Our Exclusive H.D. Single Chain

Replace the weaker stock dual chain set-up from factory with our heavy duty single chain proven to be 60% stronger! The original dual chain assembly was used to help eliminate noise that can be caused by the chain. However, if you do choose to use the factory dual chain, be aware there are 2 major weak points in the assembly. With the stock dual chain, there is a link in each chain that holds both ends together, forming a loop. These links are set opposite of each other which creates pressure points when placed under stressful conditions. By upgrading to our single chain you have not only eliminated these pressure points but now have a chain that is much thicker than stock. Noise levels are still kept to a minimum. Our H.D. Single Chain comes complete with your choice of 2.93 (factory), 3.29, or 3.69 gear ratios to meet your high performance needs.

Contact us as to which gear ratio would work best with your modifications.

High Stall 245mm Torque Converter & Flexplate (Flywheel) Combo:

The improved 245 mm torque converter boasts a realistic stall speed of 2200 RPM. Greatly improving launches and ¼ mile times. Combine it with our OEM style balanced flexplate and you have all you need to keep your wheels spinnin’ on the street or strip. Smaller than the factory L67 TC and weighing about 7 lbs less, the torque is sent directly through your transmission to the wheels. If you can’t see better times with this, hang up your driving gloves.

High Torque Input Shaft

After replacing several factory input shafts (for ourselves and for our customers), we decided to make our own. The C-Ya Racing High Torque Input Shaft has been manufactured, tempered and splined to make sure that it can take whatever you throw at it. It replaces the factory input shaft and reduces the amount of slop that frequently occurs between the input shaft and drive gear. Our input shaft also comes complete with a new oil diverter tube and three brand new O-rings installed using the proper J-Tool.

C-YA Racing Limited Slip Differential

The C-YA Racing Limited Slip Differential gets both wheels going together and in sync! This LSD provides more control in everyday street driving conditions and especially at the strip by virtually eliminating torque-steer, improving launch and ETA times and virtually eliminating excess wear on the differential caused by doing "one-wheel" burnouts. When you buy it with our Race Transmission and save $50!
