Super flexible suspension systems require more slip spline than the stock driveshaft is able to provide. The result with a stock slip spline, is the driveshaft pulls apart on the trail. This long spline kit is designed to replace the stock slip section and provide more than twice the slip length of stock.
To install this kit.... the stock slip section and tubing, is cut off and replaced with our long spline section and new tubing.
This driveshaft kit is stronger than stock. Testing shows that a stock driveshaft will twist off and fail after a maximum load of 3,900 ft/lbs of torque is applied. This shaft kit tests to a maximum of 4800 ft/lbs or torque. This is accomplished in two ways; first the size of the material is increased, both on the inside and the outside of the slider section. Then the material is specially heat-treated to increase its strength.
Kit comes with a Heavy Duty U-Joint installed and tack welded in place to ensure it does not come out on the trail.
This product is a heavy duty replacement part and is not recommended for applications requiring a balanced driveshaft.
Not recommended for use on the street.
