Questions & Answers

Can you tell me what viscosity this oil has?

For heavily-loaded moving vehicles, the film thickness is greater than an SAE 75W250, but the fluid friction is lower than 75W90* Typical performance racing applications include racing differentials and transmissions overloaded, problem gearboxes, Detroit Lockers and spools, and NHRA Top Fuel and Funny Car rear ends*br>Not recommended for most synchro applications due to the extreme slipperiness.

Viscosity, in terms of viscosity, how does this measure up? There is a specific number I need. ?

This film is thicker than an SAE 75W250, but has low fluid friction like an SAE Here is a screenshot of the manufacturer's website.

On my 2002 RoadKing Screaming Eagle I made a BIG MISTAKE when I changed the primary chain oil. I have added the REDLINTransFluidw/Shockproof option. How do I know if it's compatible?

The answer is no, I would think. In this case, there will be much greater thickness because the primary runs a 20w 50 while the red line would be somewhere around 75 90. If you want to be sure, call the local Indianapolis office rather than the HD office.

What is this score? It's There is no mention of this on their product pages. My definition of heavy is completely different from yours. ?

There are no viscosity ratings that I know of. Having followed the HDForums for several years, I decided to give it a try based on the overwhelmingly positive response from Harley fans. It is definitely improving the shifting on my '07 Road King, especially finding neutral at the start of second My '06 Wide Glide driver did not get as dramatic results as my 2005 and 2006 rider. Besides its high price and the fact that it stinks to high heaven when you drain it, my only complaint is its cost.

What transmission oil should I use on my Harley V-Twin? They are twins
5/5

I have a 2007 Harley Street Bob that includes the Redline Heavy Duty Shockproof. When you use this stuff, your transmission runs like silk. The oil has an in-depth lubricating capability that is different from other gear oils on the As a consequence, I was running Lucas and Royal Purple gear oil in my Harley tranny before I switched to Redline heavy duty shockproof. Although I enjoyed both of them, I won't go back to them after hearing and feeling the difference that Redline makes. It simply cannot be beaten. This book is highly recommended. It will bring your transmission to life by making it Using other gear oils is not advisable, and you should definitely not use synthetic gear oil In the transmission, there are three items. There's no point in buying that crap.

Fix the 6 Speed Harley
5/5

The noise that comes from first and fifth gears will be reduced if you have a Harley with a 6 speed from 2007 to 2010. The update is With the Red Line trans oil, the gear "whine" is no longer audible after about 1500 miles It is real. It's impossible for me to express how much I love Red Line products are the only lubes I will ever use on either my Harleys ever again.

The tires fit my heavily tracked Mustang GT just right
5/5

For a stock 8 to last 25 minutes of hot laps is quite a feat. The rear differential on the 8" solid axle is 8". A typical day for me includes four or five sessions. Heat is a lot of fun! Although I have a breather in my car, a different cooler does not help as much. This Red Line Heavyweight oil is designed to protect you from industrial damage, but it Despite the axle requiring 90w140, Heavyweight Shockproof oil flows well and has held up more efficiently than any other fluid, including Red Line yellow-colored 90w140 gear oil and Royal Purple heavy duty synthetic oil. you are going to use this product for heat applications that last for a long time, this is a great choice!.

Your transmission will shift like butter with this
5/5

I have been using Red Line oils in all 3 holes since about a couple of You will notice a noticeable difference in the smoothness and noise of your transmission after using this oil. This is what I say about all the oils from Red Line The sound you will hear and the feeling you will feel in your bike will be incredible. Do not hesitate, get this now.

A BIG ATTENTION TO EVERY HARLEY OWNER! OUR OIL WILL BE THE LAST ONE YOU WILL EVER PURCHASE
5/5

I am interested in a position in primary and secondary education. A HARLEY IS ONE OF THREE HARLEYS I OWN. Road King 2002, Dyna Wide Glide 2003, Street Glide Special 2020 131CI SE STG4 - all 2002's.
By now, N is no longer a mystery to be found. Is able to satisfy every request you make. A CLUTCH SLIP CAN NOT BE TOLERATED! I don't believe in bull. For all you Harley owners out there, this will be the only oil you'll ever need. If you have a transmission and primary oil, this should be the only one you rely on. For me, it is a matter of course. I am grateful for your time.

I've got it in red
4/5

Do not be scared by the color. There is a strong smell of gear oil coming from this deep red liquid. To change the tranny fluid on my '03 Road King, I used this product. The change becomes apparent as soon as the first test ride is completed. We have a quieter and smoother shifting experience. No need to look for neutral, it's right there. A whine at speed may be a little quieter than at slow speeds. This has only been run for a couple hundred miles with no problems so far.

For Harley, only the best is good enough
5/5

For Harley, only the best is good enough. The difference between this and having the garbage Syn3 in the bike is obvious to me. Buy with confidence.

There is a big difference between OEM oil and our Red Line #58204 gear oil is the only oil I will use for my FL transmissions
5/5

Shifting feels smoother and there is no noticeable change in the feeling of shifting up or down. As I have never experienced transmission noise, I can't say that it would help there. I am impressed with how smooth my shifts are using this product compared to the original.
