Bel Ray hypoid 85W-140 vs Redline Shock proof heavy

[89 fxrs]

Any feedback on preferences between the Bel- Ray Hypoid gear oil 85w-140, vs the Redline heavy shock proof?

[nibroc]

both are fairly tough oils

[89 fxrs]

can someone tell me the difference between bel ray hypoid gear oil and their big twin trans oil?

[Ohio HD]

Bel-Ray hypoid gear oil is rated GL-5, the V-Twin oil is not.

Hypoid Oil is made for Hypoid gears, Harley transmissions do not have Hypoid gears (Hypoid gears are typically used in rear wheel drive differentials).

All a Harley transmission needs is manual transmission lube.

My friend put the hypoid 85w-140 in his 2012 road glide - should he drain and replace it or would it be safe to use?

I was a Redline heavy shockproof oil user for years, but seen a lot come in with condensation/milky oil. When Spectro came out with their 6 speed oil it seemed perfect and used it in my bikes and customers, noticed easier shifting and quieter operation in the 6 speeds. Then Spectro priced themselves out of the market when it hit $25 a qt, the Bel Ray V twin trans fluid is now my favorite, works great like the Spectro, don't see the milky oil like I did with RedLine and it's priced at $15.   It's all I use now.

I've not used Shockproof, but using Spectro, BelRay hypoid and V-Twin oils for years. I think I've got 3 or 4 quarts of V-Twin on my shelf right now, so that's what goes in for the next couple years.
130,000+ miles on an abused 5-speed, so something's working right.

Have been using Heavy Shockproof for 29 years. Never a problem with a gearset which included HD 5 spd. Baker OD 6 spd., Jims OD 6 spd. Never experienced any milky appearance in the fluid, but then when I change, the trans is full operating temperature. Only complaints I've heard is from shop owners, many who park bikes waiting for their turn at service outside for days, in cooler temperatures and do fluid service when the trans is cold or slightly warm. In addition have never heard of a gear box failure related to the lube. Heck not even that bee ess Syn 3 motor oil in a trans.

John I also use Heavy Shock Proof, since 2010. I've never seen any issues with moisture or anything being in the oil that shouldn't be there.


You probably remember this post from JohnCA58 from 2013, where he forgot to refill his five speed with Shock Proof. He ran the bike 400 miles before realizing the transmission was empty. What saved everything from self destructing was the previous fill of Shock Proof left enough film on the parts that the transmission lived.

I've used the BelRay hypoid 85-140 in my 2003 Twin Cam 5 speed transmission for well over a decade, and now have over 225,000kms on that bike with zero transmission problems. Years ago I contacted the Belray tech support and asked what the best thing to use in the 5 speed was, and that was it.I also used the Belray Hypoid in shovelhead 4 speed transmissions for years, just a different weight.Harley has an 80-140 full synthetic gear oil which may be more suitable for a 6 speed.

As with most oil threads, the best type to use, is some.

And when the oil is leaking so bad it runs off the sheet of cardboard you place under it and you have to keep adding to it it's always fresh.

Exactly!


Might be why I have so many quarts of BelRay on the shelf. Some out, some in.

 Shockproof heavy in my Shovel's 5 inna 4 case trans and in my 12 TC 6 speed.  I rarely ride the shovel so it gets changed ... someday. The TC gets fresh every couple years. Always as pink as the day I put it in.  I don't get high miles in.  3500 to 5K per year.

I read somewhere that Top Fuel dragsters dump Shock Proof Heavy in the rear ends, spin them around a few times and then drain it out for weight saving. No damage to the rear ends.

go with what baker recommends spectro platinum , or redline

I had the exact same issue with redline. Used it for years then about 30k miles ago I drained the tranny and the oil was full of condensation. Pulled the cable side cover off and the bearings were full of milky pink oil. Started searching the net and found others complaining about the same thing. What happened? Did they change their formulation? Using Bel-Ray now.

  I don't chime in much anymore...but I have had excellent results using Lucas synthetic 75w140 gear oil. 

[HogMike]

I've used redline in my baker OD6 in my 1995 evo and same in my 2019 bagger grudgebox
Just talked to them last week on another matter and he asked about my oil.
Told him about the redline on both trans with high mileage on both these bikes.
He said that redline is fine. Never noticed any moisture in the oil but we have a pretty dry climate here.
 I'm also using redline in my 2000 softail, basically stock just because I buy one oil to fit all, LOL!
😆
Redline works for me.

I would think condensation is simply not getting the oil hot enough long enough, unless you get water in the vent via car wash or driving through high water.

My shockpruf heavy goes in and comes out looking like pepto bismol and I have no idea what the moisture content is.

I will never forget that, I was amaze in the condition the tranny was in when I tore it apart.  Still using the Shock Proof in the Baker 6 speed to today. no issues with condensation.

I was as amazed as you were when I read your post back in 2013. I was already using Shock Proof Heavy, and this just confirmed that my using it was a good idea.

I started using it in the Spring of 2010, when I bought a 2009 Ultra from Chandler Harley, which I think has a new name now. They suggested it to me when I went in to get an oil filter and some fluids. They had Shock Proof on display, one of their wrenches was at the parts counter and said in the dessert heat, that was the only way to go. And I've used it ever since. Even in cooler weather of Ohio and early summer humidity I never see any foam in the fluid.

I had Mark at R&D Motorsports do some performance modifications to my M8 trany and he had recommended Shock Proof. He's been working on bike transmissions for over 35 years.

[boooby1744]

I think any quality 75-140 will do in a 6 speed,modified or not.we all like what we like.

[Hilly13]

The only thing that can be of great concern with GL-5 oils is some of them are not syncro friendly, they can actually stuff them pretty quickly, also some are not good with white or yellow metal in general, be sure or be sad.
