VSC & A-Trac on pre 2009 TRD Prerunners? was that an option?

    i was reading some posts about the 2009+ tacomas that don't have a true LSD differential in the rear and made me think about it.

    when i bought the tacoma (2006 4-door TRD sport prerunner, new) i also had a lexus GX (basically a fancy 4runner) and it did have vsc and A-Track, but it was AWD and i am pretty certain it did not have true mechanical LSD differentials. ( do not remember if it had DAC or not)

    did they offer VSC or A-Trac on the older 2nd gen prerunner tacomas? or because of the mechanical LSD rear diff, it was not offered? i specifically told the dealership i wanted EVERY possible option for the prerunner, i even got the #2 package , the one that was like $3000 more with the extra oil and transmission oil coolers, bigger alternator, towing package, etc, not just the 'pretty' sport package with the color-matched grille, color-matched front/rear bumpers, color-matched door handles, color-matched mirrors, bilstein shocks/struts, TRD interior, hood with scoop, A/C inverter in the bed, stainless steel exhaust tip, 17" wheels, etc. was just curious because i'll be pretty pissed if it was available and they did not tell me

    A-trac is only available on 4wd TRD off-road models.

    The major difference between the sport and the off road that I think a lot of people over look is the brake system. Off roads have a hydroelectric brake booster, everything else has a vacuum brake booster. You can not get A-Trac or DAC without a hydroelectric booster. All GX's have a hydroelectric boost also btw.

    A-TRAC is a traction system that works in Low Range on the front and rear tires, thus only 4WDs, and no PreRunners.

    I heard it was a 'hydraulic' brake booster vs. the normal vacuum break booster. Not sure what hydroelectric is... unless it means the combining of electronic spin sensors and the hydraulic booster?

    Thank you.

    It's the same thing, just different terminology. The hydro one uses a electronic pump to boost brake fluid pressure and the vacuum one uses a normal vacuum booster.
