Axial Racing Yeti XL Steel #45 Rear Shaft YTL237S by GPM  [YTL237S]

Overview of the rear drive shaft

This steel #45 rear drive shaft is supplied as a replacement component for Axial Racing Yeti XL vehicles. It functions as a direct-fit rear drivetrain part designed to restore drivetrain geometry and deliver torque from the gearbox to the rear wheels. The item is sold as 1 pcs and is appropriate for scheduled maintenance or upgrading worn factory shafts.

Fitment guidance: the shaft installs into the rear output and requires normal removal of the rear gearbox and associated suspension links. Verify splines and retaining hardware taken from the original assembly, clean the mating surfaces, and inspect 走珠軸承 and seals while reassembling. Use official service instructions for torque and reassembly order; no modifications are normally necessary when fitting to Yeti XL rear assemblies with the same shaft profile.

Setup impact: installing a steel #45 shaft brings greater stiffness and improved resistance to bending versus softer materials, which can reduce drivetrain lash and improve durability under higher loads from upscaled motors or revised gearing. Confirm rear axle alignment and avoid excessive screw torque to limit bearing preload.

Choose this shaft when replacing worn rear drives on Axial Yeti XL builds or when you need to recover original drivetrain stiffness during tuning.
