Product Information

Lee ultimate spline drive lock rings. 3 pack of gold anodized aluminum lock-rings with o-rings.

One wouldn’t think you could improve on a simple thing like a lock ring, but we have. The new split clamp spline drive makes all other lock rings obsolete and clumsy to use. We started with custom extrusion of high strength aluminum with a splined exterior surface. We split the ring, and added a cross bolt that when even lightly tightened, applies a vice like grip on your dies. No tiny set screws that easily strip or damage your die threads. Then we added the famous Lee “O” ring because no matter how securely you have the lock ring clamped to the die, it will loosen in the press during operation without the friction of the “O” ring. The “O” ring allows you to finger tighten into your press and it will never loosen during operation yet you can easily remove your die with finger pressure. We have also included a handy slim profile lock ring wrench, works great when fitting dies on a turret or tool head. Dies are simply easier to install with the lock ring wrench.

  • Compatible with 7/8 x 14 threaded Lee reloading dies and Lee reloading presses.
  • Torque type splined exterior, for a no-slip grip.
  • "O" ring, anti-rotation, included. Never loosens during use.
  • Lock-ring wrench included.

Work perfect on my Lee Progressive press. Makes a much better fit when replacing rings from other dies.

Lee Die Rings

By Gary D. on Jun 14, 2023
These rings work on all 7/8-14 dies. They are very easy to adjust the rubber O ring keeps the die from moving once it is set, it is also very easy to make fine adjustments on the die to tweek it in if needed. Would recommend these rings over any other.

The best lockring available

Better than expected for Lee products. Extremely consistent construction and the little plastic wrench is perfect.
Do yourself a favor and pull the O-rings out

I like these lockable rings

By Michael E. on Dec 11, 2019
These work great on my Lee turret press. Now I can tighten the dies down and then lock them down. I have seen on other sites that people were having trouble screwing these on but the old Lee die rings have the same resistance when screwing them on. The O-ring is what is tight. Once you take them off a few times they loosen up a little.
