KIKIRV Trailer Jack Blocks — 6" Height 4-Pack, 40,000 lb Stackable RV Leveling Pads

KIKIRV 6" Trailer Jack Block 4-Pack are stackable, high-strength leveling pads that support up to 40,000 lbs and keep your RV or trailer stable on uneven ground.

These polymer jack blocks provide a compact, portable solution for stabilizing tongue jacks, wheel jacks, scissor stabilizers and 5th wheel hydraulic jacks. Built from high-performance, weather-resistant material, each pad resists UV, oil, water, heat and stains so they stay effective outdoors season after season. The set of four lets you stack to the height you need while a locking-stacking design prevents shifting under load.

How do these blocks increase stability for my RV or trailer?

The KIKIRV jack blocks enlarge the contact area beneath jacks, reducing sink-in and wobble on soft or uneven ground. Their non-slip top and interlocking stacking feature keep jacks centered and prevent lateral movement when parked or being loaded.

• Wide, textured top improves grip for jack feet and pads
• Locking stack design prevents dangerous shifting while stacked
• Each pad rated to support 40,000 lbs for dependable load-bearing
• Drainage holes avoid water pooling that can soften soil beneath

Can I use them with different types of jacks and stabilizers?

Yes — these blocks are made for universal use with tongue and wheel jacks, scissor stabilizers and most 5th wheel hydraulic jacks. The geometry and size accommodate a variety of foot plates and jack styles without special adapters.

• Works with standard trailer tongue jacks and wheel jacks
• Compatible with scissor-style stabilizers and 5th wheel jacks
• Stackable design adapts to uneven surfaces and variable heights
• Robust polymer resists deformation under repeated heavy loads

How do I adjust height and transport the blocks?

Height is adjusted by stacking one or more pads — each provides 6 inches of lift — and a locking mechanism keeps stacked units secure. The set includes a rope and storage bag for tidy transport, and built-in drainage holes reduce weight from water and extend service life.

• Each block gives 6" height; stack to reach required clearance
• Locking stacking ribs align and secure multiple pads
• Comes with carrying rope and storage bag for convenience
• Side drainage holes prevent water retention and freeze damage

What durability and weather protections do these pads offer?

Manufactured from a high-performance polymer blend, KIKIRV blocks resist UV fading, oil, heat, stains and water, so they remain functional after long outdoor exposure. Each pad is quality-inspected before shipment to ensure uniform strength and reliability.

• UV-resistant polymer prevents sun degradation
• Oil, heat and stain resistance for messy road conditions
• Solid load-bearing design with quality inspection for consistency
• Low-maintenance—wipe clean and store in provided bag
