MUSTANG 8.8" SWAP KIT
This control arm kit from SSM
Performance is designed to bolt a Ford Mustang 8.8" rear end into a
1978-1988 GM G-Body; this includes Monte Carlo, Malibu, El Camino, Regal, Grand
National, Grand Prix and Cutlass. These upper control arms are built at the
correct angle to attach to the G-Body chassis. The relocation bracket kit will
allow for proper instant (geometry) changes. The adjustable lower control arms
allow you to center rear. These control arms are a must any time this swap is
being completed. Using factory control arms will cause drastic rear end bind
and incorrect driveline angle, this leads to traction loss, vibrations and
Our extreme duty control arms allow for pinion angle adjustment for reduced vibration and increased traction. Our exclusive Polyurethane bushings offer controlled positioning during suspension travel which improves traction and rear suspension efficiency. This item is a must for any high horsepower
Benefits: Pinion angle adjustments for improved traction and reduced wheel hop. Heavy duty construction for long lasting durability on the street or track. Complete ready to bolt-in and most kits includes polyurethane rear end housing bushings.
Stock control arms are on the borderline of junk, bushing deflection and rusting weak stamped material add for traction loss and poor handling ability. Our tubular control arms are designed to give you the best of both worlds, whether your car is a weekend cruiser or a weekend track addict we got you covered.
These are truly overkill! All grade 8 hardware is included. Made in USA!
All parts are custom built in house. Indianapolis Indiana
Please give us a call before your purchase to make sure this is the right kit for you. We have several kits available for different types of cars.
Features and Benefits:
Reduces Wheel Hop
Improves Handling And Stability
Stronger Than Stock Arms
Features TIG-welded Construction
Pinion angle adjustment
Sway Bar Ready
Instant Center Relocation and Why It’s Needed
The basic information regarding instant center is the same for all cars, but for this discussion, we'll focus on the factory-designed four-link system. The instant center (IC) is an imaginary point defined by extending the line of the upper and lower control arms forward until the two lines intersect. By changing the locating points of either the upper or lower control arms, the IC can be moved longitudinally (fore-aft) as well as vertically. Moving the instant center closer to the rear of the car reduces the leverage on the rear axle, reducing and eventually eliminating the car's tendency to squat. There are two basic ways to change a Chevelle's IC position. The OLD SCHOOL "No Hop" bars relocate the rear-axle mounting point of the upper control arms higher, which shortens the IC. The popular approach is to drop the lower rear mounting point of the bottom trailing arm. This is the approach taken by SOUTHSIDE MACHINE PERFORMANCE WITH OUR 4 HOLE RELOCATION BRACKETS.
As the instant center is moved toward the rear by altering the upper or lower control-arm mounting points, this has an effect on tire load, or the "hit" on the rear tire. If you are using a sticky rear tire like a wrinkle-wall M/T E.T. Street or a pair of slicks, moving the instant center rearward will apply more leverage to the rear suspension, reduce the squat, and take maximum advantage of the wrinkle-wall tires. If a set of stiffer-sidewall drag radials are used, positioning the instant center back from its stock location--but not as far back as for a wrinkle-wall tire--would be beneficial.
The height of the instant center will also move as you reposition the control arms, and this affects average tire loading on the rear tire. If you draw an imaginary line between the tire contact patch to the car's center of gravity (CG), this is the 100 percent antisquat line. If the instant center is located above this line, antisquat will be more than 100 percent, while an instant center below the line is less than 100 percent antisquat. Theories abound on the proper location of the instant center, and this will change based on power, tire condition, track conditions, and perhaps a dozen other variables. This is just a hint of what you can learn about instant centers and traction. If you're into maximum traction, there's a ton of material to learn about putting the power to the ground.
