    I understand the 203 and how it originallty worked. i.e. the lock positions lock the differential within the t-case and split the power 50/50 front and rear. Mine has the part time kit, so when it is in 4lo and 4hi, is the diff also locked as it would be before the conversion? my guess is yes. if so, it would seem like the 203 would be a better choice for traction becuase of its differential and the 50/50 split front to rear. the 205, 208, etc. didi not have a diff did they???

    All part time cases ging a 50/50 split when in 4wd. THe 203 stock with open diffs could send ALL power to any wheel With some traction it does work well but once you loose traction it's all over.

    in hi loc or lo loc the drivline is locked, when you have it in just hi or lo then the differential unitin the tail of the 203 takes effect,

    loc positions meant for offroad only(some slippage under tires), no-loc positions meant for on-road dry conditions(no slippage under tires)

    Basically your 203 with the part-time kit will function just like the other cases such as the 208, 205, 241, etc....
