Fits 1999-2004 Mustang
What's in the Box
(2) Lower Control Arms
Looking for the ultimate way to improve your 1999-2004 Mustang's launch? Well look no farther than these J&M Weight Jacker Control Arms! Made with a tubular design, these control arms are stronger, have better torsion rates and are also lighter than most rectangular design arms.
Revolutionary 3-Piece Poly-Ball Bushings! This combination allows the bushing to articulate like a spherical bearing during cornering but the hard inner ball does not allow the bushing to deflect during acceleration giving you great traction during acceleration like solid bushings but remains completely bind free like a spherical bearing during cornering for great predictable traction in the corners.
the arms work just fine as advertised, but the three piece bushings are the worst possible design and are extremely difficult to install. there is a grease fitting on the adjustment stack where a setscrew should be to hold the adjustment once you have the correct setup. The arms appear well made with quality welds and good metal, but the overall design execution needs work.
