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.

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 Protection

buy at Walmartinstall
20-30 minutes
pairs with: Floor Mats, Bed Lighting
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.

buy at AutoZoneinstall
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.

estimate pending research
install
Not published for this specific SKU (Banks cites ~1.5 hrs for the related 2017-2019 SKU; not confirmed identical for this one - not assumed)
pairs with: Intake, Suspension
number source
A 5-inch stainless steel exhaust system that replaces everything from the diesel particulate filter (DPF) back, improving flow versus the stock 4-inch system while leaving the DPF, catalyst, and DEF/SCR system completely stock.
why this one: This is the only true 5-inch DPF-back system Banks publishes for the 2024-2026 L5P, and its patented Exhaust Pressure Control Module (U.S. Patent 12618353) is a documented, SKU-specific feature (prevents false power-derate codes) rather than a generic pipe swap.

pairs with: Intake, Suspension
number source
A 5-inch stainless steel DPF-back exhaust with Banks patented SideKick tip design, for Single Rear Wheel 2020-2022 L5P trucks.
why this one: Banks specific claim of 89% less backpressure at the DPF and a 15% exhaust-temperature reduction during regen is sourced directly to this SKUs own product page, not a generic series-wide number.

Approximately 1.5 hours per Banks own install-time estimate; owners manual and install video included
pairs with: Intake, Suspension
number source
A 5-inch stainless steel DPF-back exhaust with a patented obround slash-cut tip, covering all 2017-2019 L5P cab/bed configurations including dually (DRW) models.
why this one: Unlike the 2020-2022/2024-2026 SKUs, this one explicitly covers DCSB/DCLB/CCSB/CCLB configurations AND dually (SRW+DRW) models per Banks own fitment table - the broadest single-SKU coverage found for any year range this session, and compatible with stock/aftermarket fifth wheels and airbags per the same page.

A 5-inch stainless steel DPF-back exhaust with SideKick tip, covering 2011-2015 Silverado/Sierra 2500/3500 (all cab/bed configs except Single Cab Long Bed) plus 2016 2500 only.
why this one: This single SKU is the only Banks DPF-back option found spanning both the GMT900 (2011-2014) and K2 (2015-2016) HD chassis generations for the same LML engine - Banks own fitment table does not split by chassis, only by cab/bed config and a 2016-3500-specific caveat, which is noted rather than assumed away.

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.
why this one: 66,000 reviews and it does the one job most people need. Amazon runs about ten dollars under the manufacturer here, which makes the price comparison on the page honest and useful.

why this one: The plus model is the one that works on iPhone as well as Android, so nobody ends up with something that will not talk to their phone.

Head studs replace the factory head bolts that clamp the cylinder heads to the engine block. Studs pull straighter and hold more clamping force than bolts, which keeps the head gasket sealed when cylinder pressure climbs.
why this one: This is the standard answer on a Duramax that has been tuned or turned up, because the factory torque-to-yield bolts start letting the heads lift and push gaskets once boost climbs. One kit covers 2001-2016 in ARP2000 material rated at 220,000 psi tensile. The downside is brutal and worth saying plainly: the cylinder heads have to come off to fit them, so this is a shop job measured in days, and the smart time to do it is when the heads are already off for something else.
