Andersen Hitches Trailer Jack Blocks 2-Pack — 8" Magnetic Leveling Stabilizer Blocks, 12" Base for RVs

Andersen Hitches Trailer Jack Blocks 2-Pack are magnetic, 8-inch-high leveling/stabilizer blocks that secure your RV or trailer jacks on uneven or soft ground for faster, safer campsite setup.

These two heavy-duty jack blocks combine a tall stacking profile with wide-footed stability and integrated magnets to keep your trailer's round jack pads locked in place. Built in the USA and backed by a lifetime warranty, the pair is sized to support heavy loads while reducing jack slippage and sinking on gravel, dirt, grass, or soft campsites.

How do these jack blocks make leveling and stabilizing easier?

The magnets snap the block to your trailer’s round jack pad so the block stays aligned while you crank down. Their 8" height reduces the number of stacks needed on uneven ground, and the broad 12" base spreads weight to cut tipping and sinkage.

• Top-mounted magnets hold jack pads in place during setup
• 8-inch tall profile for greater lift per block
• 12-inch base increases footprint for stability on soft surfaces
• Two blocks let you support two corners or a pair of jacks simultaneously

What loads and stacking limits do these blocks support?

Each block is rated for 8,000 lbs when single-stacked and 1,500 lbs when double-stacked, suitable for most common stabilizer and leveling jack applications. Use single stacking for maximum capacity and follow the double-stack limit to avoid overloading the blocks.

• Single-stack capacity: 8,000 lbs per block
• Double-stack capacity: 1,500 lbs per block
• Designed for stabilizer and leveling jacks, not as a primary vehicle support on lifts
• Pair included for complete corner support

Will these blocks work on different ground types and jack pads?

The wide base and tall profile are built to perform on grass, gravel, packed dirt, and softer campsite soils. The integrated magnets are designed for round trailer jack pads—locking the block to the pad prevents wandering or twisting while you crank the jack.

• Works well on soft or uneven surfaces to reduce sinking
• Magnet engagement suits round jack pads commonly found on trailers
• Wide 12" footprint reduces tipping risk on slopes or loose ground
• Avoid use as a replacement for certified vehicle lift stands

What warranty and manufacturing assurances does Andersen Hitches provide?

These jack blocks are made in the USA and come with Andersen Hitches' lifetime warranty, giving long-term coverage against manufacturing defects. The warranty and domestic production mean you have support and replacement options if issues arise.

• Made in the United States for consistent quality control
• Lifetime warranty from Andersen Hitches for peace of mind
• Two-pack configuration backed by the same warranty terms
• Customer support available through Andersen Hitches for claims

Who is this for: These jack blocks are ideal for RV owners, trailer users, and campers who want a faster, more secure way to level and stabilize their rigs on uneven or soft ground. If you need reliable corner support without frequent readjusting—especially when using round jack pads—this two-pack gives a convenient, durable solution with a wide base, strong single-stack capacity, and the confidence of a lifetime warranty.
