Trash product. Failed after 1 week. Do not recommend buying. Terrible return policy worse customer service. Will never buy any of their trash again. Read the terms. Weather you have received the product or not after 3 days you're screwed.

When I ordered the manual brake conversion kit I had a question and the response time was right away. The part showed up in 2 days awesome place to order from.
Rob G. 5/5 Verified
Had to get longer bolts for the top two holes so I could add a proportion valve. Other than that, its an easy and great upgrade.

Master Cylinder shipped fast! Showed up after couple days after being ordered, easy to install and to remove my brake to drill a new hole and set up the new push rod at the right angle. Works better now than ever before!

Great product
Jacob H. 5/5 Verified
The ports are in the wrong side of the master cylinder
Michael D. 1/5 Verified
Well it all looks good, but no instructions as to location for it, bracket doesn't match firewall, so I'm guessing I need to either cut the firewall or just locate the unit where ever I can. Not as cut and dry as thought

Great product, fit well and instructions guide through install.
