Product Overview

The Draco Centre Diff Set 2024 is here! This is an updated version of the previous one released in 2022. The Centre Diff Set is designed for the Savage Series and Savage based platforms. It is a custom set that replaces the stock centre transmission. You are able to use a Centre Diff which simplifies the drive-line and adds additional tuning and gearing options. The stock HPI diff case (HPI86827) is compatible with the included Draco 52T Spur Gear. The included ESC Mount is located at the top of the set, but the Centre Diff Set can also be installed without the ESC Mount. Other features include bearing-supported outdrives front and rear for additional support of the drive-line increasing reliability and durability. With the ability to use 11T to 22T MOD 1 pinions with the Draco 52T Spur Gear, this allows you to fine tune the perfect gear ratio for your vehicle. With bottom access to your centre diff, you can easily and quickly change out oil or maintain parts. Access the diff by removing only four M4x25mm/M4x30mm screws.

WARNING: Direct drive systems like the Draco Centre Diff Set can increase motor temperatures, please regularly check your motor temperatures while running.
