#75190 - ONE-WAY GEAR BRACE (ALUMINUM/PURPLE)
PRO 4/Helps protect one-way bevel gear
HPI now offers three options to improve the strength of the Pro 4 drive train when using a front one-way diff. The 75190 purple anodized machined aluminium brace adds support for the 39T Bevel Gear, providing extra durability that helps protect the driver train from crash damage.
Also the #73501 Bevel Gears have been updated and reinforced to improve strength. The new version is a direct replacement for the older bevel gears. The part number will remain the same. To achieve an optimum bevel gear meshing and efficient drive train, you can use the #Z891 copper colour 0.1mm washers. Together with the already available #Z892 washers with 0.2mm thickness. These new washers give you optimal control over the gear meshing of your Pro4 bevel gears and thus optimal performance and durability. The combination of all three parts will significantly improve the strength of the Pro 4 drive train when using a front one-way diff. All parts are available as option parts and all new Pro 4 kits will be equipped with these new parts. #75190 - ONE-WAY GEAR BRACE(ALUMINIUM/PURPLE) #73501 - BEVEL GEAR SET (39T/16T/SPACER) updated #Z891 - WASHER 10X12X0.1MM (COPPER/10 PCS)
