Toyota billet center support bearing. These replace the pesky stock bearings that never last. When you modify the rear suspension on a 2WD tacoma, or tundra, you have to add a slip yoke to the rear of the drive line. This creates and issue because now you have a transmission tailshaft slip yoke and a slip yoke in your driveline which distroys the factory support bearing almost immediatly. This new replacement carrier bearing is designed to take the plunge load off of the tailshaft on the back of the transmission and allow all the plunge to be in the rear driveline where you added the slip yoke. THIS WILL NOT WORK WITH STOCK 2WD DRIVE SHAFT, YOU NEED TO ADD A SLIP YOKE TO THE BACK HALF OF YOUR 2 PIECE DRIVELINE. This is the new updated version that WILL WORK for 4WD model as well. 
These fit, all tacomas ( 3rd gen 2016-up are different AND WONT FIT. Some 2016 models use this style. Message me for fitment question on your 3rd gen style coming soon!), all tundras, toyota pickups (SMALL MOUNT MODIFICATION ON THE TOYOTA PICKUPS). They come standard with quality TIMKEN bearings and are machined from 6061 t6 aluminum, fully assembeled with hardware and bushings (NOW OPTIONS FOR SOFTER BUSHING FOR DAILEY DRIVEN TRUCKS).
Your driveline will need to be in good shape to run this product. If it is out of balace, bent, driveline angles incorrect, or has worn out parts you will get a vibration. IT IS 100 PERCENT THE INSTALLER'S RESPONSIBILITY TO MAKE SURE YOUR DRIVELINE SETUP IS CORRECT TO RUN THIS PRODUCT.. The stock bearing masks 99 percent of most problems that will come to a head with the more ridgid style support bearing.
