Unlock Maximum Power: The 5 Best Cummins Performance Kits from TruckTok with Fast Shipping

Diesel DIY mechanics demand maximum airflow and reduced exhaust restrictions for competition applications. Upgrading your CUMMINS requires precision-engineered components that directly replace factory bottlenecks. High-performance diesel engines suffer under the weight of restrictive factory emissions equipment, leading to elevated exhaust gas temperatures and carbon-choked intake manifolds. TruckTok provides the definitive selection of performance hardware and delete kits designed specifically for dedicated track and off-road rigs. The following kits represent the most effective mechanical upgrades for the 5.9L and 6.7L platforms.

Cummins Performance Kit Comparison

1. TruckTok 6.7L DPF Delete Bundle for Competition Track Use

Removing the factory diesel particulate filter (OEM part number 68035060AA) is a strict requirement for competition builds. The TruckTok 6.7L DPF Delete Bundle eliminates the restrictive honeycomb ceramic structure found in stock exhaust systems. This kit includes a straight-pipe section and the necessary tuning hardware to prevent the engine control module from triggering limp mode. By clearing the exhaust path, the engine expels spent gases rapidly, drastically lowering exhaust gas temperatures during high-load track events. Lower temperatures protect vital engine internals during sustained wide-open throttle applications. This modification is strictly for closed-course off-road and competition use only.

• Pipe diameter: 4-inch aluminized steel
• Limitation: Requires specialized ECM flashing; not suitable for vehicles operating on public roads.

2. TruckTok 6.7L EGR Cooler Delete Kit for Coolant Reroute

The factory exhaust gas recirculation system (OEM valve part number 68002433AC) routes hot, soot-laden exhaust back into the intake manifold. The TruckTok 6.7L EGR Cooler Delete Kit blocks this pathway entirely. Mechanics install this hardware to prevent heavy carbon buildup on the intake grid heater and engine valves. The kit features billet aluminum block-off plates and a high-flow coolant reroute hose, ensuring optimal engine temperatures and fluid circulation. Blocking the EGR flow maximizes the density of clean, cold air entering the combustion chamber for a more efficient burn. This kit is designated for off-road and competition use only.

• Material: CNC-machined billet aluminum block-off plates
• Limitation: Installation requires draining and bleeding the factory cooling system, adding significant labor time.

3. TruckTok 5.9L Cold Air Intake System for Airflow Enhancement

Upgrading the intake is the first mechanical step in maximizing combustion efficiency for the 5.9L platform. The TruckTok 5.9L Cold Air Intake System replaces the restrictive factory airbox and standard paper filter. It features a wide-diameter intake tube and a high-flow, washable filter element. This setup draws dense, cold air from outside the hot engine bay directly into the turbocharger compressor housing. More air volume allows the engine to burn fuel completely, generating higher boost pressures earlier in the RPM band and improving overall throttle response.

• Filter type: Oiled, multi-layer cotton gauze
• Limitation: Requires regular cleaning and re-oiling of the filter element to maintain proper filtration efficiency.

4. TruckTok 6.7L CCV Reroute Kit for Crankcase Pressure Relief

The closed crankcase ventilation system routes oil vapors back into the turbocharger, coating the compressor wheel and intercooler boots with heavy oil residue. The TruckTok 6.7L CCV Reroute Kit vents these gases directly to the atmosphere. Bypassing the factory CCV filter (OEM part number 68002433AB) prevents oil from pooling inside the intercooler, which can degrade silicone boots and reduce thermal efficiency over time. This kit includes a billet aluminum vent block and a heavy-duty oil-resistant routing hose to keep the intake tract completely dry. This modification is intended for off-road and competition use only.

• Hose specification: 3/4-inch oil-resistant synthetic rubber
• Limitation: Vents crankcase gases externally, which produces a noticeable oil smell around the vehicle exterior.

5. TruckTok 6.7L 4-Inch Downpipe Exhaust for Backpressure Reduction

Replacing the factory downpipe removes the primary bottleneck immediately aft of the turbocharger. The TruckTok 6.7L 4-Inch Downpipe Exhaust provides a smooth, mandrel-bent path for exhaust gases exiting the turbine housing. This direct replacement for the factory downpipe drops exhaust backpressure significantly. Lower backpressure allows the turbocharger to spool faster and operate more efficiently at peak boost. Eliminating this restriction is critical for managing heat on heavily fueled track trucks. This component is strictly for off-road and competition use only.

• Construction: Mandrel-bent 4-inch steel piping
• Limitation: Increased exhaust resonance and distinct turbo whistle in the cabin compared to the stock cast-iron pipe.

Frequently Asked Questions

Are DPF delete kits legal for street use?

No. Removing the factory emissions equipment is strictly prohibited for vehicles driven on public roads. These modifications are engineered exclusively for dedicated off-road vehicles and sanctioned competition track use.

What does an EGR delete do for a 6.7L Cummins?

An EGR delete blocks hot exhaust gases from re-entering the intake manifold. This prevents heavy carbon soot buildup on the intake valves and grid heater, ensuring the engine ingests only clean, dense air.

Do I need a tuner after installing a delete pipe?

Yes. Removing the factory exhaust filters will trigger diagnostic trouble codes and force the engine into limp mode. A specialized tuner recalibrates the engine control module to operate correctly without the missing sensors.

What is the OEM part number for the 6.7L Cummins CCV filter?

The factory closed crankcase ventilation filter for the 6.7L Cummins is typically Mopar OEM part number 68002433AB. A reroute kit bypasses this filter entirely to vent crankcase pressure externally.

How does a CCV reroute protect the intercooler?

The factory system routes oily crankcase vapors into the turbocharger compressor. Over time, this oil coats the inside of the intercooler and degrades silicone boots. Rerouting the system keeps the intake tract completely dry.

Will a 4-inch downpipe increase exhaust noise?

Yes. Replacing the thick cast-iron factory pipe and restrictive filters with a 4-inch steel downpipe increases exhaust volume. Drivers will notice a louder exhaust note and more pronounced turbocharger whistle in the cabin.

Can I install an EGR cooler delete without draining the coolant?

No. The factory EGR cooler integrates directly with the engine cooling system. You must drain the coolant before removing the cooler to prevent spills, then bleed the system properly after installing the reroute hose.

What is the benefit of a cold air intake on a 5.9L Cummins?

A performance intake replaces the restrictive factory airbox with a high-flow filter and larger diameter tubing. This supplies the turbocharger with a higher volume of cold, dense air, improving combustion efficiency and throttle response.

Do TruckTok performance kits require welding?

No. Most kits feature a direct bolt-on design. The exhaust pipes, block-off plates, and intake tubes are engineered to mount securely to factory flange locations using the provided clamps and heavy-duty hardware.

Why do competition trucks remove the catalytic converter?

Track vehicles require maximum exhaust flow to control extreme engine temperatures under heavy loads. Removing the restrictive catalytic converter lowers exhaust backpressure, allowing the turbocharger to spool faster and reducing overall thermal stress.

Conclusion

Maximizing the output of a diesel engine requires eliminating factory airflow restrictions and managing extreme heat. TruckTok performance kits provide the exact mechanical solutions needed to optimize exhaust flow, prevent carbon buildup, and relieve crankcase pressure. For DIY mechanics building dedicated off-road and competition vehicles, installing the right hardware is non-negotiable.
