Skid plates and armor sit under or alongside the truck to take hits that would otherwise land on the oil pan, fuel tank or rockers. This one is the Chassis Unlimited 2019-2025 RAM 2500/3500/POWERWAGON ROCK SLIDERS, listed to fit the 2019-2025 Ram 2500/3500. The listing describes it as bolt-on, direct fit, stainless steel.
why this one: Only worth the weight if you actually leave pavement. Check what the plate covers before assuming it covers everything. SDHQ Offroad lists it at $2759.99, and the fitment above is what the listing itself states, not a guess.

Bed Lighting

install
~30-45 min (peel-and-stick strips + wiring to 12V/fuse box)
pairs with: Tonneau covers/bed liners and cargo tie-downs; other 12V accessory-circuit add-ons (backup camera, trailer wiring)
number source
Two 60 inch light strips that stick under the rails of your truck bed so you can see what you are doing after dark. The kit comes with the on/off switch, a blade fuse, and a splitter so both strips run off one wire. Universal fit, meaning it is not cut for one truck, it works in any bed.
why this one: Cheapest thing on this list that solves a real problem. A lot of bed light kits leave out the switch or the fuse and you end up buying parts twice. This one has both.
also carried: eBay
install
~45-60 min (peel-and-stick strips + wiring to 12V/fuse box, 3 strips)
pairs with: Cargo bed dividers/tie-down kits and tonneau covers, and other plug-in 12V lighting accessories (rock lights, tailgate light bars)
number source
Same idea as the two strip kit with a third strip added. On a long bed, two strips leave a dark spot in the middle and the third strip fills it. Universal fit, it is not cut for one truck.
why this one: Buy this one instead of the two strip kit if you have a long bed. About eight dollars more for the extra light.

Bed covers, liners and mats keep the bed dry and stop cargo from chewing up the paint. This one is the Addictive Desert Designs 2019-2026 Ram HD 2500/3500 Long Bed Side Molle Panels Driver Side Addictive Desert Designs, listed to fit the 2019-2026 Ram 2500/3500. The listing describes it as bolt-on, powder coated, made in the USA.
why this one: Measure your bed length before buying. Bed covers are the most commonly returned truck part because of a wrong bed size. Apollo Off Road lists it at $598.98, and the fitment above is what the listing itself states, not a guess.

requires: trimming to fit. BDK ships this mat at 60 by 19.5 inches as a universal trim-to-fit design, so on a midsize tailgate it needs cutting down with scissors before it will sit right. Mounting hardware is included and fitting it involves drilling.
number source
A thick rubber mat that covers the inside face of your tailgate. That is the surface that actually gets scratched when you slide things in and out of the bed. Universal, so you trim it with scissors and screw it down.
why this one: The only bed protection product we found under fifty dollars. A real full length bed mat starts around $115 because it is one big molded piece cut to a specific bed length. This one protects the part that takes the most abuse.
install
20-30 minutes
pairs with: Floor Mats, Bed Lighting
requires: trimming to fit, and a bare metal tailgate. Cat ships this mat at 62 by 21 inches with cut guides marked at 17x54, 19x59, 20x60 and 21x62 inches, so it covers full-size and midsize gates but nearly always needs cutting with scissors or a utility knife. Cat states it is made for bare metal tailgates and is not compatible with plastic tailgates. Mounting hardware is included and fitting it involves drilling.
number source
A thicker, tougher version of the basic tailgate mat. It covers the inside face of the tailgate so loading and unloading does not chew up the paint. Universal, trim it to fit.
why this one: Heavier duty than the cheap mat and a brand name people recognize, which helps it sell. AutoZone runs about sixteen dollars over Amazon, so the comparison favors us.

A DPF-back exhaust is the diesel equivalent of a cat-back: it replaces everything from the factory diesel particulate filter rearward while leaving the DPF and catalyst fully in place, so it stays emissions-legal.

A DPF-back exhaust is the diesel equivalent of a cat-back: it replaces everything from the factory diesel particulate filter rearward while leaving the DPF and catalyst fully in place, so it stays emissions-legal.
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.

A handheld tool that plugs into the port under your dash and tells you why the check engine light came on. It shows a code, explains what the code means on its own screen, and can turn the light off. No batteries and no phone needed. Works on any 1996 or newer vehicle, which is what OBD2 means.

number source
The differential cover is the plate bolted to the back of your rear axle housing that holds the gear oil in. This is a thick cast aluminum replacement for the stamped steel factory cover, and it holds about three quarters of a quart more oil.
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.

protects power, no gain
install
~30-45 min (reasoned estimate; plugs into the OBDII port, most of the time is routing the cable and mounting the pod)
pairs with: Turbos, Tune, Fuel System
requires: Fits ALL 2008+ OBDII CAN bus vehicles; not year-specific to Ram. Note this covers 2008 model year onward, so 2007.5 trucks are outside the stated range. Standard 52mm (2-1/16in) gauge mount, pod not included.
number source
A digital gauge that plugs into your truck OBDII port and shows engine data the factory dash never displays, things like turbo boost pressure, exhaust gas temperature and transmission temperature. The DataMonster version also records up to 100 values at once to a microSD card so you can look at what happened after a tow.
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.

install
~3-4 hrs (reasoned estimate; exhaust work plus electrical, shop job for most owners)
pairs with: Cat-Back, Turbos
requires: 2013-2024 Ram 2500/3500 6.7L Cummins per BD product title. NOTE: these trucks already have a factory VGT turbo exhaust brake; this is a supplemental inline unit. BD does not publish a part number on this product page.
number source
An exhaust brake restricts exhaust flow on the way out so the engine has to work against that back pressure, which slows the truck without touching the service brakes. This is an inline butterfly valve that clamps into the exhaust and is controlled electronically, so there is no air compressor or air lines to plumb.
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.
