Ram 2500/3500 Standard Output parts.

pairs with: Intake

why this one: aFe is one of the largest diesel performance brands and offers both stainless and aluminized versions of this 5in DPF-back system with a choice of black or polished tips.

also carried: aFe Power Direct

pairs with: Intake, Intercooler

why this one: Banks explicitly markets its diesel tuners/exhaust/intakes as "emissions compliant performance parts" (bankspower.com), and this 409-stainless DPF-back system is purpose-fit to the current SRW-only 2019-2024 Cummins body with a documented backpressure reduction.

pairs with: Intake

why this one: Diamond Eye is a well-known DPF-back specialist and this dual-outlet 409-stainless kit is purpose-fit to the 2013-2018 Crew Cab Short Box 6.7L Cummins - one of the best-documented model/cab/bed combos for this era.

also carried: Diamond Eye Performance Direct

pairs with: Intake

why this one: MBRP is one of the most established diesel exhaust brands and this ARMOR Lite / Tour Profile kit is purpose-built for the pre-2013 (pre-DEF) 6.7L Cummins body style, in aluminized steel at a lower price point than stainless options.

pairs with: Intake

why this one: MBRP purpose-built this for the current-generation (2019+) 6.7L Cummins body; Tour Profile targets a quieter, daily-driver sound versus MBRP's louder Installer Series.

pairs with: Tire, Wheel

why this one: Extra oil volume and aluminum fins matter most if you tow heavy or run in hot country, because gear oil temperature is what kills rear differentials. It also has a drain plug, which the factory cover does not, so future gear oil changes stop being a messy job of pulling the whole cover off. The honest downside is that this does nothing for a truck that never tows, and it is a cosmetic upgrade at that point.

pairs with: Turbos, Tune, Fuel System

why this one: If you tow heavy or you are adding power parts, watching exhaust gas temperature is the single cheapest way to avoid an expensive mistake, and this reads it without drilling a probe into your exhaust manifold. One unit covers any 2008 or newer truck, so it moves with you. The honest downsides are that OBDII-derived readings update slightly slower than a dedicated hard-wired sensor, and at $419.00 it costs more than a basic single-function gauge that does one job well.

pairs with: Cat-Back, Turbos

why this one: This only makes sense for people who tow heavy in mountains. Your 2013-2024 Cummins already has a factory exhaust brake built into the variable-geometry turbo, so this is an addition to that rather than a fix for something missing, and BD claims up to 150 retarding horsepower from it. The honest downsides are steep: it is over a thousand dollars, it needs exhaust and electrical work, and a truck that tows flat or light will never notice the difference.

pairs with: Headlight, Light Bar

why this one: Fog pocket lights are the cheapest real lighting upgrade because there is no cutting, no aftermarket switch and no bumper drilling, and using the factory fog circuit keeps it simple. Baja Designs rates these at 3,162 raw lumens each with an IP69K waterproof rating. Two honest catches: this kit is listed for the Big Horn trim fog pocket, and other trims need Mopar bracket or bezel parts to fit, and the listed price is per light pod, so a matched pair costs roughly double.

pairs with: Turbos, Tune

why this one: This is a drop-in replacement for the factory in-tank module, so unlike an external frame-mounted lift pump kit there is no drilling, no extra fuel lines, and nothing hanging under the truck to catch road debris. Fleece rates it to support up to 800 hp. The honest downside is that a stock or lightly modified truck will never use that headroom, and you still have to drop the fuel tank to install it, which is the part most people underestimate.

pairs with: Turbos, Tune

why this one: Pick this one only if your truck came with the 50-gallon tank option, because the standard-tank pump physically will not seal in it. Fleece rates it to support up to 800 hp including dual CP3 setups. The downside is the same as the standard version: it costs real money for headroom a stock truck does not need, and the tank has to come down to fit it.

pairs with: Fog Light, Light Bar

why this one: If your truck came with the base halogen or LED reflector headlights, this is a genuine night-driving upgrade rather than just a styling one, and AlphaRex states the beam meets DOT FMVSS108 and SAE cutoff requirements, which cheap import housings usually do not. The honest downsides are the price, which is the highest of any lighting part on this platform, and that trucks already fitted with factory LED projector headlights need an extra converter that AlphaRex charges $65 for on top.

pairs with: Light Bar / A-pillar mount

why this one: Morimoto is a well-established LED lighting brand and this XB Evo assembly is purpose-built for the 2009-2018 Dodge Ram HD (2500/3500) body style specifically, not a universal-fit part.

