Your 1999-04 Mustang was built using rubber bushings in the control arms. Urethane control arm bushings deflect less for better handling and straight-line traction. Complete sets include bushings for upper and lower arms unless otherwise noted. Original bushing shells must be re-used unless otherwise noted.
Lifted or lowered suspensions, increases in horsepower, plus-size wheels and tires can subject traditional rubber suspension bushings to forces beyond their limits. Control arms, strut arms, leaf springs, body mounts, motor mounts, transmission mounts, sway bars and shocks all control movement and maintain alignment but the rubber bushings they use are designed for more "middle of the road" use. Rubber also deteriorates over time, further reducing control. This contributes to premature component failure, a "spongy" ride and less than ideal performance handling. Urethane bushings can correct these conditions, and improve drivability in your Mustang or Ford Lightning.
Just a quick note to say what great people (Eddie Davis) are at Latemodel Restoration. I ordered and bought a set of Track Pack Wheels for my 2014 Mustang GT.Their prices and service is the BEST in the MUSTANG INDUSTRY, not only the price and service but the honesty. The wheels came thru with the wrong center caps one call to Eddie Davis corrected the situation in one phone call and the next day I had the center caps (FORD RACING) the correct ones no BS, they just did the Right Thing,whereas in this Day and Age you don't here that often. LATEMODEL RESTORATION is the only place for your Mustangs parts and equipment, trust me try them and you will see what I mean!!
