Yeah. I haven't seen actual proof that the starter, etc., is any different than before.
I found this about the system on the Cherokee:
A stronger, 220-amp alternator
An absorbent glass mat (AGM) high-durability battery
A modified starter with hardened gears, reinforced castings, higher-power motor, longer life brushes, and higher-precision bearings and shaft
A large Denso starter solenoid
A voltage stabilization module that prevent voltage dips during cranking, providing a buffer for the car computers and such
A Bosch battery sensor which predicts voltage and capacity, and measures alternator current and battery temperature
Special programming in the car computer
Apparently only the Grand Cherokee has a separate battery for the stop start system.
