Tamiya 22106 OP. 2106 2WD ONE-PIECE STEEL FRONT AXLE & HUB

OP. 2106 是田宮 Hop Up Options 系列的 2WD 越野車升級零件，專為提升 RC 車輛性能與設定調校而生。這款前輪輪軸以高強度的鋼材製成，並將六角型輪轂與輪軸一體成型，大幅精簡零件數量，也使拆裝與保養更為便利。它可作為 DN-01 SR 底盤套件的備用零件，亦適用於 M-08 / M-07 底盤的非驅動輪，是強化越野車行走系統穩定性的基礎之選。

選用鋼製的輪軸，可提升前輪組的剛性與耐用度，即使面對越野路面反覆衝擊也能保持穩定作動；搭配一體式結構，裝卸輪轂時無需逐件對位，整備手感俐落。無論是想為 DN-01 SR 多準備一套備件，或是替 M 系列底盤升級非驅動輪軸，這都是簡單而實惠的第一步。

OP. 2106 is an upgrade part from the Tamiya Hop Up Options series, developed to enhance the performance and tuning of 2WD off-road vehicles. This front wheel axle is machined from high-strength steel, with the hexagonal wheel hub and axle formed as a single unit to reduce the number of parts and make disassembly and maintenance easier. It can serve as a spare part for the DN-01 SR chassis kit, and is also compatible with the non-driven wheels of the M-08 / M-07 chassis — a solid, straightforward first step toward a more stable off-road running gear.

Choosing a steel axle boosts the rigidity and durability of the front wheel assembly, keeping operation steady even under repeated impacts on rough terrain. Thanks to the one-piece design, the hub can be fitted and removed without aligning multiple components, making maintenance quick and clean. Whether you are stocking a spare set for the DN-01 SR or upgrading the non-driven axles on an M-series chassis, this is a simple and cost-effective choice.
