JB Conversions NP241 Slip Yoke Eliminator kits

Realizing that our Doubler kit isn't the transfer case answer for all 4wd's, we've started carrying the JB Conversions slip yoke eliminator kit for the NP241.  The 241 evolved from the NP208 in 1989 and is still in use today.  It's a relatively durable chain drive case with a 2.7:1 planetary gear reduction and aluminum case.  While it's not super burly like the 205, the 241 is adequate for trail ride vehicles with 35-37" tires, depending on your specific vehicle, driving habits, etc.

The one really weak point of the NP241 is the slip yoke type rear output.  It increases the overall length of the case, eats seals, can contribute to driveline vibrations as the output bushing wears out, and if you have rear driveshaft damage, it can leak all your t-case fluid out on the trail.  The fix is the slip yoke eliminator or "SYE" kit. This kit provides a 32 spline fixed output that you can bolt any one of a number of yokes directly to.

The standard SYE kit reduces the overall length of the 241 by 5-6" and the new Super Short SYE kit reduces the length of the unit by 9" overall.  This puts the 241 in the same length catagory as a 205!  The 241 is now an attractive option for short wheelbase vehicles.

The standard 241 SYE kits work on any GM 241, either right or left hand front drive in GM or Dodge trucks except the Dodge HD version.
 
The super short SYE is only available for LH 241's, if you have a RH 241, you have to use the standard length kit.
Price for regular length: $340.00
Price for super short: $360.00

We also carry bearing and chain kits for the NP241 if you want to rebuild your transfer case while you have it apart.
