Possible to retrofit Stabilitrak into 04 Avalanche?

Wondering if anyone knows how difficult it would be to retrofit Stabilitrak into an 04 Avalanche?

What would it entail? Just the PCM, on/off button, anything else? Anything at the actual brakes?

Would it be worth it? Does anyone feel it’s not necessary or just a gimmick?
 
why???

I doubt it would be easy since you donot know what all sensors and computers and output devices (tranny brakes engine are controlled and what happens.

IT is not a Gimmick but designed to keep all 4 wheels on road, oversteer and help prevent flip over.


IF you want it buy truck with it.
 
I understand that Stabilitrak activates brakes individually to do its thing, so will it be affected if I upgrade to bigger brake calipers/rotors?

No, but trying to put stabltrac on a truck that didn't come with it would require a different rear end since it uses sensors at each wheel instead of the one in the transfer case(Or modifying yours to accept them). Would also potentially need a different ABS unit, plus the control module and all associated sensors it may have (They may be internal) Lots of wiring for everything, reprogramming of affected modules including the ABS, ECM, Transmission control unit and who knows what else. And unless you know someone that can do this, it can be very difficult to find someone that can reprogram everything. And if something isn't done 100% right, you can severly damage your brake system. Such as have them not apply at all when you need them too and smash into someone. Would be potentially far more complex than doing an LS Swap into an older truck.
 
Bottom line is it would be a nightmare and never work right. Ton of electronics and sensors etc.

YGMN is correct, way to solve that issue is buy a truck that came with it.
