H&R Street Performance Coil Overs are the perfect suspension solution for discerning drivers - from daily drivers to serious tuners—who can appreciate the awesome handling and superb ride comfort. Each coil over shock is custom valved to work in conjunction with a precision-engineered progressive rate spring, creating a finely tuned suspension system. The fully threaded shock body allows for adjustable vehicle height. This feature helps balance vehicle weight, resulting in a lower center of gravity and improved performance and control. 

• Height adjustable to 1.0 - 2.5" on average
• Fine tune lowering to what you want

Note: Ultra Performance are Street Performance Coil Overs with higher performance springs and shocks that are tuned for the more sporty driver. Their performance level is a step between the Street Performance and RSS Coil Overs.
