Happy with the product, had my M273 quad cam CLK up and running in short time. Especially with the prompt international delivery to NZ!

I had a problem where my belt would squeal under cold conditions so I decided to buy this kit and it has been flawless since I installed it! I absolutely recommend replacing the tensioner and the pulley if you're planning on replacing the belt as they all have similar service interval! This kit provides everything you need for preventative maintenance!

Put it in 2 weeks ago, everything seems to work fine. It got rid of my cold start squeal.

Fits 2008 E350 4Matic. Easy to install, first time ever messing with serpentine belt and all went smooth. For my said car you will need an E-12 star socket for the upper idler pulley and the tensioner, and an E-10 star socket for the lower idler pulley. You will also need a 17mm socket for the tensioner release. Job took me 45 minutes. Though I spend some time looking at youtube vids before hand.

KIT WORKED OUT PERFECTLY AND A GREAT ALTERNATIVE TO GENUINE PARTS AT A FRACTION OF THE COST!

perfect fit, belt size, and idlers...all had stock markings and a MB belt. Car had a small squeak at idle which this kit fixed. It is now silent.

I have a 2008 Mercedes E350 Sport Sedan. Installed everything today. Both idler pulleys, serpentine belt, and belt tensioner. All the parts fit perfectly. No more squeaky sounds coming from the engine bay anymore. Pretty sure the original lower pulley and belt tensioner were perfectly fine however the belt and top pulley absolutely had to go. Figured I'd just change out everything while I was in there. It's not that hard to DIY there's a lot of videos on YouTube I watched that were very helpful. The hardest part is getting that bolt in the tensioner to lock it so you can take the thing out. Sacramento Mercedes dealership quoted $1500 for parts/labor to do this job. Total waste of money. You can do this one yourself gents. Belt Tensioner torque spec = 35nm or 25.5ft-lbs Idler Pulley's torque specs = 25nm or 18.5ft-lb

10Q guys I received the parts super fast and was able to DIY JOB !!!! You guys saved me a lot $$$&$ no more rattling sounds and I feel very satisfied !!! Great to do business with you !!! 10Q

Was exactly what I needed when I changed the front diff fluid in my GLK350, as you have to remove the alternator.

Perfect fit
