PACBRAKE C40070 INLINEMOUNT 4 IN PRXB HP EXHAUST BRAKE FOR GMC 06-07 GM 6.6L DURAMAX (AUTO)

Enhance braking efficiency and drive with confidence using the PACBRAKE C40070 INLINEMOUNT 4 IN PRXB High Performance Exhaust Brake, expertly crafted for GMC Classic 2006-2007 models featuring the robust 6.6L Duramax engine, particularly those equipped with the Allison 1000 Series Automatic Transmission (excludes models with an optional second alternator).

This state-of-the-art exhaust brake represents a significant advancement in braking technology, delivering an impressive 50% more braking power at lower RPMs. Operating optimally within the 1400-1800 RPM range, it ensures a superior holdback compared to standard external brakes, which enhances safety while driving, especially in challenging conditions.

The intelligent spring-controlled pressure-regulated mechanism protects your engine from potential overpressure, ensuring longevity and performance. The PACBRAKE is meticulously designed for specific engine applications, eliminating the drawbacks of a one-size-fits-all system. When deactivated, the exhaust brake permits unrestricted flow, preserving your vehicle's power output.

A key innovation is the patented 90-degree Non-contacting Butterfly Valve, which optimizes backpressure while preventing common issues such as valve seizure. Built to withstand the test of time, the brake features an industry-exclusive Arcor nitride coating for enhanced wear and corrosion resistance, coupled with precision-machined surfaces that eliminate the need for gaskets, minimizing leakage risks.

Constructed from hard-anodized aluminum and stainless steel, paired with high-performance seals, this exhaust brake promises durability and reliability. Minimal maintenance is required—simply use the exhaust brake regularly and apply Superlube periodically for rust prevention.

Each PACBRAKE kit includes the exhaust brake, necessary controllers, and an Onboard Air Kit with all essential components for straightforward installation. Experience exceptional braking power and redefined performance with the PACBRAKE C40070 INLINEMOUNT exhaust brake for your GMC 6.6L Duramax engine.
