Detroit Speed's X-Gen series of front suspension systems allow you to integrate Detroit Speed suspension technology into any vehicle. This complete suspension module is available with a 59.5" track width and is ready to be subbed into your application with the 2" x 4" rail sections. These are the same suspension systems found in Detroit Speed's bolt-in front frames so they have been designed, engineered, and developed to provide the ultimate in performance on both the road and the track. Base Shock: The DSE/JRi 'Detroit Tuned' base shock is a 'pure blood pedigree' racing shock in its most efficient form as a non-adjustable unit. Although non-adjustable, it shares all the increased dynamic responses of all the JRi adjustable models while providing excellent ride quality on the street.
