Tamiya 54618 OP.1618 Rigid Separate Suspension Mounts (1XB) - Precision Spare Parts  [54618]

Stiffen Chassis Control with Tamiya 54618 OP.1618

The Tamiya 54618 OP.1618 Rigid Separate Suspension Mounts (1XB) are engineered to improve stability and handling for your RC car. These mounts let you make precise chassis adjustments by changing suspension shaft width and toe angle. Machined from lightweight yet robust aluminum, they form a firmer attachment that sharpens overall vehicle response.

Fitting Locations and Compatibility Notes

These mounts suit front arm attachment points and rear suspension locations where toe adjustments are required, making rear toe-in tuning straightforward. While intended for the TRF419 chassis, the mounting pattern allows fitment on other models with similar suspension geometry. Optional setting spacers, such as Item 54617, are useful for fine tuning if needed.

Mount Types and Width Options

Tamiya supplies three mount styles to alter track width: 1X, 1XA, and 1XB. The 1X parts are the standard kit pieces, while the 1XB set provides a narrower profile for further setup changes. Each package includes matched A and B mounts so you can combine positions for balanced geometry.
