Goerend has a heavy duty bellville spring kit Goerend Heavy Duty Belleville Spring Washer Kit Dodge Diesel. You should call them up to see if that will fix your issue

I haven't seen any aftermarket rear drums. I was thinking of going with the billet front drum but was talked out of it by my builder. He said he can fit more clutches in the 48re front drum(8) and has had less issues with the stock than the billet. He said the billet is possibly only needed if you're going to be spinning ~5k rpm or more because if the sprag fails the drum will spin at 2.2x the engine rpm. So the stock drums were tested by TCS to fail around 14k rpm so it will fail at ~6363rpm. I asked about doing the bolt in sprag as well but he has only seen the sprag failure if someone did a neutral drop however if you do the bolt in sprag and the sprag happens to fail still then the case will be ruined as well.
Most important make sure the fluid is full and drive it hard the first 1k-1500 miles to break in the frictions and bands, change the filter. You can reuse the drained fluid except do the last quart but I elected to just put new in.

No problem. It's been interesting learning about these things. Yeah going into manual 1st would be good to engage the rear band so it doesn't slip. Okay I gotcha now yeah I did that forward clutch retainer as well. Reb Brown said he has never had one fail but with Sonnax just releasing it and Goerend stocking them he said it would be interesting to try it out. They have been known to break from other sources so anything helps.
How did the converter splines look on your input shaft? We're they twisted? Are you running a Sonnax input? I'm just curious how it has faired since there aren't many that do 1-2 locked shifts. I've heard the Sonnax input will twist slightly and have more resistance to twisting beyond that. Likely the same principle with any billet input.
Oh yeah I missed that about the revmax input. I was assuming Sonnax due to the valve body. I wonder who made Revmax's as I'm pretty sure they don't make them themselves, I know they mainly like to use TCS but I wouldn't be surprised if it they used Sonnax when they started their business. Anyways good deal with the longevity of the input. Cool videos too, it's awesome to see a full size diesel wipe the floor with a car.
