We now carry Heavy Duty Long Spline Drive lines to suit your single, dual, and triple case needs.

Our USA-made Heavy Duty Long Spline Drive lines feature a 10-spline 1-5/8" slip and is built with 0.156-inch thick USA steel tube!

Available with or without a CV Joint, they feature full length splines for maximum extension and versatility to fit your custom high strength drive line needs. The longer the drive line, the longer the splines.

We perform custom grinding modifications to our CV Jointed versions, increasing the droop angle by up to 65%!

Made to order. Please specify a length before adding to cart. To get the correct length drive line for your application, please measure the distance from your transfer case flange down to your differential flange, making sure that you measure from the same radial position. In other words, if you imagine each flange as the face of a clock, make sure that you measure from 3-o'clock on one flange to 3-o'clock on your other flange. Also, please ensure your truck is resting on level ground at normal load and that the tires are equal in diameter and air pressure. Remember that any off balance or additional load in your cargo area(s) may affect your measurement. Drive line comes "true" & is not balanced. Balancing is available by request. High speed use will result in a vibration which can not be balanced. We do not recommend these for rear applications. Please call for more info.

These drive lines will get your project finished and get you out on the trails where you belong!
