GPM Racing 4140 Carbon Steel Front Driveshafts and Drive Cups for Traxxas Mini XRT VXL 3S-108076-1 (XRTM062FS)

Technical front driveline upgrade

This aftermarket assembly replaces the front CVD driveshafts on the TRAXXAS MINI XRT VXL 3S chassis. The components are CNC-oriented 4140 carbon steel with a hardened black treatment and a CVD-style joint to allow increased steering angle while maintaining efficient torque transfer from the motor to the drivetrain. Each shaft measures 62mm from dog bone end to midpoint for the designated front CVD location on this model.

Units are supplied pre-assembled for quick installation. Drive cups and the specified set screws are included to complete the front assembly. For reliable fastener retention apply medium-strength screw thread adhesive to the set screws and verify torque values during initial break-in.

Packing includes

• Front Driveshafts - 2 pcs
• Drive cups - 2 pcs
• Set Screws M4x2.5x12.5 - 2 pcs

This precision replacement set focuses on strengthening the front driveline using hardened 4140 material and a CVD-style interface to support increased steering lock and consistent torque transmission; follow recommended thread-lock procedures and verify fitment with existing front CVD components before extended use.

What is the exact shaft length and fitment point?

Each shaft measures 62mm from dog bone end to midpoint and is intended for the front CVD mounting position on the MINI XRT VXL 3S; confirm against your chassis geometry before final assembly.

Why choose hardened 4140 carbon steel?

Hardened 4140 offers superior tensile strength and resistance to wear compared with softer steels, improving durability under high torque and reducing deformation in aggressive driving conditions.

Are the parts supplied assembled for rapid replacement?

Yes, the assembly is supplied pre-assembled; verify set screw torque and use a medium-strength thread adhesive to ensure retention during initial break-in.

What inspection routine is recommended?

Inspect the CVD joint for play, check set screw torque after the first run, and look for surface wear at contact points; address any looseness immediately.

Can these improve steering angle without body modification?

The CVD-style interface allows increased steering lock compared with some stock arrangements, but final clearance depends on wheel, tyre, and body choices and should be checked prior to aggressive use. Write Product Review Please sign in your account before you can write any review. Sign In Close
