This is a pack of two optional ProTek R/C Titanium Rear Axles, intended for use with the Team Associated B5 and B5M 1/10 Scale 2WD Buggies. These are a replacement for Team Associated  HD Axle (ASC71019).

These titanium axles are CNC machined to near-exact tolerances from high-quality 6AL-4V (Grade 5) titanium alloy material and polished to a brilliant finish.

Weighing only 3.5 grams per axle, compared to 6.5 grams per steel axle, these titanium axles drop a combined 6 grams of rotating mass from the drive line. For the stock racer, these axles help decrease motor fatigue, boost efficiency and reduce overall weight.

Why Titanium?
Titanium is strong, dense and super lightweight. In fact, Titanium has one of the highest strength-to-density ratios of all the metal compounds, making it the best advantage for dropping weight without sacrificing strength or durability.

6AL-4V Grade 5
6AL-4V, or more commonly known as Grade 5, is a Titanium alloy mixture composed of 6% aluminum and 4% vanadium. It is significantly stronger than pure titanium but more expensive to manufacture. Grade 5 is the most widely used titanium alloy for its excellent combination of low weight, high strength and corrosion resistance.
