marqcad is good quality and Ryan makes some awesome stuff for defenders and other machines. He isnt some over seas knock off and is worth supporting if you want to buy something. he is in WI and sponsors racers, etc. not just collect money and run. its too bad that people are so quick to jump ship on something that is well thought out, works well, and is a little more expensive to find some chinese or indian knock off to copy it after someone puts in the hard work to design something nice... you buy a 30k machine and complain about $350 for something that is to help make life easier...
Guys that have the kit love them- if it is something that you feel you need, it will definitely make an oil change on a limited a lot faster and less messy. anything except the limited isnt really a big deal anyway. the limited has extra stuff on the block that are in the way, i think it is a compressor or something for the AC unit. the rest of the blocks are wide open in the back and very easy to change without additional items. flip the box up and change it in 10 minutes.
