Just wondering if anyone is using Redline synthetics in their diffs? It's time to change out the junk in mine, and I'm wondering if I should use their regular 75-90 or the Extra Heavy Shockproof, which supposedly has the viscosity of a 75-90 but the protection of a 75-250.
I've been using the Extra Heavy Shockproof in my Harley's transmission with excellent results, but...
any ideas?
