VSC, ALSD and TRAC use the brakes for controlling wheel spin. You don't have to do anything special when installing front and rear lockers. The systems will continue to work after installation. You can pull the plug on the master cylinder to disable VSC. Personally I would leave it working and turn it off when you need it off.

Seriously... The Tacomas are awesome in wet weather even in 2WD with VSC and TRAC... No more spinning out of the back end when cornering with an empty bed, and the TRAC in H4 is a big traction boost over open differentials (at least it is with the Off Road TRD's hydraulic brake booster)...

Now, by adding front and rear lockers, you have a near-ultimate off road Tacoma with a Sport body... Only thing really left to do besides good tires is to swap out the scooped hood with a high visibility hood for the steep grades you can climb with those lockers!

Have a great time, post photos!!

thanks for the info

I love my truck, however the only problem i have is with its 6" lift, 35" tires, when ever i corner the vsc kicks in, pumps the brakes, makes the sound under the hood, and cuts the power. it wouldnt be bad if it was happening if i corner too fast, but it does it when im cornering normally. i took it to the dealer twice and didnt get any improvement. it kinda made me mad cause i bought the vehicle brand new with the 6" lift and 35" tires installed.
you guys have any ideas?
thanks

You may want to try resetting the system as outlined in this post. Be sure to read Crom's posts: #2 and #12. Or, you might have success asking the dealer to perform the reset.

I wonder how the front axle shafts will hold up to 35s and a locker.

Should be ok... The weak link is either the R&P if stock or the CV axles. A good point was made to me that if you have a weak point it would be better for it to be the CV axles because of the ease of trail replacement over other possible parts that could break.

No. Its not. The hood sticks up about 2", if that. It does block about 1" of vision from the right side of your view, but I have yet to hear of it causing anyone to roll off a cliff, or wildly careening into other vehicles.

Simple... the OP seems to want an ultimate off road truck, but bought a Sport... so he has to add front and rear lockers... that means only two items are left to address to = an Off Road TRD... the tires and the hood. No insult intended, just the facts. Honestly, the tires on the Off Road aren't a whole lot better than the street tires on the Sport.

Sure, you can drive a scoop hood truck anywhere... it is just nice to have as much visibility as possible, that is all.

When I four wheeled with HB Murphy in Baja, he had me laughing when he said not only where the Sport hoods bad, but the Off Road hoods would be better if he could flip his around so it would be even lower! Too cool!

The TRD offroad is not the ultimate offroad machine to begin with. The OP's sport is now more capable than the offroad because of the lockers even with the scoop. But in the end who cares?

Anyway lockers and VSC...

Christian, I never said the Off Road was the ultimate... re-read... I said the guy with the Sport wants the ultimate... so he is getting lockers.

For those who want to get a factory equippped truck with the most traction, then that would be the Off Road 4WD... isn't that what you have? Do you ever use it? How about some photos? The others, you need to chill and stop being so angry that you don't have it! I am happy with my Toyota... VERY HAPPY!

If you have lockers, and they are turned on, you won't have one tire per axle slipping... so the limited slip system would never activate with the lockers on... seems simple logic to me... Nothing to turn off first. TRAC/ VSC/ A-TRAC uses spin sensors at each wheel... no spin, then no activation.
