Arrowmax O-ring grease
Coming from Arrowmax is the new O-ring grease. Specially formulated to prevent damages to the O-rings of shock absorbers and gear differentials the lube makes for super-smooth shock and diff action. The grease will keep silicone seals from swelling while also greatly reducing leaking issues and it is usable for on-road and off-road applications alike.
