Once differential fluid runs hot it stops protecting the ring and pinion and bearings, and in a limited-slip unit it breaks down the clutch packs and friction modifiers. PPE's cover is cast from heat-treated A356.0-T6 aluminum, adds 0.8 quart of fluid capacity, and uses half-inch external cooling fins to pull heat out of the oil when you tow or haul.\u003c\/p\u003e\n\u003cp\u003eInternal windage scrapers keep fluid moving over the gears without excess churning, which cuts heat buildup and parasitic loss. The scrapers and the vertical fins together form a cross-braced structure that spreads load and stands up to impacts. The fill plug sits at the factory fill height, and both plugs carry a high-temperature neodymium magnet to catch ferrous wear particles.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePart Number:\u003c\/strong\u003e 338052400 (Raw), 338052410 (Brushed), 338052420 (Black)\u003c\/p\u003e\n\u003ch6\u003eFeatures\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003eHeat-treated A356.0-T6 cast aluminum\u003c\/li\u003e\n\u003cli\u003eAdds 0.8 quart of fluid capacity\u003c\/li\u003e\n\u003cli\u003eHalf-inch external cooling fins for heat dissipation and impact resistance\u003c\/li\u003e\n\u003cli\u003eInternal windage scrapers reduce churning, heat and power loss\u003c\/li\u003e\n\u003cli\u003eFins and scrapers form a cross-braced structure\u003c\/li\u003e\n\u003cli\u003eMagnetic drain and fill plugs, fill plug at factory height\u003c\/li\u003e\n\u003cli\u003eAvailable in Raw, Brushed and Black finishes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch6\u003eNotes\u003c\/h6\u003e\n\u003cul\u003e\n\u003cli\u003eFits the Dana M315 12.4\" rear axle only.
