KC Cummander Turbo 302296 / 302662 - 63mm Billet - 600-650 HP

The KC Cummander turbo - part numbers 302296 and 302662 - is a 100% drop-in ready performance upgrade for Cummins-powered trucks that need real power gains without giving up towability. Built around a 63mm billet compressor wheel with extended tips, a high flow turbine wheel, and a ported anti-surge racing cover, the Cummander is rated for 600-650 hp - enough headroom for a built or tuned tow rig that needs lower EGTs under sustained load. This is a drop-in upgrade, not a stock-spec replacement; if factory-output restoration is the goal, a stock-replacement turbo is the correct path.

Built for the Tow Rig That Needs More

The KC Cummander 302296 / 302662 is the right call when your Cummins build has grown past what a stock turbo can support - but you still pull a fifth wheel or heavy trailer and need the VNT actuator's quick spool-up on every haul. At 600-650 hp, the Cummander delivers real performance headroom while the billet 63mm compressor, high flow turbine, and ported anti-surge racing cover work together to keep EGTs lower under sustained tow loads. The journal bearing design is built to handle the heat cycles and load variation a daily-driven tow truck generates.

Buy the Cummander for power and EGT margin on a modified build. Stay with a stock-replacement turbo if factory output and unmodified behavior are the goal - this is not the correct turbo for a stock-spec rebuild.

Confirm your part number with KC Turbos and this is the right turbo to add to your build.

What the 63mm Billet Compressor Changes

The billet compressor wheel with extended tips is the core upgrade over a stock-replacement turbo. Extended tips move more air at higher efficiency than a standard cast wheel, which translates to lower EGTs under tow loads and more top-end headroom on a tuned Cummins. The ported anti-surge racing cover keeps airflow stable at partial throttle - the kind of transition a loaded tow truck sees constantly when grade and throttle position are changing.

The journal bearing design suits street, tow, and daily-driven performance applications well. It is oil-fed, field-proven, and matched to the thermal cycles a working Cummins tow rig generates over time.

Exhaust Brake Compatibility - Verify Before Ordering

Brake retention comes down to two factors: whether your truck's calibration is configured for it, and whether your brake brand clears this turbo housing. If the exhaust brake is non-negotiable for your application, contact KC Turbos directly to verify compatibility before placing the order.

If your power goals, build level, and delivery address match above, proceed with the correct part number for your application.

Avoid These Common Mistakes

• Ordering for a stock-power rebuild - the Cummander is a 600-650 hp upgrade turbo, not a factory-spec option.
• Skipping exhaust brake verification - some brands conflict with this housing; confirm brand and calibration first.
• Not confirming which part number fits your application - verify 302296 vs 302662 with KC Turbos before ordering.
• Shipping to a CA or CO address - orders to California or Colorado cannot be processed without an eligible out-of-state address.

Before You Order - Final Checks

• Part number confirmed - 302296 or 302662 - for your specific Cummins year and application.
• Build level supports 600-650 hp - fueling, injectors, and tune are aligned with this power range.
• Exhaust brake brand and calibration confirmed compatible with KC Turbos (if applicable).
• Delivery address is not in CA or CO.

For a Cummins build that needs 600-650 hp, lower EGTs under tow, and a true drop-in fit, the KC Cummander is the correct upgrade turbo to order.
