thermal actuator bypass
Has anyone used this system from 4x4 posi lock.?
Would this be better then the cable bypass?
Part No. 1000: Perm-Lok The Perm-Lok permanently engages the Central Axle Disconnect (CAD) system and couples both front axles. Once installed, the front axles will not pull until the transfer case is engaged.
Ideal for:
Fleet operators
Emergency vehicles
Installation is easy and can be completed in approximately 10 minutes.

Suburban 8Lug Note: With Thermal Linear Actuator (TLA)

so this is what? a welded diff for the front that only works when you are in 4WD BUT not at all if you have Control-Trac 4WD?
never seen anything like this before. I'm interested if anyone has used this or knows more about it.

Just get the updated electric motor driven actuator for the front diff and forget about it.
That thing will work, but will make your fuel mileage suffer because it keeps the front axle locked in at all times.

so ur saying instead of having to wait when i engage my 4x4 it to lock in. when i move the lever to 4x4 its right on. no waiting of cable lever to pull or mess with.and no waiting for actuator to hopefully work.
i would think if u have control trac is would still work cause tht be same thing as 4x4 lever almost. it b same principle just control trac auto engages 4x4 instead of having to manually doing it as i do the lever. so as soon as it engages 4x4 youre front is locked in.

Do not confuse the control system used on the s-series with that used on the fullsize trucks. While the axle engagement is similar, the method used is quite different. There is no cable in the fullsize front axle engagement mechanism. No vacuum control either. It is electronic and that is regardless of whether the NP241 (NV241), NP243(NV243), or NP246(NV246) transfer case is used.
With that said, there is an inherent weakness with the originally supplied thermal actuator. GM revised the design to be an electric motor which engages soundly and quickly while still providing for the benefit of less rotating mass when disengaged. That gets my vote over something that permanently engages the front diff.
Do whatever it is that you want, but you came here asking for advice...

yes i understand that but pirate 4x4 also has a cable operated system instead of the actuator and that is what i was mentoning in my response. don't get me wrong i respect you're response and didn't mean for u to take it the wrong way. i just wanted some feed back on it and if anyone has had any expereince with tht. as far as the electric motor i know abt it and tht is like 120 and the replacment harness is another 60
