Redline Shock Prood

Anyone running Redline Heavy Duty Shock proof in the rear? We are running a 10" ring gear in a Strange Ultra looking to improve live span some. Ive been using 75w 140 Lucas Syn currently.

Thanks for any info

Always ran it and always have better luck with gears than everybody else.

 

I have what you have. It's not the gear it's the case. The case flexes at the bottom and lets it move around like playdough. I have about 25 passes on my toms $900 10in gear. And he was right. 30 runs it will make noise and around 50 it will break. There is no magic in lube. Strange is not Good quality anymore. I'm saving for a billet piece. He guarantees 200 passes out of his units. By the time you but 3 gear sets. You could have bought a billet unit

 

Im a Brad Penn guy but that Red Shock Proof is the BOMB!

 

As stated, nothing magic about the lube, however, I have been using it in our pulling operation for a number of years and would use nothing else. Started when we used Dana 60's and it improved number of hooks by about 25%. When we went to Dana 80's, never had a failure in five seasons. I now have a 106 and have not changed anything in four seasons (I will refresh gears this winter). I can also say that if the rear doesn't have lube, in our pulling operation, the pinion shaft (Dana 80) will weld the bearing to it in less than 250 feet (that is how severe our rear ends are treated) and spin little curly-Q's from the ends of the roller bearings. I lived and learned. Red Line Shock Proof for me. JW

 

I disagree, there is something close to magic in lubes, that's how I got turned on to Redline products 20 years ago. Of course it's not going cure all problems in every case but I have heard enough game changing experiences from other people's experience with various Redline products that I know it's not just me. I don't have any specific examples of the ShockProof curing mine or anyone else's rear gear issues but if anyone is experiencing a potential lube problem in a rear end and they're not running it I would say give it a try and see what happens.

We have the strange ultra case now. Made numerous 4.0-3.90 passes at 2660lbs with a 50.00 used richmond 9 inch progear.
Made at least 30 laps with a used richmond 4.56 9.5 that everyone said was soft junk. Looked excellent when I sold it.
We currently run a US gear 4.86 9.5 in the low 3.80's at 2530lbs and have zero issues. Per Toms we ran 6 laps and then reset the backlash. He said inspect it again at 100 runs.

 

How much backlash ??? are you running the load bolt ?

 

Overkill and I are partners on a Promod. I can't remember the exact backlash numbers off the top of my head (I have them written down, just not with me) but I think I keep it at .008-.010 at the tightest spot. And we do have the load bolt, I just back it off a slight amount from touching (less than 1/8 of a turn). Who knows how much load it sees but there is no doubt it does some rubbing on the ring gear.

I don't claim to be a god of ring gear set-ups and I really don't do a lot of them but as my partner stated, we haven't had many issues so I feel like I must be getting them pretty happy. The patterns I've seen on a high performance drag race gear can get damn weird looking as compared to the street stuff I've messed with. Mostly what I watch for is getting the pattern as close to the toe side as possible and as deep in the root as possible. Setting up a gear is a time consuming process for me. Also, in my experience, some of the performance gear sets tend to produce a weird ratcheting noise when coasting (very noticeable when towing the car) that I don't like but have never seemed to cause any problems.
