The first issue being durability. We designed these carriers to handle some serious abuse. RPM Oversized Axle Carriers are BEEFY with massive support ribs for the strongest possible carriers available.
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 we use 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! Our Oversized Front Axle Carriers are molded in black and backed by our limited lifetime breakage warranty. You can't go wrong with RPM parts on your X-Maxx.
Tech Notes: RPM Oversized Front Axle Carriers replace stock Traxxas TRA7737. 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 (TRA5106 or TRA5106A) and are not included in this kit.
