Best Swing Out Door Bar Kits for Roll Cage Access
The best swing out door bar kit depends on your roll-cage tube diameter, wall thickness, and race-series requirements. Speedway Motors’ 1.625-inch kit is best for buyers seeking a billet-steel, quick-release design, while its 1.75-inch version is better for a larger listed tube configuration. Competition Engineering’s C3183 is a choice to consider for specified NHRA applications. Compare the fitment details below before choosing; the tube size and inside-diameter requirements must match your cage.
| Kit | Best For | Key Fitment Detail |
|---|---|---|
| Speedway Motors 1.625-inch | Quick access and listed 1.625-inch tubing | 1.625-inch OD, .120-inch wall |
| Speedway Motors 1.75-inch | Quick access and listed 1.75-inch tubing | 1.750-inch OD, .095-inch wall |
| Competition Engineering C3183 | Specified NHRA applications | 1.625-inch steel tubing |
| UTVDistribution 1-3/4-inch | Heavy-duty steel hinge construction | 1.490–1.540-inch tube ID |
| JEGS 64452 | 1-3/4-inch tubing with .134-inch wall | 1.75-inch diameter |
Speedway Motors 1.625-Inch Swing Out Kit
This Speedway Motors kit is best for roll-cage owners who want a removable bar and easy entry or exit through a quick-release pin. It is made from CNC-machined billet 1018 alloy steel. The listed complete kit is for one door and includes two female plugs, two male plugs, a release pin, and hardware.
The product is listed for 1.625-inch tubing, and the provided fitment details specify 1.625-inch outside diameter with .120-inch wall thickness. It was selected for its clearly described construction and included parts. Avoid choosing it based on outside diameter alone: confirm that the cage tubing matches the required dimensions before ordering.
Speedway Motors 1.75-Inch Removable Kit
Choose this kit if your cage uses one of the two tube configurations listed by Speedway Motors: 1.625-inch outside diameter with .120-inch wall or 1.750-inch outside diameter with .095-inch wall. Its swing-out mechanism uses a quick-release pin to allow access, and its fittings are CNC machined from solid 1018 alloy steel.
This option is best for buyers whose tubing matches the stated fitment and who want a machined-steel design. The listing does not establish fitment for every tube-wall combination, so check both the outside diameter and wall thickness. Do not assume that all 1.75-inch tubes are interchangeable.
Competition Engineering C3183 Kit
The Competition Engineering C3183 is best for buyers considering a swing-out bar for a qualifying NHRA application. The listed information says it meets an NHRA rule for OEM full-body cars running 7.50 E.T. and slower, and is designed for 1.625-inch steel tubing. Its stated kit components include a door bar, release pin, and hinge bracket.
It was selected because the product description identifies both a tubing size and a specific rule context. That does not mean it is suitable for every vehicle or event. Confirm current class rules and your vehicle’s requirements with the relevant sanctioning body before relying on the listing’s rule claim.
UTVDistribution 1-3/4-Inch Heavy-Duty Kit
This hinged quick-release kit is best for buyers whose 1-3/4-inch outside-diameter tubing has an inside diameter between 1.490 and 1.540 inches. It is machined from 1018 alloy steel. The listed hardware includes a stainless-steel shoulder bolt, washer, nyloc nut, and quick-release pin.
The inside-diameter specification makes this option useful when a buyer needs more than an outside-diameter match. It was selected for its explicit fitment range and included hardware. Avoid this kit if the tube’s inside diameter falls outside the stated range; the listing does not provide a broader fitment claim.
JEGS 64452 1-3/4-Inch Kit
The JEGS 64452 is best for buyers looking for a kit listed for 1-3/4-inch-diameter tubing with a .134-inch mild-steel wall. Its stated finish is natural. This makes it a straightforward candidate when those specifications match the existing cage.
It was selected as a size-specific alternative to kits with different wall or inside-diameter requirements. The supplied product details do not describe included hardware or a quick-release mechanism, so verify those details in the listing before ordering if they matter for your installation.
Buying Guide: How To Choose A Swing Out Door Bar Kit
Which tube measurements should you check?
Measure the tube’s outside diameter and confirm its wall thickness or inside diameter against the kit specifications. A nominal 1.75-inch outside diameter does not by itself prove fitment: the UTVDistribution kit, for example, also specifies a 1.490–1.540-inch inside diameter. Compare the exact measurements rather than relying on a general size label.
Do you need a quick-release pin?
A quick-release pin lets the bar swing out or be removed for access, according to the relevant product descriptions. Check whether the kit includes the pin and other necessary hardware. The listings do not all describe their contents in the same level of detail.
Do race rules affect your choice?
If the car will be used in organized competition, check the applicable rulebook and confirm the complete vehicle configuration meets its requirements. The C3183 listing describes a particular NHRA application; that statement should not be treated as universal approval for other classes or vehicles.
How should you compare construction?
Compare stated material and manufacturing details, such as 1018 alloy steel or mild steel, along with the hinge and release components. These details help distinguish products, but they do not replace confirmation of tube fitment or installation requirements.
