Feature:
Multi-displacement Svstem (MDS for short) is a unique engine technology; if the engine adopts MDS technology, it can switch the working cylinder of the engine between 8-cylinder and 4-cylinder.At the same time, the MDS system can run with 4 cylinders or 8 cylinders by judging the engine load and working conditions. The engine closes 4 cylinders symmetrically, and the remaining 4 cylinders form a V4 engine, so that the engine can still maintain Better ride comfort; in addition, the data given by engine manufacturers equipped with the MDS system is a 20% increase in fuel economy.
This technology is most suitable for multi-cylinder engines, and effectively reduces fuel consumption during traffic jams without affecting the driver's pursuit of the acceleration stimulation of large-displacement models. For example, after a conventional 8-cylinder engine adopts this technology, it is equivalent to installing two independent 4-cylinder engines, which can run one engine and let the other rest according to the needs of driving.

Bought this kit mainly to replace the lifters on a 2012 Ram 1500 5.7l, didn’t end up using the cam as my lobes were good, but the kit did the job. I bought Fel pro head bolts though.
Perfect product and shipping was 2 days and everything fit perfect and had no issues every part was flawless.
I installed this camshaft, rocker arm, and lifter kit on my 3.6L Pentastar V6, and suddenly my engine sounded like it had been to the spa. Gone is the annoying ticking noise, replaced by smooth, confident operation that makes me want to take long, unnecessary drives just to listen.
The kit is impressively complete—intake and exhaust camshafts, rocker arms, lash adjusters, and all the gaskets you need for a full top-end refresh. Everything fit perfectly, and the build quality feels solid; you can tell these parts were designed to last, not just look good in a box.
Since installing, performance and efficiency have noticeably improved. My fuel economy feels steadier, and the engine revs more smoothly. Even for a DIYer like me, the process was surprisingly straightforward, and the results are extremely satisfying.
If your Pentastar V6 has been giving you headaches, this kit turns a worn-out top end into a quiet, responsive powerhouse. Durable, well-made, and ready to make your engine feel like new again.
Buying these four cams locally. We're around $1,000 so I took a gamble on these and I'm very impressed. So far the engine runs very smooth. I have over 10,000 mi on them at this time I guess we'll see how long they last. I do courier work. I put about 170,000 plus miles on my car every year so it won't take long to see if these last a while
I have 27,000 mi on these cams now and running as good as the day I installed them
At first I was very skeptical due to cost. I purchased all four camshaft for the price of one from the dealership. The job is not hard if you follow the proper steps. A must have is the timing tools. It makes the process so easy. After tear down and assembly the jeep fired off on the first crank. Very satisfying. Great investment.
