Tekno RC NB48 2.0 Adjustable Ackerman Spindles & Bearing Spacers

The Tekno RC NB48 2.0 Adjustable Ackerman Spindles and Bearing Spacers provide adjustable Ackerman tuning for the Tekno RC NB48 2.0, EB48 2.0, and ET48 2.0. Different-length spindle arms can be used to adjust steering characteristics for corner entry, middle, or exit.

When paired with an optional longer camber link length, these spindles are designed to improve front-end stability and responsiveness. Due to the reduced incline angle, the camber and steering links will need to be adjusted.

Setup Notes

• TKR9047A: Recommended for lower-grip, open tracks; provides more initial low-speed steering with less middle and exit steering.
• TKR9047B: Recommended for medium-grip, mid-size tracks; provides a more balanced entry, middle, and exit steering response.
• TKR9047C: Recommended for high-grip, tight tracks; provides less initial steering with more middle and exit steering.
• TKR9047A is recommended as the starting option because it has the same Ackerman length as the original TKR9041 spindles.

• (4) 3x4mm Set Screws
