Anyone have any experiences with this gear oil? I'm currently running RP 75w-140 and i've always been a fan of Red Line products. I figure the Heavy Shockproof will be good for how much load my gears see. This will be going into the front and rear differentials of a supercharged 5.3L Silverado cammed with 35" tires and 4.56 gears ~450RWHP

we use it in the 3000GT VR4, works well FWIW.
Amsoil severe gear is my current favorite, and Im running it in all of our cars.

It seemed to do well in a 2000 S2000 diff (Torsen LSD). I would stay away from the RL 75W90 though. I've never seen an acceptable UOA for that product yet. Here's a comparison link I posted about a year ago. There's a HD Shockproof UOA somewhere in the thread.

Call Redline for info.
Isn't this stuff supposed to be equivalent to a 250 weight? 
I usually recommend this to people as a last resort if everything else whines or leaks. One person had a Land Rover overdrive unit that was so loud, he would drive with earplugs. He had been using a 50/50 mix of 75W-140 gear oil and Lucas Heavy-Duty Stabilizer when I recommended he look at Red Line Heavy Shockproof.
I don't know if he ever took my advice.

From the Red Line website:
"A unique lubricant containing a suspension of solid microscopic particles as an extreme pressure agent--unique solid dispersion which cushions gear teeth to help prevent tooth breakage and allows the use of lower viscosities.
Recommended for heavily-loaded racing differentials and transmissions, Off Road racing and problem gearboxes. The viscosity characteristics allow the lubricant to resist throwoff and provide a film thickness similar to a 75W250 grade, while providing the same low fluid friction as an SAE 75W90."
So if it provides the film thickness and protection of a 75w250 but flows like a 75w90 (could produce better MPG) i don't see the down side
