ARBs Air Locker Differential Spreader is a professional automotive tool that no differential installer should be without. Most common Salisbury style axle assemblies (e.g., Dana Spicer model 44) require the use of a differential spreader in order to achieve the required carrier bearing pre-load during set-up. Stretching the housing casting (or pumpkin) open by sufficient enough force as to allow extra shim to be added to create the pre-load is the method that the OEM manufactures endorse, and most manufacture's have included special spreader sockets in the housing for exactly this purpose. Insufficient pre-load can result in bearing failure, or ring and pinion failure on any differential, and possible oil/air leakage issues in an Air Locker Differential. As a part of ARBs Air Locker Tools range of differential service/installation equipment, this specialty tool offers an easy, quick and highly effective way of pre-loading these axles.Shipping Notes

Great stuff for my mercury motor. Did the oil change myself and saved lots of money from what the dealer charges.

Good quality good price.
At under $10/qt for high quality marine full synthetic, this is one of the best deals on Amazon. Other marine oils are upwards of $20/qt where I live and having twin outboards that require a total of 8.5qts each every change, that is a real savings. The other great thing about this oil is it’s packaging. The shape of the container and the pull out spout make it easy to pour. I don’t need to use a funnel with these and I didn’t spill a drop.

High quality oil
Liquid moly oil is great stuff. I bought this for my Honda 9.9 outboard. I’m sure non marine grade oil would have been fine, but for the price and quality of this oil why not use it.
