We now carry Heavy Duty Long Spline Drive Shafts to suit your dual case needs.
These drive shafts are only intended for Front-use in Dual Case rigs using industry standard 4", 5", and 6" Rock Crawling suspension lift kits.
Our USA-made Heavy Duty Long Spline drive shafts feature a 10-spline 1-5/8" slip and are 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.
|Spline Diameter||Wall Thickness|
|Marlin Crawler Heavy Duty||1.625"||0.156"|
|Percent Difference||25% larger!||160% thicker!|
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. Eight or 9 mm flange bolt applications (1979-83) will need to upgrade their pinion and t/case flanges to the 10mm (1984-1995) style. Drive line comes "trued" & is not balanced. Balancing is available by request, however, keep in mind that due to their heavy weight and long spline nature, it is very difficult to get these shafts fully balanced. We therefore do not recommend these for rear applications.
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, measure from 6-o'clock on one flange to 6-o'clock on your other flange. Also, please ensure your truck is resting on level ground at normal loaded weight, and that the tires are equal in diameter and air pressure. Any off balance or additional load in your cargo area(s) may affect your measurement.
These front drive lines will get your Dual Case project finished and get you out on the trails where you belong!
