This aftermarket kit contains front CVDs and rear axle shafts sized for TRX4M scale crawlers, produced in medium carbon steel to balance toughness and weight. With the supplied brass +5mm spacers the set widens the track at each wheel, helping to reduce roll and sharpen steering input on uneven surfaces.
The components are intended to be fitted at the front CVD locations and on the rear axle shafts as a tuning change to widen track width without modifying wheel diameter or core suspension geometry. After installation, check wheel arch clearance and steering link travel to ensure smooth, bind-free operation.

Good for scale trail use where a small track increase improves composure; the medium carbon steel shafts and spacers create +5mm per side width but always confirm hub and steering clearance before final assembly.
