Would the 95 Isuzu 4x4 front differential benefit from this additive? I know the rear limited slip diff does!

No, unless it's a limited slip after market and specifies such. On the rear positive, too much would cause slippage between the plates. Just ad enough to stop the clanging. Too much would lesson the Limited slip .

Can this be used in redlline dct fluid that is used in a manual tranmission with lsd?

It was purchased for my son. I didn't use it. My son is a car mechanic, so I think it is a good product.

Would this help a 95 Isuzu front 4x4 differential? ...that chatters around corners on pavement?

Check your u-joints but if there ok. Let me know if it worked. Differential Gear oil is supposed to be replaced on a regular Preventative maintenance Schedule. I don’t know what the mileage is on your car is but it couldn’t hurt “unless your vehicle is not a LSD Diff.” Thanks!

do I need that for my 99 chevy express 1500 V8 with amsoil 80W90 together?

My chevy Silverado 2500HD ran better after adding a 4oz. can of Redline with the rear gear oil. There is also an additive for the transfer case GM put in during a service. I would double check before putting that in the transfer case. Keep on reading, you'll find the answer. Good Luck

Muy bueno

Este modificador de frucción me ha ido fantástico en el diferencial autoblocante trac lok de mi grand cherokee zj. Se han acabado los ruídos que tenía porque se enganchaban.los discos. Aunque tenía aceite 75W140 especial para autoblocante, no hacía bien su función. Saqué 110ml de aceite y lo sustituí por este botecito, y mano de santo. Si tienes ruídos o crujidos raros en el autoblocante, no dudes en ponerlo, serás feliz

Erfüllt seinen Zweck - Redline 80301

Habe den Zusatz beim Ölwechsel meinem Limited Slip Differential beigemischt wie vorgegeben. Die Menge der (überraschend kleinen) Flasche enstpricht genau der vorgeschriebenen Menge (118ml). Konnte bislang keine Probleme feststellen, es erfüllt seinen Zweck.
