Increase differential cooling, improve gear protection and strengthen your front driveline with the PPE GM 2500 HD Cast Aluminium Front Differential Cover. Designed for GM 2500HD and 3500HD models equipped with the 9.25" IFS front differential, this premium upgrade increases oil capacity while replacing the factory pressed-steel cover with a heavy-duty cast aluminium alternative.

 

The PPE GM 2500 HD Cast Aluminium Front Differential Cover has been engineered to improve cooling performance, increase differential oil capacity and provide superior protection for the front differential housing.

Whether you're towing heavy caravans, travelling remote tracks or working your Silverado in demanding conditions, differential temperatures can increase significantly under sustained load. The PPE cover increases differential oil capacity by approximately ¾ quart (0.7 litres) while significantly improving heat dissipation through its extensive internal and external cooling fin design.

Manufactured from premium cast aluminium, the PPE cover provides substantially greater rigidity than the factory pressed-steel cover while helping protect the differential housing from impacts caused by rocks, road debris and off-road obstacles.

To further improve reliability, PPE incorporates a high-powered Neodymium magnetic fill plug that captures ferrous wear particles before they can circulate through bearings and gears. A dedicated 1/8" NPT temperature port also allows installation of an optional differential temperature sender.

Key Features:

  • Heavy-duty cast aluminium construction.
  • Durable black powder-coated finish.
  • Suits GM 9.25" IFS front differential.
  • Approx. ¾ quart (0.7L) additional oil capacity.
  • Extensive internal and external cooling fins.
  • Increased housing rigidity.
  • Improved underbody protection compared to the factory pressed-steel cover.
  • High-powered Neodymium magnetic fill plug.
  • 1/8" NPT temperature sender port.
  • Reuses OEM gasket.
  • Zinc-plated mounting hardware.
  • Limited lifetime manufacturer warranty.

Why Upgrade?

The front differential works extremely hard on vehicles used for towing, off-road driving and heavy-duty applications.

The PPE differential cover helps by:

  • Increasing differential oil capacity.
  • Improving oil cooling.
  • Lowering operating temperatures.
  • Improving lubricant life.
  • Increasing housing strength.
  • Providing greater resistance to impacts from rocks and trail debris.
  • Capturing metallic wear particles before they circulate through the differential.

Ideal for:

  • Caravan towing.
  • Heavy towing.
  • Touring.
  • Off-road use.
  • Commercial vehicles.
  • Fleet applications.

Why We Recommend It:

At Garage76, we recommend upgrading differential protection on vehicles that regularly tow, tour or operate off-road.

The PPE Front Differential Cover increases oil capacity, improves cooling performance and provides a much stronger housing than the factory pressed-steel cover. Combined with magnetic filtration and improved serviceability, it's an excellent preventative upgrade for protecting expensive differential components in harsh Australian conditions.

DIESEL TUNING STAGES

WE OFFER THREE STAGES OF DIESEL PERFORMANCE PACKAGES

From a safe and reliable tune of your OEM ECU through to wild diesel performance upgrades, we've got 20+ years of diesel tuning under our belts and can tailor a package to suit your performance or touring needs.

STAGE ONE
(10-30% INCREASE*)

Our Stage One kits (vehicle depending) will always include an ECU remap and a tune on our in-house dyno. 
No two vehicles are the same and every diesel performance package we book spends time on our dyno.
  • G76 Custom ECU Remap

STAGE TWO
(30-50% INCREASE*)

Once you are looking to go beyond the performance of our basic Stage 1 Package, you will reach the limitations of your factory turbocharger. At this point a turbocharger upgrade will be required, along with appropriate upgrades to the exhaust, air intake system and intercooler. With these upgraded items we are able to squeeze more performance than a stock setup will ever provide.
  • G76 Custom ECU Remap

  • Upgraded Exhaust

  • Upgraded Snorkel & Airbox

  • Upgraded Turbocharger

  • Intercooler Upgrades Or Intercooler Fans

STAGE THREE
(50+% INCREASE*)

Looking for maximum GRUNT without compromising factory reliability? Our Stage Three Package is for you! This package will give you the ultimate in diesel performance, with massive gains available in power and torque. 
The main difference between our Stage Two and our Stage Three Package is the addition of high flow fuel injectors. In a diesel engine, more fuel = more power, provided you have the air to burn it! We also only have a small window of crankshaft rotation available to inject the fuel. High flow injectors allow us to increase the amount of fuel delivered to the engine during this window, resulting in huge gains in power and torque.
  • G76 Custom ECU Remap

  • Upgraded Exhaust

  • Upgraded Snorkel & Airbox

  • Upgraded Turbocharger

  • Intercooler Upgrades Or Intercooler Fans

  • High Flow Injectors

  • Upgraded Fuel Pumps

*power and torque numbers will differ between vehicle models and final diesel performance packages and tunes. Our increase numbers should be used as a guide only. Different vehicle makes will have variations in the packages we offer, not all packages come with intake cleans.
