Tekno RC TKRBB15214 Ball Bearing (15x21x4, 4pieces) EB48.4 NB48.4

Tekno RC TKRBB15214 – Ball Bearing, 15x21x4mm (4-Pack, EB48.4/NB48.4)

Product Description:
The TKRBB15214 is a set of four 15x21x4mm ball bearings for the redesigned .4 CVA driveshafts on the EB48.4 and NB48.4. The .4 CVAs use an oversized ball joint to reduce wear and improve consistency — on smoother tracks they typically deliver faster corner speeds, quicker acceleration, and less weight transfer than the stock UNI driveshafts, letting you get on the throttle earlier in the corner.

Features:

• 15x21x4mm precision ball bearings
• Matched specifically to the redesigned .4 CVA oversized ball joint
• Improves consistency and reduces wear versus the stock UNI setup
• Must be used as part of a complete .4 CVA set

Requires: Use alongside the other .4 CVA parts — Driveshafts (TKR8072), Stub Axles (TKR8070), and CV Rebuild Kit (TKR8073)

Includes: 4 ball bearings

Fits: Tekno RC EB48.4, NB48.4
