JR Race Car clutch rollers are available to maintain the performance of your Shockwave clutch. They offer roller bearings, roller bushings, and Helix rollers. Choose the roller options to best service your Jr. Dragster. Clutch roller options: * Roller bearings aka Big Black rollers, outer rollers, or plastic rollers are the torque transferring components of your clutch system, also one of the only common components between the Standard and the Overdrive Shockwaves. Kits include roller assemblies with bearings, washers, and nylock jam nuts. * Roller bushings aka steel rollers or flyweight rollers take all the force from the flyweights. One of the most durable components in the system, these are the most neglected components in the clutch. Kits include rollers with bushings, dowel pins, and button head cap screws. * Helix roller aka driven rollers or cam followers guide the Helix on the fixed sheave smoothly with as little wear as possible and provide a huge step in consistency and life. Available individually, they are pressed into the reverse driven clutch and often require a small rubber mallet to remove them.

Z Automotive TranZformer electronic shift kits transform your car into a neck-snapping, tire-chirping fun to drive beast that at the press of a button, returns to stock. Best of all, they're completely hidden. Available in Gen 1 or Gen 2 kits, you can have your NAG1 transmission shift how YOU want it to. You get to modify shift firmness to fit your driving style/mood, plus a lot more. They install in minutes, connecting via wiretaps into wires hidden behind the steering column lower cover. Once installed, TranZformer kits will modify transmission parameters for that real "old school" muscle car shift feel. Chirp through gear shifts or just firm them up a little for towing or for track use; use your steering wheel buttons and EVIC screen (or cruise stalk/buttons for those without EVIC) to adjust shift firmness on-the-fly, whenever you want; connect to your PC via USB cable to dial-in independent upshift and downshift boost percentages (0 to 100) for each gear in both Drive and AutoStick mode. You can reduce the time delay when shifting into Reverse and Drive, adjust shift firmness scaling based on throttle position, and reset or kill the TCM's adaptive learning system, keeping the TCM from dialing back the shift firmness over time. Select the kit designed for your vehicle. Some of the features and benefits (may vary by kit): * Z Automotive Programming Utility (for Windows PCs only) allows you to program shift parameters, view status, update the firmware, and more * Steering wheel shifting (SWS) allows you to use your steering wheel's buttons to manually control gear shift while keeping your hands on the wheel * AutoUpshift allows you to set your own shift points when in AutoStick * Line Lock mode holds the vehicle with the front brakes so you can hit the gas and do a perfect burnout Peak rpm display: Will display actual shift rpms after each shift--great when adjusting auto upshift to squeeze every last bit out of that high revving cam, or to check what rpm you hit when shifting manually * 0 to 30 and 0 to 60 timer Reset adaptives: Will reset TCM adaptives any time you wish
