John G. 
United StatesGreat upgrade
I upgraded the original plastic z axis carriage with this. The installation is straightforward. You may have to adjust the location of your boards on the x-axis beam so your wiring has enough slack. The quality is outstanding. I love the z-axis adjustment know on top of the stepper motor. I can quickly set z on different size items without jogging the stepper motor via the computer. A little disappointed no adapter is being offered for the 5.5 laser but I’ve ordered one from an online 3D printing service using the spec-file Sainsmart provided. I also made one myself out of wood to get me by until the ABS one arrives. Keep in mind you’ll lose about 5mm travel in each direction on the x-axis as this carriage is wider and beefier than the plastic one.

CanadaWhat a difference
It fit perfectly and reduced the vibrations. I can now machine gears with no chatter marks. If I could recommend an upgrade it would be this!

Les A. United StatesAwesome
I bought the 3018 Prover and the bed add on to make it 3040 Prover then upgraded to 300w spindle and aluminum carriage. I have to say everything was better than I expected and cuts great. I would give the entire machine and transaction 10 stars if I could.

Rod S. United StatesAluminum Spindle holder
Haven’t had a chance to use it yet waiting on bits. Very good setup includes limit switches too. Easy instructions on changing it over. Larger spindle motor fits great and snug without any play.

A W. United StatesClear instructions, easy install. Aluminum Spindle Holder Upgrade.
Nothing to complain about. This spindle holder is very sturdy, it put my 3018 Prover at another level. By itself I rate it at Five Stars, however, there is no adapter for mount my LASER. Hence the Four Star rating.

Anonymous United StatesMore power...
This spindle motor is far more powerful than the original little GS775, 24 volt spindle motor. This spindle motor uses a variable 0-48 volt power supply - twice the voltage, twice the RPM. It's well worth the USD $99.99. To effectively use this more powerful spindle motor, you will also need the Genmitsu Aluminum Spindle Holder for 3018PROVer, costing an additional USD $99.99. It takes about a half hour to swap out the old, for the new... It's well worth the extra cost. This machine will make a great printed circuit board fabricating machine!
