Got a race car or performance car with a manual transmission? If so, then you know how important it is to have a clutch that’s durable enough to be up to the task. JR’s Shockwave line of clutches are some of the best clutches available today, designed to stand up to the roughest conditions, with simplicity and consistency in mind. This is your destination to not only find JR Shockwave clutches, but also specialty tools needed for clutch installation, adjustment and repair. 

Performance Benefits & Key Features

Higher torque engines put a lot of demands on the clutch and the entire drivetrain, and Shockwave clutches and components are designed for extra clamping force. The Shockwave features a square main shaft rather than a conventional round shaft, with ball bearings to transfer torque instead of a slide bushing. For clutch installation, repair and maintenance, this is where you can find parts like a 22 through 44 gram flyweight kit (for overdrive clutches), overdrive springs, reverse driven helix (32 through 46 degree), drive belts, sheave housing assemblies, spider assemblies for overdrive Shockwave clutch, dual bearing supports, ¾” reamer tool, belt alignment tool and OD removal tool. 

Fitment, Compatibility & Applications 

JR Race Car Shockwave clutch components are bolt-on performance for a wide range of vehicles. The 7” reverse driven overdrive effectively gives your car a lower 1st gear ratio than other driven units, equating to a one-sprocket size difference. It’s a proven performance item, with most drivers reporting a full 2/10 of a second gain in ET with this component. Spiders are constructed from billet aluminum with roller bearings and bushings. Upgrading to a Shockwave clutch is a great way to ensure more consistent performance and a more robust and bulletproof drivetrain for your street or strip car. As always, be sure of your vehicle’s year/make/model, trim level and engine size when ordering, to make sure you’re getting the parts you need.
