k all i am going to upgrade the hydraulics in my 98 z28 when i install my z06 clutch. now what i am wanting to know is there any difference in the ls1speed upgraded hydraulics kit listed at 279.99 and the parts from gmpartsdirect p# 15046288(slave) and p# 12570277 (master). It seems to me they include the same things and i could save like75 bux (approx) on the gmpartsdirect deal buying them separatly. Thanks for dealing with the newb.

 

15046288 is the part number for the '98-'00 slave.

12565145 is for the '01-'02 slave.

Recently GM has discontinued #12565145 and is now offering #15046288 as the only slave for the '98-'02s (read: all). I don't know if GM "upgraded" the old slave or not or if they just wanted to switch back to the '98-'00 slave...I have no idea .

If I where you, I'd make sure that #15046288 has been "upgraded" or I'd buy #12565145. Some places might still have #12565145 but you won't find it at any GM dealership or GM parts retailer...15046288 is the only slave that they have listed now.


Just FYI

 

oh thanks for the heads up
