GPM Racing #45 Hardened Steel CVD for Front / Rear - 4pcs Set for Traxxas 1/10 E-REVO VXL (ER2123F/RS)

Technical briefing ER2123F/RS CVD dogbones

The ER2123F/RS kit provides a 4pcs CVD dogbone set intended as direct front and rear replacements for TRAXXAS E-REVO VXL applications. These aftermarket components are focused on increasing drivetrain longevity and maintaining consistent wheel rotation under high load conditions.

Material and sizing: components are made from hardened steel #45 and conform to the supplied dimensions: a 123mm dogbone length with the shaft diameter increased from 5.5mm to 6.5mm to deliver a stiffer connection between gearbox output and wheel hubs. The dimensional change reduces bending and wear while imposing only a modest mass increase.

Installation and tuning considerations: install where the vehicle uses stock-style outputs sized for 6.5mm dogbones and verify spline engagement and drive angle clearance. Expect reduced driveline compliance which can affect handling feel; validate toe and suspension droop after fitting to retain predictable steering response.

Packing includes

• CVD – 2pcs
• Set Screws 4×5 – 2pcs

Specifications

• Item: CVD dogbone set 4pcs (front/rear)
• Material: Hardened steel #45
• Model Number: ER2123F/RS
• Compatibility: TRAXXAS E-REVO VXL
• Dogbone Length: 123mm
• Dogbone Diameter: 6.5mm (upgraded from 5.5mm)

Use ER2123F/RS when a hardened steel replacement is required to restore or increase driveline durability on TRAXXAS E-REVO VXL models while maintaining stock front and rear interfaces.

What tolerances should be checked on fitment?

Verify spline engagement depth, hub bore clearance for a 6.5mm shaft, and axial play after installation to ensure secure connection and prevent premature wear.

Is any additional hardware required?

The packing list supplies the basic set screws shown; if your setup uses different retention hardware, source equivalent fasteners rated for driveline use.

How does the diameter change affect loads?

Increasing shaft diameter from 5.5mm to 6.5mm reduces section bending stress under torsion and shock loads, improving durability at the expense of a small mass increase.

Recommended post-fit checks?

After fitting, torque set screws to spec, run suspension through travel to confirm no interference, and perform a short test at low speed to inspect for abnormal noise or play. Write Product Review Please sign in your account before you can write any review. Sign In Close
