Many of you knew Frank Bowman as the "Ring Master". When we purchased the business to carry on the manufacturing of quality rings we needed a new name. RMJ was decided on because Bjorn has now become Ring Master Junior. He spent many months training and learning the techniques of making the same quality rings that Bowman rings were know for around the world.
WHEN ORDERING YOUR RINGS YOU WILL HAVE AN OPTION FOR GAPPED OR UNGAPPED.
-Gapped- We file the ring ends to a 0.001" gap.
-Ungapped - We leave the ring ends for the customer to file/fit to their satisfaction
*Once our packages have left the UNITED STATES the tracking information is not guaranteed as accurate. It's up to the receiving facilities to update the information. Often times packages take longer to arrive because of being held in CUSTOMS. We make every attempt to locate lost packages from our end when we are notified that this has occurred.

We have many other rings available. If you do not see your engine/model listed please contact us.
