550 Series

We spent some time looking at reviews and reading the forums to find out what we could do to improve this kit. A show stopping problem has been how thin the webbing is between the sprocket fingers. This makes the sprockets fragile and fingers break off, but not our sprockets. We have more metal than any other product on the market. Our sprocket is the strongest available for use with a bearing! Does not fit 450 presses.


Ultimate Shellplate Bearing Kit for Dillon RL 550 B/C (550U) $35.95 Free shipping in U.S.A.

Ultimate Shellplate Bearing Kit Dillon RL 550 B/C replaces the index sprocket with a modified sprocket that has the room required to install the shellplate bearing kit. Run out is eliminated and this results in more consistent ammo. The bearing kit smoothens the action of the press, reducing powder spillage and increasing tactile feel while priming. Priming operation will be more consistent. With 3 powder measure adjustment knobs. The powder measure knob is a simple press fit. Press it onto powder adjustment bolt. After a day or two, the plastic will form to the hex bolt head. This kit works with both new and old style powder measures. The extra length shellplate bolt allows us to provide you with a robust index sprocket. We cast our own sprockets, less metal is removed to make room for the bearing. 550s need this extra length bolt. Does not fit 450.

Very detailed and complete instructions are included with the kit. If you have any problems send me an email and I will call to help you finish the setup.

750 / 650 Series

Ultimate Bearing Kit for Dillon XL750 / XL650 (750U) $47.95. Free shipping in U.S.A.

Ultimate Bearing Kit Dillon XL650/XL750 adds a roller bearing on top of the shellplate to reduce powder spilling as the shellplate snaps into position. We also include a Camming Pin Bearing to replace the camming pin. Your press will run as smooth as silk with this kit. Our tough as nails low mass detent ball is included. Run out is eliminated and this results in more consistent ammo. The bearing also supports the shellplate resulting in better priming. Ultimate kit includes the very popular Shellplate Bearing Kit, Ejector, and 3 powder measure adjustment knobs. This kit works with both new and old style powder measures.

Our Camming Pin Bearing reduces friction and smoothens the reciprocating action of the case insert slide and slide cam. A special cut allows the casefeed arm to function correctly, there are some older 650s that really benefit from this. All of our camming pins are blued and finished. We match the dimensions of the OEM pin. Our pin fully supports the casefeed arm, reducing vibrations and unnecessary wear. Reduced vibrations helps to keep cases correct side up when using a casefeeder. This is an exclusive feature of our pin, not available from any other manufacturer.

Our Ejector eliminates case binding and the need to tune the ejector wire. Tuning the ejector wire was one of the biggest complaints we heard from users of the shellplate bearing kit.

Detailed instructions are included with the kit. If you have any problems send me an email and I will call to help you finish the setup.
