The other area of improvement comes in the form of larger inner bearings. How large? MASSIVE! The stock inner bearings are a mere 20x27x4mm. The oversized bearings used are gigantic 20x32x7mm bearings! That's 5mm larger on the diameter and 3mm on the width! The difference equates to a dynamic load rating that is nearly 300% higher than the stock bearings while the static load rating is over 300% higher! That's triple the strength of the stock inner bearings.
If you've ever blown a stock inner bearing or broken a stock front axle carrier, you need to check these out!
Tech Notes: RPM Oversized Front Axle Carriers replace stock Traxxas #7737. Each package is sold as a pair (one left and one right) and includes two inner oversized bearings (one for each side). Outer bearings are stock Traxxas bearings (#5106 or #5106A) and are not included in this kit.
