Shellplate Bearing Kit Dillon RL 550, RL 550B, RL 550C kit includes the very popular shellplate bearing kit, index sprocket, and extra length shellplate bolt. The bearing kit provides smooth indexing with tighter tolerances. Tactile feel for priming is enhanced and more consistent priming is achieved. No adjustment of dies required.

Please watch the video in this listing. It contains the setup and adjustment information for your kit. The video covers installation for all variations of our kit, some chapters may not apply to the kit purchased. Instructions are not supplied with the kit.

When installing the extra length bolt, don't forget to loosen the grub screw on the left side of the ram before removing the bolt, then tighten it back up after reinstalling. 

We found that the 550 presses simply eat non-metallic detent balls. So we stopped including these with our kits. The 550 relies on the detent ball to position the casings properly. The best solution is using the steel ball supplied with the press. If still interested, the our phenolic resin low mass ball sold for XL650 presses will fit and is sold separately.

Our kits were featured in the Nov/Dec 2011 issue of Front Sight magazine.

Our best kit for the 550 is the Ultimate Shellplate Bearing Kit, or click here to see our eBay Store and all Shellplate Bearing Kits. Kits are available for RL 550 B, RL 550 C, XL 650, Super 1050 and RL 1100.

All of our kits and components are made in the U.S.A.
