onlyfire Universal Rotisserie Kit for Gas Grills — 45–53in 1/2in Hex Spit Rod, Waterproof Motor & Counterbalance

onlyfire Universal Grill Rotisserie Kit is a complete rotisserie system with a waterproof electric motor, counterbalance, heavy-duty forks, and adjustable hexagon spit rods (45"–53" x 1/2") that fit most gas grills.

This rotisserie kit supplies everything you need to convert a compatible grill into a slow-roasting rotisserie: a stainless-steel motor, three spit rod sections you can join for longer roasts, a counterbalance to steady uneven loads, and a universal bracket set designed to match popular grill brands. It’s built to handle whole chickens, roasts, and turkeys and to reduce motor strain with an auto-reverse and balancing system.

How does the motor perform and protect against outdoor conditions?

The electric motor is stainless steel and features an IP-safe waterproof on/off switch plus an auto-reverse function for smoother turning. Its construction reduces exposure to grill heat and moisture while the 36" power cable gives flexible placement options.

• Waterproof on/off switch for outdoor use
• Auto-reverse to prevent jammed rotation
• Stainless motor housing resists heat and corrosion
• 36" power cable for flexible mounting positions

What parts are included and how do they assemble?

The kit ships with three steel spit rod sections, heavy-duty four-prong forks, a spit handle, rod bushing, counterbalance, and both universal and OEM-style brackets. Sections join to create either a 45" or 53" span, and the included bracket set is designed to adapt to many named grill models.

• Three spit rods: 10", 22.75", and 22.75" that connect for extended length
• Four heavy-duty forks for secure meat mounting
• Counterbalance piece to steady asymmetric loads
• Universal and OEM brackets to fit Broil King, Broil Mate, Sterling, GrillPro and similar grills

How does the counterbalance improve rotation and motor life?

The included counterbalance offsets uneven weight distribution on non-centered roasts, providing steadier spinning and reduced motor strain. That means more consistent cooking and longer motor longevity when turning heavy or lopsided items.

• Balances uncentered roasts like whole turkeys or bone-in roasts
• Produces smoother turning, reducing wobble
• Lowers wear on the motor and gearbox
• Easy to attach and adjust on the spit rod

Will this fit my grill and how do I choose the right rod length?

The spit rod’s hexagon shaft measures 1/2" and comes in configurations to cover cookbox widths up to 39" (45" rod) or 47" (53" rod) once mounted with brackets. Before ordering, measure your cookbox width or compare to your original rotisserie parts to ensure a proper fit.

• 1/2" hexagon spit rod compatible with common rotisserie brackets
• 45" rod fits cookboxes up to about 39" wide
• 53" rod fits cookboxes up to about 47" wide
• Contact customer service if unsure about measurements

Who is this for: Grillers who want a durable, ready-to-install rotisserie upgrade that works with many mainstream grill brands. It’s aimed at backyard cooks roasting whole birds or large cuts who need a motorized, balanced turning system and a robust set of spit rods and forks to secure heavy loads.
