Available in 4-Pack, 8-Pack, and 10-Pack Options
Achieving a level, stable RV is one of the first—and most important—steps when setting up at any campsite. A properly leveled RV protects appliances, ensures comfortable sleeping, and helps slides, doors, and plumbing systems operate correctly.
Ultra-Fab Leveling Blocks provide a simple, reliable solution that gives RV owners the confidence they need when parking on uneven ground. With heavy-duty construction, interlocking design, and a lifetime warranty, these leveling blocks are designed for long-term durability and ease of use.
Available Pack Sizes & Part Numbers
To fit all RV types and campsite situations, Ultra-Fab offers three leveling block options:
- Leveling Blocks – 4 Pack — P/N 48-979050
- Leveling Blocks – 8 Pack — P/N 48-979052
- Leveling Blocks – 10 Pack — P/N 48-979051
Each set comes with a convenient storage bag for easy transport and organization.
Purpose-Built for RV Stability
Ultra-Fab Leveling Blocks are engineered to help RV owners quickly level their rig—while keeping everything stable and supported. Once the blocks are properly set, they won’t shift or collapse, even under heavy loads.
Whether you’re parked on gravel, dirt, grass, or uneven pavement, these blocks provide a dependable foundation for your RV wheels, jacks, and stabilizers.
Key Features & Benefits
✔ Level Any RV With Ease
Designed to make leveling simple. Just stack the blocks to your desired height, position your RV, and drive on. Once locked into place, the blocks maintain their stability without shifting.
✔ Ideal for Wheels, Jacks, and Stabilizers
While perfect for leveling, these blocks also work exceptionally well under:
- Tongue jacks
- Scissor jacks
- Stabilizer pads
- Landing gear feet
- Fifth-wheel front jacks
They’re a versatile tool that every RV owner should keep on hand.
✔ Interlocking, Stackable Design
Each block interlocks to form a secure, stable pyramid for achieving the correct height.
Each block adds 1″ of lift, making adjustments easy and precise.
✔ Heavy-Duty & Built to Last
Made from durable, high-strength plastic with an impressive 30,000 lb weight capacity.
Designed to handle large motorhomes, fifth wheels, travel trailers, and more.
✔ Compact Dimensions
Blocks measure 8.3125″ x 8.3125″, making them easy to store while offering plenty of tire support.
✔ Comes With Carrying Bag
Every pack includes a sturdy storage bag—keeps blocks clean, organized, and easy to transport.
✔ Lifetime Warranty
Ultra-Fab stands behind their blocks with a true lifetime warranty—a rare level of confidence in the RV accessory market.
Why Ultra-Fab Leveling Blocks Stand Out
Not all leveling blocks are created equal. Ultra-Fab’s design is engineered to prevent the most common problems RV owners face with lower-quality blocks:
- Collapsing under heavy load
- Slipping on uneven ground
- Breaking under weight
- Poor locking or unstable stacking
With over 65 years in the RV aftermarket, Ultra-Fab continues to provide high-quality leveling and stabilizing products trusted by RV owners across the country.
