Front suspension system

Good product

Made us very happy building with the kit..

It did not fit well an had to much friction.

Using this for a crawler and the mechanism works with my servo motor. One this is that I had to replace the gears track with my own

The MA78 front wheel steering chassis is great and is one of the more straightforward designs I've seen from technic-style cars. The lower profile fits custom builds better. It uses the shorter-style suspension that I see on most sports car builds; it's a pretty firm suspension so it's best suited for level tracks. I don't recommend this particular setup for customizing a FWD, since the suspension sits where the axle would need to be. It was just odd that the instructions were just plain sheet paper that had been photocopied from an actual building set. Probably means it's incorrectly listed as MOC. However, this is still worthwhile for anyone looking specifically for a front wheel steering chassis for MOC projects or mechanics demonstrations.

No assembly instructions. Not even a picture. Poor fit. Low quality. Factory smell. Bad by every metric.

This definitely is a very very poor quality knockoff. I bought plenty of knockoff Lego and Technic products in the past including beams axles gears etc. And this comes out amongst the lowest of the low. Many of the parts that hold in on the end of axles are either so tight that they hurt your hand to install. Or are so loose that they fall off just from moving them back and forth. The pieces have very harsh visible flashing from the mold. The tolerances are so bad that the hubs that attach to Wheels which should be the star of the show on this thing have several degrees of slop meaning your wheels will move way more than the suspension will if it could move. Which brings me to my next point with the build quality being so bad on so many various different pieces the suspension gets stuck very often and is incredibly stiff. Add that to the already very poor choice of springs and this will not move for anything but the heaviest of technic creations. Honestly the suspension is more of a visual thing than anything else. Also these pieces are not going to last through multiple builds. The ball joints were so stiff that I actually hurt my hand trying to push them together and they have visibly stressed the plastic in doing so. Comparing to the official Lego pieces I have of the same function I can't recommend these under any circumstance especially given that building out this kit on a popular Lego auction site can be done for a mere 14 dollars meaning you're really not saving that much. I'm left with the conundrum of whether or not I actually use these pieces in a build. I know me personally will not be using these along with my official pieces as the quality is so different. Maybe I'll snap together this entire unit built as instructed onto a current build and keep it in one piece but that would be about it. Oh speaking of instructions. The good news is they are literally just photocopy Lego instructions.. the bad news is that they scaled them which means that all of the sections that show the pieces to scale so you can identify the correct ones are completely the wrong size. Also none of the colors in this guide match the instructions. And it was literally printed out on the cheapest quality copy paper with the cheapest ink you could possibly imagine. I have a rear differential with suspension on the way from the same seller and I got to say really not looking forward to building or reviewing it. I updated my review to include photos of the stress being placed on the ball joints no that's not a shiny reflection that's white stressed plastic.
