Great performer with your Severe Gear Synyhetic Lube. My diffrrrnyial is smooth, quieter and cooler than the stock GM Lubricants.

Everything works great

I add this to the 75w-140 gear oil that goes into the 2014 Ram1500 every 50,000 mile service. Also use it in the Jeep JKU along with Amsoil 75w90. Despite Amsoil saying their gear oil already has a posi additive. Doesn’t hurt to play it safe, as Mopar calls out for the use of a posi additive.

I always add a tube of Slip lock with every lube change in my Jeep, Ram, and my SRT Challenger. Works as advertised with limited slip differentials.

After years of rear diff. chatter in my 2003 Ford Ranger FX 4X4, Slip Lock, along with Amsoil 75w140 gear oil, the chatter stopped!! (performed a complete drain and re-fill)

Works Great.

Even though the Amsoil Severe Gear Gear Oil comes with a little Limited Slip additive. I wanted to make sure my rear diff in my 2013 Tacoma doesn't have the chatter. This Slip lock works well in my Tacoma.

Amsoil has been always #1 in my book. Love the easy squeeze packing.

I have tried two different suppliers for friction modifiers on my stock Jeep. The only product that works is the factory additive from Jeep Chrysler. Even then it’s only good for about 40K miles. This is a very short wheelbase vehicle that gets a lot of on off and windy roads. I have owned it for 22 years and 265K miles.

I must if you have a Chrysler rear end with a limited slip unit from the factory, keep things quiet and working correctly

Good product great idea

Just added when changing differential oil. Was impressed that Amsoil oil finder suggested using as required by manufacturers.

Years ago I bought a 1991 Nissan Pathfinder 4x4 and changed the rear differential fluid. I had metal noise chatter. Found out I needed a slip lock fluid Added Amsoil and within 1 day of driving around town a couple of times, problem fixed. I change the rear differential fluid every 50k miles and always add the Amsoil Slip Lock.

Works great with rear diff

Added a Banks diff cover. Upgraded to Amsoil 75-90 and the slip lock.

Used this on my 2014 Jeep Grand Cherokee SRT with 50k miles along with Amsoil 75W-90 severe gear oil in the rear differential. After an over 1k mile road trip, my truck is nice and smooth. Thanks Amsoil for your superior products!!! Customer for life

I add this to my CTSV, along with severe gear 75w90. Helps keep the whining down

Added this with Amsoil severe gear 75-90 oil no slip silent and smooth . Thanks again Amsoil .

My '92 Alfa Romeo Spider had the typical grind with 1st to 2nd upshifts, all upshift needed to be slow, and all downshifts were nearly impossible without a terrible grinding. I knew the lube specifications for the Alfa transmission are important and expected the last transmission service was not done with the right gear lube. I added a 4 oz tube of slip lock to the tranny and now the synchros work like a charm. No grind on any upshift and even quick downshifts are smooth, thanks to Slip Lock.

No issues since I have been using it.
