BAL X-Chock vs Deluxe Chock vs Single-Axle Tire Leveler
A tire chock and a tire leveler may sit beside the same trailer wheel, but they perform different jobs. BAL offers between-tire stabilizers for tandem axles, a separate locking chock for a single tire, and a tire leveler that raises one side of a light single-axle trailer. Start with your axle arrangement and the task you need to accomplish before choosing a part.
Do you want to stabilize tires or level the trailer?
Tandem axle: 28005 or 28010Both fit between adjacent tires and reduce tire shifting after the trailer is parked. BAL's Deluxe 28005 is a mini-scissor design requiring at least 2½ inches of tire clearance; the slimmer 28010 X-Chock retracts to 1⅜ inches. Both extend to 10 inches. These are stabilizing devices, not jacks that raise a tire.
Single axle: 28020 or 2805028020 adjusts around an individual tire to resist rolling or shifting. BAL 28050 is a different device: its tire-support pads move vertically, helping level a lightweight single-axle trailer from side to side. BAL identifies 28050 for trailers with 2,000–3,000 lb GVWR and 13-inch, 14-inch or most 15-inch wheels.
BAL part-number and application comparison
| Manufacturer MPN | Function | Fit requirement | Quantity |
|---|---|---|---|
| 28005 | Tandem-axle tire stabilizer | 2½–10 in tire gap | Single |
| 28010 | Tandem-axle tire stabilizer | 1⅜–10 in tire gap | Single |
| 28020 | Single-axle tire restraint | Wraps around one tire | Single |
| 28050 | Single-axle side-to-side leveling | 13, 14 and most 15 in wheels | Single |
The 28005 and 28010 use different mechanisms even though both are designed for tandem tires. The 28020 wraps around a single tire rather than reaching between two, while the 28050 changes the tire's height for leveling. Product fit must be established using the complete BAL number and actual wheel and trailer dimensions.
Wheel safety matters. Do not rely on an X-Chock as the trailer's parking brake or only roll restraint. Use suitable under-tire wedges and follow the trailer manufacturer's parking procedure before installing stabilizing equipment. BAL instructs users to level the trailer before installing between-tire chocks and to remove them before hitching or operating jacks in a way that strains the chock.
Measure and check before ordering
- Count the axles. A tandem-tire stabilizer requires adjacent tires on the same side of the trailer. A single-axle trailer needs a different device.
- Measure between the tandem tires. For 28005, BAL specifies 2½–10 inches of clear space; 28010 is intended for 1⅜–10 inches. If your gap exceeds 10 inches, check a suitable extended-range X-Chock rather than forcing either model.
- For single-axle leveling, check GVWR and wheel size. The 28050 is listed for lightweight single-axle trailers in the 2,000–3,000 lb GVWR range with 13-, 14- and most 15-inch wheels. Verify the actual tire clearance and the manufacturer's installation instructions.
- Check package contents. Each of these four listings is for one device, not a pair. BAL lists a hand-operated ratchet wrench for the 28005, 28010 and 28050. Optional padlocks or other accessories should not be assumed included.
- Follow the setup sequence. Park on suitable ground, secure the wheels with conventional chocks, perform the required leveling, and then apply any additional stabilizer as directed. Do not use a high-torque impact tool to force the screw mechanism.
Which model is closest to your situation?
For a tandem trailer with a tight tire gap, compare the 28010 X-Chock. For a tandem installation with 2½ inches or more between tires, 28005 Deluxe is another design to evaluate. A lightweight single-axle trailer needing height adjustment calls for the purpose-built 28050 leveler; if the goal is to secure an individual tire against movement, compare the 28020 chock. None of these choices eliminates the need to follow the trailer's proper parking and support instructions.
