These are high end half shafts, made of the highest grade materials, and biggest yokes that a stock w201, w124 or r129 can adopt. The splines of the hubs are upgraded to 33mm ( for comparison all w201/w124 come with 25mm splines, and all w140/w220 come with 27mm splines). These half shafts can handle up to 1000 nm with ease, which is twice more than the strongest ones installed on w124 and w201. Weight is moved from 7,8 to 9,3kg which means 25% more weight, with 100% more strenght! The kit includes new wheel knuckles, hubs which are made to adopt the bigger splines which is one of the biggest problem of people with powerful w124/w201 and etc. You receive what you see on these pictures: - 2 half shafts with yokes made in Japan - 2 machined wheel hubs with 5x120 and 5x112 holes and 33mm splines - 2 new nuts for tightening the wheel bearings - 2 new preinstalled bearings - 2 new uniballs preinstalled in the wheel knuckles - 2 new centering plates for the half-shaft flanges to the differential - Anti-Rust Nickel coating for the hubs and wheel knuckles - 33mm splines for the hubs - 38mm splines for half shaft length adjustment FEEL FREE TO ASK ANY QUESTIONS REGARDING YOUR REAR SUBFRAME AND DIFFERENTIAL COMBO!
