bs903-013 87.5mm CVA Shaft

This product is a 87.5 mm CVA shaft designed as a replacement front or rear axle drive shaft for hobby RC cars and trucks that use BS903‑013 length CV drives. It transfers power from the differential out to the wheels while allowing for suspension travel and steering angles. The CVA (constant‑velocity axle) design helps maintain smooth power delivery through articulation without binding, improving traction and drivetrain reliability. When the original shaft bends, wears, or fails, this replacement restores proper drivetrain operation in compatible RC vehicles.

Features:

• 87.5 mm constant‑velocity (CVA) drive shaft

• Designed for front or rear power delivery in RC vehicles

• Improves smooth power transfer through suspension movement

• Durable construction for strength and wear resistance

• Replaces worn or bent stock CV drive shafts

• Fits Redcat Racing and other hobby models requiring BS903‑013 length

• Ideal spare or replacement part for maintenance and repair
