All Mazdaspeed 6 owners know that at some point after a few hard launches, the bearing caps in the transfer case/PTO will fail and leave you searching for an entire replacement transfercase. An upgraded replacement option was offered for a limited time but is no longer available until now. SPEED PERF6RMANC3 now makes a set of upgraded bearing caps for the mazdaspeed 6 transfer case. These are made from a single block of billet 6061 aluminum and finished to a tolerance of +/- .001". You can be sure that after installing these you will never have any more issues with broken bearing caps that destroy the transfercase. These have been tested in many of our 700+ WHP customer cars with no adverse affects.
• Professionally engineered (not copied and re-made) by one of the top manufactures on this platform using high quality materials and excellent quality control.
• Track tested in cars producing well over 700 horsepower at the wheels, running low 10 second times.
• Trusted in the highest horsepower world record holding MS6.
NOTE: Tighten bearing cap bolts to factory torque specs.

Stock or fully bolted MS6 these are a must have to keep power on the ground. Saves your transfer case from death!!

Despite my transfercase for some reason having dowels for two of the three bearing caps I replaced, the upgraded caps centered nicely and torqued down. With shockproof fluid (a bit overfilled) and these bearing caps, I'm hoping to not blow up any more driveline components!
