About Slip Lock Differential Additive
Slip Lock Differential Additive for the listed differential treatment applications. Compare the current AMSOIL application information with your equipment’s service documentation before planning the job. Keep the product code ADATB-EA handy when reviewing package options or asking Jeff a question.
Before you choose
Confirm whether the axle requires a friction modifier and whether the selected gear oil already contains one. Follow the current product dosage and application instructions.
Does every differential require an additive?
No. Differential designs and lubricant formulations differ. Add a friction modifier only when the axle and lubricant guidance call for it.
