Assuming you mean NV241OR (Rubicon 4:1 t-case), the 241 doesn't have a slip yoke to eliminate. it uses a fixed flange output.

if you have a 97-02, the swap is more difficult and requires modifying the t-case skid and tranny mount. if you have a 03-06, the swap is easier. you need to order a GM sensor and pigtail to make the 4wd light work. the t-case shifter linkage is completely different, so you either need to modify your existing linkage, get a Rubicon linkage or buy an aftermarket linkage kit. the speedo is a tone ring, so you need an electronic correction method to calibrate the speedo for tire size and gears. the front output yoke is a 1330, so you need to buy a 1310 yoke to use your old driveshaft. in the rear you need custom built shaft to adapt to the 1310 yoke on your diff. the 241OR typically goes for around $1200-1500, and the parts described above will put you close to $1800-2000.

if you're refering to another 241, like the NP241C from a Chevy or Dodge, then no it will not work. the outputs are far too long and the spline shafts would need to be swapped out. its easier to make a NP231HD out of your existing t-case...which uses Chevy 241C and/or Dodge NP231HD parts.
