exclusive applications, we are ready to get your hardware to you

We have all popular BMW hardware from Raceware and ARP for
every high performance need.
First off; why are head studs better?: Despite the fact that BMW engineers some of the
worlds most revered engines, during number crunching something
always has to be a compromise.
One item that is always found to be a weak point- the OEM hardware.
It is definitely sub-par for real performance use under high stress
such as modded engines and track use.
Whenever the head is coming off, your switching to forced
induction, or if you are simply prepping to drive your car hard; we
highly recommend switching to far superior race-grade hardware.
These Head Stud Kits greatly improve reliability; helping to
eliminate movement of the of the cylinder head and intern, gasket
failure caused by inferior OEM head-bolt stretch.
This is the #1 cause of premature head gasket failure, especially
on boosted or high output engines.
Though more expensive than OEM, converting to one of our head
studs kits will not only give added strength and reliability when
its needed most, but provides the most accurate torque readings
because studs don’t “twist” into the block; all clamping forces are
on one axis, and there is less force exerted on the normally
stressed threads of the block. This increases block and hardware
life and typically makes the head easier to properly install to the
block, a blessing if your head may have to be removed more than
once.
Especially in the time crunch of racing, when engines are
dissembled frequently, studs make removing and installing the
cylinder head on to the block a much easier task. By allowing the
studs to act as a guide on to the head, your head slides on and off
and also ensures proper alignment of the head and gasket for the
same reason. It is similar to converting your wheel-bolts to
wheel-studs.

- FAQs-
Q: Do I need Head Studs?
If you are on our web site, chances are head studs are worth
considering and are a good choice for you.
Any use of forced induction, any racing, or if you plan to be
removing the head in the future is a firm recommendation for using
Head Studs. They are just better!
Q: ARP 2000, L19, Stretch Hardware?... what's important that
I should know?
There are only two instances on BMW where this is all important;
the M50 family engine including M50, M52 S50us and S52us. The
second is the S54
- First, all OE BMW Head stud hardware is stretch type, meaning
that once used; it should be discarded as it is no longer capable
of doing its job.
- ARP2000 offers improved strength over standard head stud
material making it ideal for forced induction and racing use: This
is our preferred M50 family head stud.
- L19 head studs for the S54 are used on our high HP builds where
more than 600 WHP will be used. These are recommended for our
custom and high-HP FI customers
- Aluminum Block Engines Use Raceware Head Stud Kits and
must be time-serted for proper installation. Inquire about
our Time-Sert kit or our in house proprietary time-serting
service.
