The stock center diff is the weak link if the car is launched hard or has a lot of torque. Our 4-spider unit will make the tranny capable of withstanding 600hp or more without risk of breaking the center diff spider gears. We also install an upper Torrington bearing. All center diffs are machined by us in house using the milling machine seen in previous pictures. On the right is a stock 2-spider and the unit on the left is a 4-spider:
