Necessary to adjust camber on cars that have been lowered or are competition driven, the STILLEN built Adjustable Upper Arms allow you plus or minus 3 degrees of precise adjustment.
The unique rack and pinion design allows for a quick change in setup. Adjusting your car's suspension with more negative camber will increase the vehicle's cornering ability as the tire is able to maintain a wider patch (contact area) through the turns.
Urethane bushings have been designed to retain lubricant for quiet operation and re-lubing is easy with the built in Zerk fittings.
A four wheel alignment is recommended.
