Measuring Your Jeep Wrangler JL Front and Rear Shafts
Jeep JL Drive Shafts
We build a 1350 series drive shaft for the front and rear of the JL Jeeps. After careful consideration of things like horsepower, vehicle weight, available torque due to gearing, and just where the sport is headed, we have decided not to offer a 1310 series shaft for the JL. We don't believe it is safe and we'd rather lose a sale than sell something with which we are not confident. Because of this, 1350 series is our standard shaft for the JL and JT. 1410 will soon be an option for the rear shaft. Due to the many options available on the JL we do require length measurements in order to build the drive shaft. The measurement can be taken with or without the stock shaft still installed.
If you have replaced the stock transfer case or axles please give us a call and we can guide you through the measurements and dimensions you will need to provide in order for us to build you a drive shaft.
Rear shafts. We are currently unable to build rear shafts for JL models with a Dana 35 rear differential.
Measurement is best taken with the vehicle parked on flat ground at normal ride height. Measure from approximately center height (the 3 or 9 o’clock position) for the best measurement. If you have a lift installed on the vehicle, you may need something to rotate the differential for the CV type drive shaft to function properly. This is typically done with adjustable control arms.
Pinion should be 1 – 3 degrees lower than the slope of the drive shaft.
Our drive shaft package replaces the rear output flange to a C.V. (Double Cardan) compatible flange for the t-case, and replaces the stock pinion flange with an aftermarket yoke.
The above drive shaft is the 1350 series. Cost is $759.00 plus the $10.00 processing and packaging fee.
We use our Gold Seal U-Joints standard. Spicer Greaseable (with the grease fitting in the body of the cross) or Non Greaseable U-Joints can be installed if preferred with no additional charge.

Length measurements need to be taken the same way as stated above for the rear shaft.
