In 1992, JR Race Car began manufacturing parts for the newly accepted NHRA Junior Drag Racing. JR Race Car initially offered components such as turn key Jr dragster chassis, engines, clutches and chassis components (manufactured in house from the beginning!). Over twenty years in Jr Drag Racing, JR Race Car has led the way in Jr Dragster manufacturing from initially machining a large portion of the CNC parts for other vendors in the market, to designing and machining its own ZR, Titan, and ZR-4 Engines and revolutionizing the market with the Shockwave and Shockwave OD CVT (centrifugally variable transmission) clutches and the innovative Hercules Chassis. JR Race Car is the only place to go for NHRA, IHRA, and ADRL Jr drag racing components.
