What is the diameter of a Ford Ranger roll bar?
The Ford Ranger does not have a single standard roll-bar diameter. Diameter varies by model year, market, and whether the bar is factory-installed or an aftermarket option. In practice, most Ranger bed bars use tubing in the 1.5" to 2.0" outer diameter range (about 38–50 mm).
Why the diameter varies
Roll bars on the Ranger are not universally standardized across all markets or generations. Some regions rely on aftermarket kits, while others may offer optional accessories through official catalogs. The intended use of the bar (aesthetics, mounting support, or load-bearing function) and the tubing thickness influence the overall diameter. Always verify the exact specification from the product documentation or the seller.
Common diameter sizes you’ll encounter
Before you shop, it helps to know the typical outer diameters you’re likely to see in Ranger roll-bar offerings.
- 1.5 in (38 mm) outer diameter — lighter-duty sport bars and budget kits
- 1.75 in (44.5 mm) outer diameter — very common for mid-range bars
- 2.0 in (50.8 mm) outer diameter — common for heavy-duty and off-road kits
The outside diameter is the key measurement for compatibility with mounting brackets and other accessories; wall thickness and material (steel vs. aluminum) also affect strength.
In short, most Ranger roll bars you’ll encounter will be in the 1.5" to 2.0" range. Always confirm the exact diameter from the kit’s specifications before purchase.
Details by application
There are differences between bed-mounted sport bars and rarer cab/roll-bar configurations. The choice of diameter can affect compatibility with tonneau covers, bed liners, and other mounting hardware, so match the bar to your truck setup and planned use.
How to determine the diameter on your Ranger
If you already own a Ranger or are evaluating a specific kit, use these steps to confirm the exact diameter of the roll bar you’re dealing with.
- Look up the kit’s model number or Ford part number and read the official specifications from Ford's accessory catalog or the supplier’s listing.
- If the bar is accessible, measure the outside diameter with a caliper or ruler at a straight section of the tube.
- Compare your measurement to common sizes (1.5", 1.75", 2.0") to identify the closest match.
- When in doubt, contact the dealer or the kit manufacturer with your Ranger’s year, market, and the bar’s model number to confirm the exact diameter and compatibility.
Accurate measurement helps ensure compatibility with accessories, brackets, and load ratings.
Summary
The Ford Ranger does not have a universal roll-bar diameter; most aftermarket options fall in a 1.5" to 2.0" outer diameter range, with 1.75" and 2.0" being the most common. OEM availability and exact sizes vary by market and model year, so always verify the specification from product literature or the dealer. If you’re unsure, measure the bar directly or consult the manufacturer to ensure a proper fit and safe installation.
