Mopar has always stood out among the rest of the muscle car market for a litany of reasons, one of which being its use of the unibody platform and unique torsion bar-and-leaf spring suspension. Over the years, this suspension arrangement helped give Mopars a leg up on the competition, but also hindered its place in the higher tiers of racing and modification – particularly as aftermarket manufacturers poured more effort into coil-over technology for autocross and road course racing.

Thankfully, a robust aftermarket has come to the aid of the unibody Mopars in recent years and we get to reap the benefit of it. QA1 has been building industry-leading performance suspension components for Mopars for a decade, but only recently have exploded on the scene with a whole catalog’s worth of rack-and-pinion conversion kits and front-and-rear full coil-over and 4-link suspension packages. This herculean effort has rocketed QA1 to the head of the class with a full range of handling parts.

Whether you’re looking to shave some weight from your street/strip machine and need a lightweight tubular K-member, upper and lower control arms and aircraft-grade strut bars, tie rods or sways – QA1 has it ready and waiting. And if you’re wanting to hang with the OPTIMA road course boys, QA1‘s Stage 3 coil-over kits will get your Pentastar carving like it’s on rails. Based out of Lakeville, MN, all of QA1’s products are extensively tested for exact fitment and finish.
