when did powertrax become so expensive.

 

well, seems they used to be more affordable

 

the big savings comes in their quick and easy installation...they look to be about the same price as when i got mine

 

What's the story on these? How strong are they, how far have they been proven to?

 

I had one in my Cutlass (3800 lbs) that I raced weekly (big blocks, nitrous, superchargers and slicks). When I took it out after 8+ years, it looked brand new. I put it in a different cars and it is still going today. I like them and would buy again.

 

mines been doing great, although i'm not putting down any real power. it's definitely noticeable as you would expect from a locker. it installed extremely easy and it's a very positive 100% both wheel drive which are the two reasons i got it. i drive a two wheel drive truck in the winter here so both rear tires are very helpful and i don't have the time to pull the rear axle out of my truck to install something else...my dad put one in his '90 short bed with a strong 383 and a manual tranny and has had no issues with it either.
