APPLICATION: WORKS WITH SAVAGE 21 RTR, 25 RTR, & 25 SS

Now available from HPI Racing are new Heavy Duty Cup Joints for the center drivetrain of the Savage monster truck! These Heavy Duty parts will reduce drivetrain wear and extend service intervals, perfect for high horsepower engines and extreme conditions.

These HPI86277 8x14x19mm heavy duty cup joints replace the stock HPI86083 cup joints. These heavy duty cup joints go on the input of each differential. 1 pack of these contains 2 cup joints which is enough to upgrade both differentials on a Savage truck.

RECOMMENDATION: If you want maximum durability, you should replace all the cup joints and the differential input shafts/cups with the HPI heavy duty upgrades. We try to stock these heavy duty upgrade parts... to see these items use the SEARCH at the top of any page to search on the listed part numbers:

HPI86276 - HPI Savage HD Cup Joints 6x13x20
HPI86277 - HPI Savage HD Cup Joints 8x14x19
HPI86278 - HPI Savage HD Differential Shafts

When upgrading to these heavy duty cup joints and already having the truck taken a part, Savage owners may also be interested in upgrading to the HPI Savage Heavy Duty Chrome Dog Bones (these come standard on the Savage SS kit):

HPI86151 - HD Chrome Dog Bone (C-Front)
