onlyfire Universal Rotisserie Kit for 2 to 4 Burner Gas Grills, 32-42 Square Spit Rod Review (2026)

What comes in the kit

This onlyfire kit ships as a three-section spit rod, made up of a 16 inch piece, a second 16 inch piece and an 8.46 inch piece, that combine with a rod connector to span roughly 32 to 42 inches depending on how the cooking box is measured. Also included are two heavy duty four-prong meat forks, a counter balance to offset unevenly shaped roasts, a spit handle for manual checks, mounting brackets, screws and an electric motor. Because the rod assembles from separate sections rather than shipping as one fixed length, buyers get some flexibility to match a specific grill's cooking box rather than being locked into a single size.

Motor and turning capacity

The kit runs on a small electric motor built to keep the spit turning at a steady, continuous rate so food cooks evenly on all sides instead of sitting still on one edge. onlyfire rates the setup for up to 20 pounds of food, which covers whole chickens, pork loins, rib roasts and similar cuts, but the brand does not recommend it for whole lambs or pigs, since that exceeds what the motor and rod are built to carry. The square profile of the 5/16 inch rod is meant to keep the meat forks from twisting once they are tightened down.

Which grills it fits

onlyfire markets this as a universal kit for most 2 to 4 burner gas grills, but it specifically excludes Weber gas grills and the Char-Griller 5050 Duo, so those owners need a different kit. Because the rod length is adjustable across a range rather than fixed, the brand recommends measuring the grill's cooking box before ordering to confirm the parts will combine to the right span. On some grill models the universal brackets may need new holes drilled to mount securely, since the kit is not built around one specific grill's existing hardware. Checking the cooking box width against the 32 to 42 inch range before buying is the best way to avoid returning a kit that ends up too short or too long once assembled.

Square rod versus round rod

A square spit rod, as used here, is a common upgrade over round rods because the flat sides bite into the meat fork's mounting screws and resist spinning independently of the rod during rotation. That matters most with heavier or unevenly balanced items like a stuffed roast, where a round rod can let the food slip and cook unevenly even while the rod itself keeps turning. This is one of the more consistent advantages cited for square and hexagon rod designs generally, compared to older round rod rotisserie kits sold as bare replacement parts.

Who this kit suits

This kit is a solid match for owners of a typical 2 to 4 burner gas grill who want a full rotisserie setup, motor included, in one purchase rather than sourcing a rod, forks and motor separately. It is priced as a complete accessory kit rather than a premium standalone motor system, which fits buyers who rotisserie cook occasionally rather than several times a week. Owners of the widest multi-burner grills, built-in island grills, or Weber-branded grills will need to look at a longer rod or a brand-specific kit instead, since this one is sized and shaped for mid-size standard grills.
