High Temperatures Suck.

You know it, we know it, your wheel bearings live it.

If you look through our postings over the years, you'll see that one of the things we've been trying to do for you guys is to come up with something that can make your wheel bearings last longer. The big thing to combat is heat. Heat is the bearing killer. Anything you can do to keep heat out of the wheel bearings is going to make them last longer. The problem is that you've got the amazing source of heat called "your brakes" with a direct metal-to-metal contact to your hub and then your bearings. Even worse, it's iron-to-steel, making it a 12-lane heat superhighway. So we thought we'd through up some construction barrels.

Titanium is a metal, sure, but it's a metal that hates heat. Heat stole Titanium's woman a few years ago and Titanium hasn't moved on. Titanium expresses this hate by having a low (for a metal) thermal conductivity. Grade 5 Titanium, the one we're using, has the lowest thermal conductivity of any Titanium alloy you can buy without a defense contract paying for it. Grade 5 Ti has a thermal conductivity of 6.7 W/m*K. Compare that to an average alloy of steel at nearly 50 W/m*K or 6061 Aluminum, who's a total heat whore, at 167 W/m*K. Don't worry about the units, just focus on how big the numbers are compared to Grade 5 Ti. This is the same Titanium we're using in our brake pad shims (same idea is this, just between the brake pad and the piston, rather than the rotor and hub).

So, here's what you get with these:

• Two Titanium bearing shields
• Four spacers for the caliper

Install is really simple:

• Remove wheel
• Remove caliper or bracket that holds the pads from the knuckle (or upright)
• Remove rotor
• Make sure surfaces are clean and free of defects
• Install sheild
• Put rotor back on
• Install caliper or bracket back onto the upright, BUT make sure the spacers go between the caliper or bracket and the knuckle. This will move the caliper assembly out one material thickness. This is needed because you just moved the rotor out one material thickness.
• Put everything else back together.
