Grublock Motor Mount for Arrma 6s BLX Platform

The popular PPS Screw Adjuster Motor Mount has gotten an upgrade! 


After over a year of people loving the original mount, I have decided to give it a refresh. 

This motor mount will mount either a 25mm or 30mm spacing motor***. It features a screw driven mesh adjuster with a robust locking mechanism. It boasts all the same specs as the original mount, but will have a little more gear range. 

It will work in all Arrma 6s BLX cars that are V4 and newer. 

Mounts and mount combos will also include ALL NEW hardware, as well as the tools for the adjuster. 

Motor Mount Combos are also available. They include the Grublock Motor Mount, Differential Brace, and Differential cap with your choice of E-brake or Roll bar mounts

*** 8mm shaft motors will need to have a 30mm long shaft, and the pinion will need to be mounted flipped. This is a very common and standard thing, however there are some oddball motors out there with 8mm thick 20mm long motor shafts. Basically if the shaft is longer than your stock motor, you should be all set. And MOST of them are.

 FOR THE LIMITLESS V2, YOU MUST PURCHASE THE COMPLETE COMBO. You cannot use the motor mount only with the Limitless V2 Diff Cap and Diff Mount.

Amazing engineering. Fit perfect and holds the gear mesh perfect. I highly recommend it if you are installing a big can motor.

Fantastic Motor Mounts

Just ordered a second Grublock Motor Mount Combo for a new Arrma Limitless, with the switch mount for the Castle XLX2, in addition, a Grublock Motor Mount for my Felony. I have been using one on my first Limitless and love it, makes setting the gear mesh up a snap along with changing motors to coke cans. No issues and several crashes at 120 MPH plus and no harm to mount.
