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

Dial in Handling with Tamiya 54618 OP.1618 Components

The Tamiya 54618 OP.1618 Rigid Separate Suspension Mounts (1XB) help sharpen handling by increasing suspension attachment rigidity. By changing the spacing and toe of the suspension shafts you can fine tune chassis balance and steering response. Built from lightweight aluminium, these mounts aim to keep strength without adding unnecessary mass.

How They Are Used on the Car

These mounts are suited to front arm mounting points and are often employed to tweak rear toe-in for better straight line stability and corner entry. Although designed for the TRF419 chassis, the overall pattern fits many other models that require similar adjustment options. Setting spacers such as Item 54617 are optional accessories for detailed setup work.

Choosing Between 1X, 1XA and 1XB

There are three width options available: 1X standard, 1XA intermediate and 1XB narrower for more aggressive geometry. Each pack contains a pair of A and B mounts so you can mix positions to achieve the handling you want.
