Curved Leveling Blocks for Tandem Axle Trailers - 6in Lift for Tire

Our review of these curved leveling blocks finds them most useful for RV owners and tow operators who need a simple, non-jack way to lift a tandem axle wheel for tire changes or quick maintenance. The single biggest reason to consider them is the built-in 6in lift height and gear-mesh anti-slip interface that lets users raise a dual-wheel trailer enough to change a tire without wrestling with a hydraulic jack. They are presented as heavy duty and UV-resistant, aimed at practical roadside use rather than precision campsite leveling.

Key Features

• 6in lift height: Provides enough clearance to change a tire on a tandem axle trailer without using a jack, simplifying roadside repairs.
• Heavy duty capacity: Rated for trailers up to 35,000 lb with tire sizes up to 32in, offering support for many medium and large tow rigs.
• Premium polymer construction: Made from reinforced polymers with anti-aging and UV-resistant additives to slow weather-related degradation.
• Double anti-slip design: Leveler and chock use a precise gear mesh and thickened rubber non-slip pads to reduce slippage under load.
• Complete kit: Each 2-pack includes a matching chock and rubber mat to stabilize and protect the tire and contact surface during lifting.

Who It's For

These leveling blocks suit RV and trailer owners who tow tandem axle trailers and want a quick, tool-free way to lift one wheel for tire changes or short repairs. They are particularly helpful for operators of travel trailers and campers with tires up to 32in who need a compact, reusable option instead of hauling a heavy jack.

They are less suitable for users who need precision campsite leveling or for operators who frequently exceed the stated tire size or gross trailer weights, and anyone who expects indefinite life under extreme off-road abuse should consider them a maintenance item rather than a permanent solution.

Pros & Cons

Pros

• Strong lift capability that handled a 15k trailer in customer reports, showing real-world usefulness for many tow rigs.
• Solid build from UV-resistant polymers helps longevity when stored on a trailer or in a garage.
• Anti-slip gear mesh and thick rubber pads improve stability during a tire change.

Cons

• Some users reported cracking on repeated use, so durability may vary under heavy repetition or impact.
• Designed for lifting a wheel for service rather than precise leveling, so not a campsite leveling substitute.
