XYZ Racing Hollow Rear Brake Kit — Hummer H2 (2003-2009)

The Hummer H2 tips the scales at close to 2,900kg before you add passengers, fuel or a trailer, and all of that mass loads onto a rear axle that the standard discs were never really sized to manage. Hard descents, repeated stops on a long motorway run, or towing on a hot day are exactly the conditions where the factory rears run out of thermal headroom and the pedal goes long. This XYZ Racing Hollow Rear Brake Kit is the answer to that specific problem on the 2003-2009 H2.

It is a larger-diameter rear setup built to absorb and shed the heat a vehicle this heavy generates under braking. Rather than chasing outright stopping distance alone, it targets the thing H2 owners actually complain about: brakes that work the first time and fade the third. Pad compound is selectable across Street, Sport and Racing, so the kit can be set up for a daily-driven truck, a towing rig, or harder repeated use.

What this brake kit does for your 2003-2009 Hummer H2

On a body-on-frame SUV this size, the gain you feel first is consistency. The larger rear rotor and increased pad area give the system more thermal mass, so the pedal stays firm through a sequence of stops instead of softening as the standard discs heat-soak. That matters most when the H2 is loaded or descending a long gradient, where rearward weight transfer puts real work through the back axle. Choosing the Racing pad compound sharpens initial bite and raises the fade threshold for owners who tow heavy or use the truck hard; the Sport compound steps up everyday bite, while the Street compound keeps noise and dust manageable for a road-driven H2. The result is braking you can lean on repeatedly without the creeping fade that the factory rear setup is known for.

About the Hollow rear brake kit

The Hollow rear kit is XYZ Racing’s heavy-vehicle rear upgrade, designed around the simple reality that stopping power on a large SUV is a heat-management problem first. The kit uprates the rear disc and caliper assembly over standard to add the thermal capacity a 2,900kg platform demands, with the two-piece floating rotor and mounting hardware sized as a direct-fit package for the H2’s rear axle. The hollow-bodied caliper is standard across the range, and the rotor sheds heat faster than the solid factory casting. Pad compound is offered in three grades: Street for quiet, low-dust manners, Sport for a firmer everyday bite and more heat range, and Racing for the highest fade resistance under sustained load. Discs come drilled or slotted at the same price. The caliper finish is fully specifiable, with Red, Yellow, Gold, Black and Anodized Black at no extra cost, plus premium polished-forged Titanium, Polished Gold and Polished Silver, candy Teal, Blue, Red and Orange, or any Pantone shade as a custom colour. It is a rear-axle kit, intended to pair with a matched front upgrade rather than to carry the whole job alone.
