Sportline lowering springs on an outrageously orange 2013 R/T.

Made for 2008-19 Challengers except Hellcats and Demons, the Sportline springs are powder-coated race-ready red and lower your late-model by about 2.1 inches. An equal drop at each corner preserves the slight factory rake. Just like the stock springs, they’re made of high-tensile strength steel. Unlike the factory pieces, the Sportline’s progressive spring rate allows for varying levels of ride performance.

“It’s not all appearance changes when it comes to lowering springs. Lowering your Challenger is going to help with cornering abilities, suspension and handling feel, performance on the track and, of course, the progressive springs are going to be a lot more comfortable on the road while also progressively getting sportier and tensing up under heavy loads,” Adam explains.

AM estimates installation time to be about 6 hours, assuming you have a spring compressor and lift available. Adam details the necessary tools, torque specifications, and disassembly/assembly steps required to do the job yourself. Once the deed is done, a trip to the alignment rack is highly recommended. “After you tackle this installation, whether you’re doing it yourself or taking it to a shop, make sure you’re getting your alignment checked or redone simply because any time you’re disconnecting your cradle at the rear end or taking your struts out, you are going to mess up that alignment just a hair.”

That restoration experience lead to pursuing a degree in Mechanical Engineering and a career in manufacturing. Since then, the garage has expanded to include a '67 Satellite, a '72 Scamp, and a 2010 Mopar '10 Challenger.
