TriaxSynergy Gear MAX 75W-140 GL-5, PAO Synthetic Long-Drain Axle, Differential Extreme Pressure Oil, Limited Slip Ready, 750,000 Mile Rating on Highway (1 Gal)

I got the old black bottles and said made in USA. I have no info on new ones but I was happy with my oil and price was excellent vs the big brands. LSD ready. I run it in my 03 dodge factory 9.25 posi with 410k miles. 0 issues, posi works great and chatter free.

Great value for the price, long life lubricant that outperforms the OEM version.

I love how sturdy the stuff looks. I have not driven my vehicle yet with. I am going to tomorrow. I got a trip to go on. I have to drive 3 hours out of my way. And I have to tow camper all the way to Arizona. From the east side of the usa Hopefully this stuff lasts up to the toughness that it needs to be. Thank you for the catalog. And I even put the sticker on my vehicle.

Just changed out my rear diff cover on my 06 f250 and decided to upgrade the oil also. This triax gear oil seems to be great stuff, good viscosity and seems to be keeping my gears happy. Packaging was nice and even the bottles looked nice. Not that looks matter but I was just impressed. They take some pride in their product. Safe to say i will turn to them in the future.

Great value compared to local parts store

Fast shipping. No issues!

Good gear oil but I did have to add about 3 to 4 ounces of modifier to my limited slip differential that calls for 8 ounces...I tried without adding any and had a little slip and chatted but it cleared up with just like 3 or 4 ounces of the modifier additive...since then it seams great...I did have a problem with shipping but it wasn't on there end it was the delivery people I think it was delivered to the wrong address cause I didn't get it and had to call Amazon and get it shipped again and it came to me the second time but this wasn't the company's fault they sent it out on time

Good product and price, good quality gear oil
