Overview
This hardened steel diff coupler is the front and rear differential coupler replacement for all versions of the Tekno EB48, NB48, ET48 and NT48. It is the part that transfers drive from the center driveshafts into the front and rear differentials, so it lives in one of the hardest-working spots in the drivetrain.
The same coupler is used on the Tekno RC V4 kits. It installs on the rear diff and accepts the Tekno RC V4 drive axles (dog bones), making it the right piece for both replacement and V4 drivetrain builds.
Key Features
- Hardened steel construction for long service life
- Direct front and rear differential coupler replacement
- Fits all versions of the EB48, NB48, ET48 and NT48
- Also used on Tekno RC V4 kits
- Accepts Tekno RC V4 drive axles (dog bones) when installed on the rear diff
Performance Benefits
- Hardening resists the rounding and wear that cause drivetrain slop
- Tight coupler fit keeps power delivery crisp and predictable
- Steel holds up to the shock loads of hard launches and landings
- Restoring a worn coupler reduces noise and protects surrounding diff parts
Usage Notes
- Replace couplers once the drive pin pockets show visible rounding or play
- Keep the coupler and axle ends greased to slow wear
- Inspect at the same intervals you service your differentials
- Confirm which axle style your build uses before mixing V4 and earlier parts
