BMW S55 Engine Pro-Series 18.8 Cylinder Head Stud Set


Replacing the original cylinder head screws with high-strength Pro-Series 18.8 studs.
This is necessary when making large increases in performance, as the original cylinder head screws elongate during operation and the cylinder head can lift off.
The Pro-Series 18.8 stud bolts with a tensile strength of 1850 N / mm² provide a solution to this.

In addition, these stud bolts do not have to be replaced after dismantling, but can be reused.

Technical details:

  • Manufacturer part number: P102081410
  • Kit content: 14 stud bolt (M11) / 14 nut (M11) / 14 washers / assembly lube/ assembly instructions
  • Tensile strength: PS 18.8 steel / 1850+ N/mm² (270.000+PSI)

The Pro-Series 18.8 sets are high-strength stud bolts manufactured in Germany.
A special steel is used which, after tempering, has a tensile strength of 1850 + N / mm².
All threads are formed and not cut as usual. The so-called rolling of threads can increase the strength of the tooth flanks by around 30%. All Pro-Series products are supplied with a nickel coating or optional with a burnished protecting against corrosion in the long term, even under the toughest conditions. Pro-Series stud bolts have a hexagon socket drive on the head side for screwing in the stud bolts. Due to a cone on the engine block side of the bolt, these are not supported on the thread flanks when the nuts are tightened, but in the bore of the thread in the engine block. This support protects the threads when racing engines are frequently rebuilt.

Pro-Series advantage over other manufacturers is the nuts and washers included in the set, these also have a tensile strength of 1850 N / mm².

Great value and quality, runs slightly small.
This is a great deal and fit perfectly! My kid is more of a size 10 but I ordered size 12. It's only slightly big in the waist but the pants have elastic adjusters so we were able to make it work. It's great quality! We ordered yellow for a school play but I plan to order other colors because my kid feels like a million bucks in his new suit.

A great option for those looking to save some money!
Color: Black, Size: X-Large, Color: Black, Size: X-Large
Last May I got married in Alaska on a glacier. I wanted a suit/tux that would not only look halfway decent, but one that I could expose to the elements and not feel too bad about ruining. Luckily, nothing was ruined and it ended up looking great! The fit overall was relatively true to size with the jacket being a hair too narrow for shoulders. The material was surprisingly very comfortable and well made. I have a longer torso and the jacket was the perfect length as well. I've never been one to go all out spending a ton of money buying or renting a suit or tuxedo, so this was genuinely a lifesaver at the time. If you're in a pinch and need something nice to wear, or just looking to save some money, you won't be disappointed.

My Husband Gets SOOOO Many Compliments
Color: Royal Blue, Size: X-Small
My husband has a closet full of suits. I try to make sure he has 7 suits available to wear, so when his blue one started looking bad, I started looking for a new one, but with inflation money has been tight lately. I saw the price and the reviews on this one and thought, why not take a chance. Wow! I'm so glad I did. He loves it and he looks great. Every single time he wears it, people are like, where did you get that? That's a nice suit, and these are people who where suits (and their wives who know suits). The next time we need to replace a suit, I'm coming right back. He loves wearing it because he is always very comfortable and so far, it hasn't shown any signs of wear. The material is on the thinner side, but thicker than linen, and keeps its shape nicely. When we first got it, I steamed it, and I haven't needed to iron or steam it since, but he does keep it hing up when he isn't wearing it. Tip: use the size guide. I was very hesitant to buy a size as small as it was saying for my husband, but it was right on point. It is an absolutely perfect fit.
