OVERDOSE Adjustable Aluminum Rear Upright – OD / YD-2 / YD-4

Upgrade your RC drift chassis with the OVERDOSE Adjustable Aluminum Rear Upright Set, designed for advanced suspension tuning and improved rear-end setup flexibility.

The upright uses a 2-piece construction consisting of an axle mount and upright base, allowing multiple geometry adjustments without replacing the entire upright assembly. This design gives drivers more control over toe angle, track width, axle height, and upper-arm position for fine-tuning traction and handling.

The toe angle can be set to 0°, 1°, or 2° simply by changing the screw mounting position. Because the design isolates toe adjustment, changes can be made more predictably during chassis setup. Five upper-arm mounting positions further expand tuning options.

Track width can also be adjusted by changing the spacer thickness between the axle mount and upright base. By reversing the axle mount, the axle height can be set to either the standard position or approximately 2mm lower.

Steel adapter pipes are installed at the suspension pin mounting points. The uprights support both 2.0mm and 2.6mm suspension pins, making them compatible with OVERDOSE chassis as well as Yokomo YD-series platforms. A dedicated axle shaft is included, and OVERDOSE notes that a driveshaft approximately 3mm shorter than your current shaft may be required.
