HRTRXM3701 Metal Center universal Driveshaft TRX4-M

A pair of hardened universal center driveshafts engineered to replace the stock plastic center shafts in 1/18 scale TRX‑4M crawlers. Precision machined steel and aluminum construction increases drivetrain strength and reduces the risk of breakage under load. Dual lengths accommodate both front and rear positions, yielding smoother power transfer through the transmission and axles.

• CNC hardened steel and aluminum bodies for durability and wear resistance
• two universal joint shafts included in different lengths for front and rear fitment
• smoother rotational movement with reduced drivetrain slop
• direct replacement for standard plastic center driveshafts
• improved torsional rigidity under torque loads
• black corrosion‑resistant finish for longevity
• supports consistent power transfer through suspension articulation
