Was just looking around for a set of true tracs and came across this:

It looks like you can use it on two differentials, so $50 for the front diff and $60 for the rear diff. Just be careful though, you need to spend at least $400 for the $50 off and I have seen the front tru trac for less than $400($385 at amazon).

Perfect timing. I'm ordering a set this week. Thank you!

I really want to order them, but my conscience is telling my student loans and mortgages are a wiser investment
