Video: Bolt-In Six-Link Rear Suspension For Mopar A-Body From QA1

QA1SEMA02

This is a 100% bolt-in kit, requiring only that a few holes are drilled. The rest bolts into place.

When QA1 introduced its new front suspension components for Mopar A, B, and E body cars, it helped put classic Mopars on the track. We installed the tubular front control arms and dynamic strut rods on our own Project Track Attack 1965 Belvedere and took to the track and saw a big improvement in both handling and lap times. QA1 was back again this year at SEMA 2014 to introduce a new rear suspension system for Mopar A bodies, and it completely blew us away.

The system is unique in that it is a complete, bolt-in system that does away with the factory leaf springs – which have been a detriment to getting these Mopars to handle better. There are a few different leaf springs on the market, but they all seem to fall short, and this kit solves the problem. The new rear suspension conversion from QA1, however, doesn’t require any cutting or welding of the new parts in order to install the kit.

Utilizing the factory leaf spring mounting locations, the conversion kit bolt's into place.

The original leaf spring mounting locations are used to mount the fore and aft control rods in a Watts-link type setup on each side. These assemblies bolt onto the factory 8.75-inch housing and are located where the factory perches are welded to the housing. The conversion won’t work on the smaller 7.25-inch rearend, so an upgrade needs to be done to the car if the smaller rearend is installed. The conversion is designed for the 3″ tubes on the larger rearend.

A pair of coilover shocks are included with the conversion kit, with your choice of adjustable or non-adjustable shocks.

To the front side of the differential is an additional pair of links that help locate the rearend, and they mount to the same front bracket where the leaf spring hanger mount is. With these six links being adjustable, a true, four-wheel alignment, as well as proper pinion angle adjustment, can be accomplished.

Included in the conversion system is a pair of QA1 coilover shocks, available in single-, dual-, or their new 4-way adjustable shocks. The ride height can be adjusted approximately two inches with the coilover shocks. A crossmember is mounted to the factory shock mount location, requiring drilling four holes per side to install the crossmember. The holes are drilled into the rear subframe, and requires no cutting or welding to install the crossmember.

The panhard bar helps to keep the rearend located side-to-side, with plenty of support bracing to keep it stable.

Locating the rearend side-to-side is a panhard bar that mounts solid to shock crossmember on the driver’s side, and to the rearend link on the passenger’s side. An additional support rod extends to the rear to keep the panhard bar located and firm. Incorporated into the kit is an adjustable sway bar that mounts to the rearend, with drop links mounting on the front crossmember bolts.

With the release of this new rear suspension conversion, it opens up the possibility for other models, as well as other makes, now that the foundation has been laid. What does QA1 have on the horizon for Mopar? They’re staying tight-lipped about future products, but as with anything that comes out on the market, the question always comes up: when will you make it for my car?

QA1SEMA13The QA1 Mopar rear suspension conversion was a huge hit at SEMA this year, and the crowd that gathered had lots of interest and wanted to know how it worked. SEMA awarded QA1 with a Global Media Award for this suspension conversion, and we expect to see big things coming from QA1 in the coming months, and look forward to continue to work with them throughout the year.

Pricing for the rear suspension conversion is around $2,995, depending on the coilover shock system selected. The system will be available soon, so be sure to keep tabs with QA1 on its website or Facebook page for all of the latest news and information on products, shows, and to be a part of their weekly trivia questions.
