Max-Gear is an extremely tough, high-performance GL-5 gear oil designed to provide maximum protection under heavy-duty gearboxes while increasing power through the transmission. Max-Gear outperforms other GL-5 oils as it combines the highest quality synthetic oils with Synslide ™, Royal Purple's proprietary synthetic oil film that is so strong and tough it won't be squeezed out of the pressure zone. Max-Gear virtually eliminates gearbox and bearing wear even in extremely difficult "film crushing" conditions caused by very heavy loads, sudden shock loads and low revs. The slippery synthetic molecules not only reduce wear and friction, but significantly increase the fluidity and lubricity of Max-Gear at low temperatures, making it the ideal product for vehicles operating in cold climates. Max-Gear ensures better operation of the gearbox, with less noise, lower temperatures and longer times, without revisions and without corrosion, both for ferrous and non-ferrous metals.