pairs with: Cat-Back

why this one: Banks specifically engineered this to fix a factory grid-heater design issue (loose bolts that can cause engine damage) while improving airflow 88.3% over stock - a genuinely different value proposition than a standard cold air intake for this era truck.

pairs with: Cat-Back

why this one: Banks purpose-built this enclosed-housing intake for the SCR/DEF-era (2013-2018) 6.7L Cummins, offered in oiled or dry filter media.

pairs with: Cat-Back

why this one: S&B's fully enclosed airbox isolates the filter from engine-bay heat, and this is their purpose-built kit for the current (2019-2024) 6.7L Cummins.

pairs with: Cat-Back

why this one: This fills the gap for the 2013-2018 Cummins, which sits between the two S&B kits already listed here. S&B publishes real bench numbers for it, roughly 55% more airflow at 99.55% filtration on the cotton filter, and you can pick oiled cotton or dry media at the same price. The honest downside is that S&B publishes no horsepower claim at all for this kit, so treat any specific hp figure you see quoted elsewhere as marketing rather than measurement.

also carried: Performance Truck Products

pairs with: Intake, Cat-Back

why this one: Banks specifically replaces the factory MOPAR boost tube (52014735AB) with a constant 3.5in diameter tube design, a direct-fit upgrade rather than a full intercooler swap.

pairs with: Tire, Wheel

why this one: This is the cheapest of the three common Ram HD steering fixes and it addresses a completely different root cause than the other two: frame and box flex rather than worn joints. That makes it the right first step if your steering feels vague but a shop found no play in the linkage. The honest downsides are that it replaces nothing, so it will not help a truck with worn joints, and it is 4WD only.

also carried: Diesel Power Products, Performance Truck Products

pairs with: Tire, Wheel

why this one: Most cheap leveling kits are just a spacer stacked on the factory spring, which raises the truck but leaves the stock shock working outside its designed range and usually rides worse. Carli replaces the springs and valves the shocks to match, so ride quality typically improves rather than degrades. The honest downsides are cost, this is several times a spacer kit, and that it is Ram 2500 4x4 diesel only because the 3500 uses a leaf-spring rear and needs a different system.

pairs with: Tire, Wheel

why this one: The drag link is the single most common wear point in the 4th and 5th gen Ram HD front end, so if your steering has gone loose this is usually the actual worn part rather than the stabilizer. Kryptonite backs it with a lifetime warranty to the original purchaser. The honest downsides are the price for one link and the fact that replacing it alone will not fix play that is coming from the tie rod, ball joints or track bar, so diagnose before you buy.

also carried: Diesel Power Products

pairs with: Tire, Wheel

why this one: A dual stabilizer treats the symptom of front-end shake rather than the cause, so it is the right buy only after your drag link, tie rod and track bar are known good. Two things catch people out on this specific kit: the shocks are NOT included, so budget for a pair on top of the $399.99, and Kryptonite states it will not clear stock wheels, with a 5.5in maximum backspacing for 285-wide tires. Check your wheels before ordering.

pairs with: Wheel, Tire

why this one: ReadyLift's SST2.1 pairs monotube front struts with piggyback-reservoir rear shocks (3 tuning positions) and is explicitly engineered for the Standard Output diesel motor at up to a 35in tire.

pairs with: Suspension lift kit, Wheel, Tire

why this one: This kit is explicitly built to correct geometry on 4-6in lifted 2019+ Ram 2500/3500 trucks, complementing a lift kit in that height range from ReadyLift or another brand.

pairs with: Wheel

why this one: LT285/70R17 is a very common upgrade size for Ram 2500/3500 (close to factory-optional sizing on many trims) and this listing has a confirmed current price.

pairs with: Wheel

why this one: This specific size (LT275/65R18) is Load Range E, rated for heavier GVWR duty-cycle use appropriate to a 2500/3500, and is a size Nitto explicitly lists among its "popular truck and 4x4 fitments."

pairs with: Tune, Fuel System

why this one: The important thing here is that it keeps every factory turbo function, including the exhaust brake and the cold-weather warm-up cycle, which cheap drop-in turbos often break. Fleece also lists CARB Executive Order D-834-2 for it, so it is a 50-state street legal part rather than race-use-only. The honest downsides are the price and that Fleece publishes no hp or torque number for it, so anyone quoting you a specific gain is guessing.

pairs with: Tire, Suspension

why this one: Fuel Off-Road explicitly lists an 8x165.1 bolt-pattern option for this wheel across 18in and 20in sizes, confirmed sized/priced for Ram 2500/3500 HD applications.
