This heavy-duty axle bearing carrier is a direct replacement for Honda TRX 250R and 400EX ATVs from 1986 up to 2014. It's machined from forged 6061 billet aluminum, which is stronger than many cheaper cast carriers. The bearings and seals come pre-installed, so installation is much faster – just swap out your old unit. Fits part number 42500-HN1-A40. A must-have if your carrier is worn, cracked, or the bearings are shot. Makes a noticeable difference in rear wheel stability and smoothness. Always confirm your ATV model and year before ordering, and consider using a mechanic if you're not comfortable with suspension work.
