1000 Series Automatic Transmission without optional 2nd
alternator.Notes:  This kit is for
Classic 6.6L Duramax vehicles without optional 2nd alternator. Customer
vehicles with the 2nd alternator, will have to fabricate their own mounting
for the compressor. All these kits are for vehicles with factory exhaust
systems. Vehicles with aftermarket 4” O.D. Exhaust systems will need 2
adapters : C11342. Air Actuated – Comes with Air Tank, Hose and
Accessories.Pacbrake’s InLineMount 4” PRXB Exhaust Brake KitPRXB offers
the highest braking power to lowest price ratio available. Pacbrake’s
flagship product is the unquestioned leader in the supplemental brake
industry. It has changed the way people think about exhaust brakes by
providing performance, safety and durability that is unmatched by any other
exhaust brake on the market.PRXB FeaturesThe spring controlled pressure
regulated mechanism on the exhaust brakes protects against engine
overpressurePacbrake exhaust brakes are designed specifically for individual
engine applications to maximize performance and reliability. They are not a
one size fits all compromiseWhen the brake is deactivated, exhaust flow is
unrestricted and won’t interfere with power output Patented 90 degree
Non-contacting Butterfly Valve is specially engineered to maximise
backpressure while preventing seizingThe brakes use industry exclusive Arcor
nitride coating on housing and components which increases resistance to wear
and corrosion while strengthening the exhaust brake and adding
lubricityPrecision machined surfaces on the exhaust brake eliminate the need
for troublesome gaskets and risk of leakageThe brakes have hard anodized
aluminum and stainless steel body and shaft with high performance
sealsMaintenance is as simple as using the exhaust brake on a regular basis
and periodically applying Superlube (Pacbrake’s multi-purpose heat
resistant lubricant which helps to prevent rust and corrosion)Withstands
extremely high exhaust temperaturesCompliant with latest emission
regulationsSevere duty & military approvedPRXB BenefiTsDelivers the
strongest braking horsepower, greatest speed reductions & shortest
stopping distances possible without the use of service brakesMaintains
optimum retarding performance by maximizing the exhaust backpressure
throughout the entire operating RPM rangeDelivers maximum exhaust pressure
(braking) as low as 1200 RPM through to the maximum allowable engine
RPMProvides increased performance and peace of mind with technology that
