The Hemi Under a Ram's Hood Is the Same One Under a Challenger's

A Ram 1500 catch can and a Dodge Challenger catch can start from the same architecture, because the 5.7L and 6.4L Hemi V8 shows up in the truck and the muscle car with the same crankcase ventilation path. Mopar built one V8 platform and dropped it into a truck line and a performance coupe; a Mopar catch can sized for that architecture works across both without reinventing the hardware for each nameplate. Jeep runs the same Hemi in its own applications, too, so Wranglers and Grand Cherokees inherit the identical blow-by problem.

A Dodge Challenger oil catch can pulling duty behind a Hellcat's supercharger deals with crankcase pressure a naturally aspirated 5.7 never sees, because boost pushes extra air past the rings under load, and that added pressure needs somewhere to go. We size the supercharged Hemi catch can kit around the higher-pressure PCV draw rather than reusing the same valving that works fine on a stock 5.7.

Ram 1500 Catch Cans Designed for the Way You Work

Plenty of Ram 1500 work trucks spend more time idling at a job site than moving down a highway, and that idle time builds up its own crankcase moisture and blow-by even without a single mile of towing behind it. A Ram 1500 catch can address oil vapor regardless of how the truck is driven.

A Wrangler adds a variable that a truck or coupe never deals with: sustained off-camber angles on a rock ledge or a steep grade. Catch can baffling designed around occasional vibration doesn't necessarily hold oil in position when the vehicle sits tilted for minutes at a stretch, so the internal baffling in our Jeep applications accounts for that kind of sustained lean rather than just the bumps of daily driving.

Our oil catch cans page breaks down every configuration we build by engine platform, and the popular oil catch can kits page shows which builds our customers choose most often across the Hemi lineup. If you want a description of how the filtration process works before choosing a kit, our catch can explainer covers the basics.

Same Engine Architecture, Same Fix, No Matter the Badge

One catch can platform covers the 5.7 and 6.4 Hemi, no matter which body panel surrounds it, so you get hardware built around your actual engine instead of a universal shell borrowed from elsewhere.

Frequently Asked Questions About Dodge, Ram & Jeep Catch Cans

Do Hellcat and other supercharged Hemis need a different catch can than a naturally aspirated 5.7?

Boost raises crankcase pressure beyond what a naturally aspirated Hemi produces , so supercharged applications use valving sized for that higher pressure rather than the standard configuration for a stock 5.7L or 6.4L.

Does a Ram 1500 with the EcoDiesel need this catch can, or is it only for gas engines?

This kit is built for the gas Hemi. The EcoDiesel routes crankcase ventilation through its own separate system, so a gas-specific catch can isn't the correct fitment for that engine.

Will a catch can hold up on a Jeep that regularly sees steep off-road angles?

Our Jeep-specific hardware accounts for sustained off-camber positions rather than just vibration , since a Wrangler climbing a rock ledge or holding a steep grade keeps the can at an angle for much longer than a bump in the road does.
