What is the benefit of carbon blocker rings & micropolish internals
Just ordered a level 4 magnum from rpm. Just thinking maybe I should have went with level 5 with carbon blocker rings or even level 6 with micropolish. What are the benefits of these options? Can't find a clear answer.
Carbon blocker rings replaced the paper ones, IIRC, somewhere back in 98-99. While I suppose paper could be found to use in a rebuild Carbon is what Tremac started using back then.
With carbon blockers you can use synthetic fluid as the paper did not, over time, hold up well with synthetic fluid
some with a higher pay scale than me re: trannys can comment on benefits/need for micro polish

I doubt it. Ask the vendor you choose what it has.
Given Tremac stopped using them in the T56 around 98, I would think the later version, Magnum, uses carbon. But again, ask the source of your tranny purchase
Magnum synchronizers have brass lined, triple cone blocker rings except 2nd gear rings are carbon fiber lined.
I just finished going through mine and replaced 1-4 blocker rings with the cf lined rings (TUES10357). Same used for 2nd gear.
To use these cf rings for 3rd and 4th gear, the original, thicker inner rings have to be reused.
I did this modification at the direction of George at Rockland Standard Gear. It shifts great after it gets warmed up with Amsoil Synchromesh. Going to try some Redline D4 next.

So do they last longer? Make shifts better? Handle more power? I'll cal rpm and ask Monday. But what is the real benefit . They seem expensive option I think $550 at rpm

The carbon fiber will endure more abuse than brass. I smoked the original fourth gear synchro blocker rings on one missed shift.
Micropolishing removes any excess flashing left on gears and shafts after the original machining process. When you have metal on metal running, the polishing helps reduce friction which in turn reduces heat build up and creates a smoother shift and it can also reduce vibration with less wear and tear on bearings and other parts. I have an RPM stage 5 T-56 and I can tell the difference between what the original setup was and the upgraded version. I run the Redline D4 fluid and it shifts good still have to let it warm up some though. The polishing can also reduce failures by removing the stress risers as they are referred to. I will try to explain what a stress riser is for those of you who may not know. Stress risers are sharp edges or can also be grind marks left from a machining process which can and will cause a failure in that particular area of the base metal material in which the gear or shaft is manufactured from, by removing these areas and smoothing them out (blending) as we call it in the business I am in (ASME Pressure vessels) we can eliminate the material from breaking or cracking. Hope this helps! I am by know means an expert but have learned a lot over the 37 years I have been in metal fabrication.
