Silverado and Sierra 2500HD and 3500HD Running Boards: Year Splits That Differ From the 1500

Find your year and cab first. Everything here is what listing titles and the maker documents we name state, read on November 2, 2026. The 1500 has its own page at Silverado running boards. The GMC 1500 is on Sierra running boards.

Fit sheetOur pick: Silverado and Sierra crewAd

Tyger Auto

Tyger Rider 3.5" (2019+ GM)

A 3.5-inch rail whose title names the Silverado and Sierra years, the HD split and the cab.

Why here: The title separates the 1500 years from the HD years, and its part number leads to a sheet we could read.

Why it makes the list

• The part number in the title (TG-SS2C35068) ties the listing to Tyger's own instruction sheet
• That sheet bolts 8 brackets to threaded holes behind plugs in the rocker area and has no drilling step
• Title separates the 1500 years from the 2500/3500HD years

Watch out for

• 3.5 inches wide per the title, narrower than the 6-inch boards
• No weight rating in the title, so none is printed here
• The title does not mention the 2019 LD/Limited; a sister Tyger listing groups that truck with the older body, so check before ordering

Best for: Crew cab owners on the 2019-up GM full-size who want a rail with a readable install sheet.

The split that catches HD owners

On the 1500, listings break between 2018 and 2019. On the HD, they break between 2019 and 2020. So one model year sits on opposite sides of the line, depending on your truck.

Westin's table draws the same line: part 29-23725 runs 2007-2019 on the HD Crew Cab, and 29-24135 starts at 2020. It is not universal, though. The Auto Dynasty and Rough Country titles run a single 2019-2026 range across 1500, 2500HD and 3500HD, and that cuts across what the others say. Maybe a 2019 HD is covered there and maybe the title is loose. We cannot tell from the words, so on a 2019 HD, ask first.

Not sure about a 1500 labeled 2019? That is a different trap, covered on 2019 Silverado LD running boards. The 2027 Silverado 1500 is also a separate question: titles reaching 2027 name the HD, a different truck, and 2027 Silverado running boards has the details.

Silverado or Sierra: read the title

The Tyger titles name both Chevy Silverado and GMC Sierra. COMNOVA's 2020-up title says "Silverado/Sierra 2500HD 3500HD". But the Auto Dynasty Regular Cab title says only Silverado, so a Sierra owner should ask. Go by the words in the listing and not by how alike the trucks look.

What the two Tyger sheets say

2020-up, TG-SS2C35068. Eight brackets, attached to threaded holes in the body, with no drilling step. The sheet says assistance is recommended. It gives no install time and no load rating, so we print neither.

2007-2019, TG-SS2C35018. Same idea, with one thing diesel owners need to know. The sheet opens with "ON MODELS WITH DEF TANK" and warns the job may require cutting. On the passenger side, the DEF tank sits close to the body and room for the front brackets is very limited.

• Up to 2016 models: it may be easier to drop the tank for access. A full tank is heavy, so the sheet recommends doing the job when it is low on fluid, with help.
• 2017 and later: on the 2500 and 3500, the sheet says to remove only the plastic cover and not to lower or remove the tank. A figure shows that cover cut as an example.

Read that sheet before you start, and do not guess at the tank. The older truck in general is on 2007-2018 Silverado.

The COMNOVA 6-inch^* and the aluminum boards^* give you a wider flat step than the Rider, both on listing data only. The aluminum title stops at 2026, and it adds "Excl 2019 Ld/Lt" for the 1500. For older extended trucks, the COMNOVA Double Cab^* title says Double Cab and Extended Cab in one line. ARIES files the Silverado and Sierra Double under extended and uses the word Extended for older ones, so match it to your own doors. The two-door crowd gets the DNA Motoring^* for 2007-2019 and the Auto Dynasty^* for 2019-2026. Check your exact year and cab on the listing before you buy.

If you are shopping these trucks because you want something built stout, heavy-duty running boards explains why that phrase on a step is not a rating. Westin states "300 lbs. of weight capacity per side" for its Pro-e. The other parts here state no load in what we read, so we print none.

Powered steps on the HD

The Rough Country title^* names 1500/2500HD/3500HD for 2019-2026 Crew Cab, and it names no part number. The sheet we read for that family is headed "CHEVY 2019-23 1500/2500", which is narrower on both years and models, and it has you drill a 7/16-inch hole through a floor grommet. Ask which sheet ships with your truck.

AMP's guide for 76255-01A has one line reading "Silverado 1500/ GMC Sierra 2500/3500" for 2024-2026. It mixes models in a way that looks like an error, so we do not use it. Ask RealTruck about any HD truck. Power running boards covers the wider picture.
