Description
Improve Traction. If you're not "hooking up" off the line then a set of J&M Weight Jacker Rear Lower Control Arms are the answer to your problem. These lower control arms will eliminate wheel hop, and improve traction keeping your Mustang's rear end planted for straight-line traction and cornering performance.

Height Adjustable. J&M Weight Jacker Rear Lower Control Arms allow the driver to adjust the rear ride height for perfect launches every time. Lower your Mustang 1" or raise it by 2" by using a NASCAR style weight jack system.

Superior Construction. J&M's lower control arms are manufactured from high strength 2" round steel tubing, making them lighter, stronger, and more resilient to bending than the competitors rectangular or square tubed control arms.

Bind-free Design. These control arms feature a Patent Pending 3-piece Poly-Ball bushing on the chassis side that incorporates a very hard inner polyurethane ball surrounded by two soft polyurethane outer cups. The axle side features a Chromoly Teflon lined spherical bearing that eliminates any unwanted bushing bind and deflection. The result is great traction during straight-line acceleration and predictable grip during hard cornering.

Application. These J&M Weight Jacker Rear Lower Control Arms are designed for street or race use on all 1979 to 1998 Mustangs, including the LX, V6, GT, and SVT Cobra models. Sold as a set of two control arms.

    New J&M Control Arms

    Great product , the welds were perfect , the install was easy took about 3.5 hours with hand tools. I recomend when greasing the bushings , go light on the grease because when pushing the bushings on the air gets trapped in the housing and bushing pushes out ( again great welds and finish ) love the way you can simply adjust the spring perch anytime. I would recomend these to any fox owner that wants a straight even launch at the track. Thank American Muscle !!!!

    Great Product

    After waiting for the back order i finally got my control arms. Install was less than hour. The welds look like they have strength and quality in mind. Unlike cheaper knock offs or sub par copies. Can't wait to see how they perform at the track. As for stance having the adjustability is a huge plus. I recommended these to a friend who has purchased these and is awaiting arrival.

    ride height is easy to adjust.

    after installation, car seems to hook a little better and launches straight Only downfall is a little noise from spherical bearing on rear side of control arm.

    J&M makes a quality product!

    I installed both the J&M weight jacker rear lower control arms and upper control arms. The install went smoothly and the lower control arms gave me the adjustment needed to give my car the stance I was looking for. At the track my 60ft times decreased from an average of 2.35 to 1.9, which makes a huge difference in the 1/4 mile. I would definitely recommend to others as it works great at the track and does not effect drivability on the street.

    Get Hole Shot

    Replace those week factory control arms with these heavy duty pieces. They are solid and super rigid. Plenty of traction with these parts off the line and much improved cornering capability. Get some adjustable uppers to dial in lowered cars and tie it all together with an upper strut brace.
