This is a custom set of ARP 2000 high performance BMW N54 head studs.  All studs have 1.5" thread engagement with bullnose specifically designed for aluminum blocks and high clamping loads. ALL the other ARP stud kits for the N54 oont he market only have 1" thread engagement as they are made for Iron block not specifically for Aluminum blocks.  It is actually studs from a Chrysler 2.2L kit iron block re-purposed for the BMW N54 and even though "they fit" the poor 1" thread engagement will rip out and lift the head and damage the block with high boost, they are worthless for the N54 high power application and it is actually better to stick with stock bolts that are almost as strong as those k and the stock bolts have more tan 50% thread engagement than those other kits.  With my kit you get the STOCK FULL thread engagement 1.5"+, and a stronger bolt and a better design stud vs bolt so big improvement all around, with those other kits its a waste of money and will led to failed block threads.  Even just torquing to the ARP required 90 ft-lbs on the M11 studs the others sell with just 1" thread engagement into the aluminum block can rip out the threads sometimes in the aluminum block.

This kit is deigned for anything from OEM to high boost high horsepower loads  while maintaining a high integrity of head sealing under very high power conditions.  No modification is required to the OEM head to install this kit.  When it comes to high performance quality head stud kits, nothing is better than the ARP brand!
