Pros

It has the friction additive. Works perfectly in the limited slip rear of my '15 ram 1500. Rp is what i used in both of the diffs and gearbox.

No complaints here. Royal purple is one of the best companies. All is perfect. Does the job.

Product is great 7se their motor oil. It's gear oil, should be good to go. I expect it to be as good as royal purples reputation.
