What Material is Best for Body Lift Blocks?

When it comes to upgrading your off-road vehicle, one of the most critical decisions you'll make is choosing the right material for your body lift blocks. Historically, aluminum has been a popular choice for body lift blocks due to its lightweight nature and resistance to corrosion. However, the tides are changing as more off-road enthusiasts are discovering the superior benefits of cast iron body lift blocks. In this blog, we’ll go over why aluminum is becoming a thing of the past and how cast iron is revolutionizing the off-roading world.


The Downfall of Aluminum Body Lift Blocks


Aluminum body lift blocks were once the go-to material for many off-roaders. The appeal of aluminum lay in its lightweight properties and its ability to resist rust and corrosion. However, while these benefits are significant, they come with substantial drawbacks that are hard to overlook.


Strength and Durability

Aluminum, despite being strong, cannot match the sheer strength and durability that cast iron offers. Over time, aluminum lift blocks can suffer from fatigue and may not withstand the constant stress and strain of intense off-roading. This can lead to a higher likelihood of cracks or failures, which can be dangerous and costly to repair.

Deformation

Aluminum is more prone to bending and deforming under heavy loads. For off-road vehicles, which frequently encounter rough terrains and heavy impacts, this is a significant disadvantage. The flexibility of aluminum means it can warp, leading to misalignment and potential damage to other vehicle components.

The Rise of Cast Iron Body Lift Blocks


Cast Iron is the game-changer for body lift blocks. Cast iron has been recognized for its robustness and longevity, making it the superior choice for those serious about off-roading. Here’s why cast iron body lift blocks are outshining their aluminum counterparts:


Exceptional Strength

Cast iron is renowned for its high strength and ability to withstand immense pressure and stress. This makes it ideal for body lift blocks, which need to support the vehicle's weight and absorb the shocks from rough terrains. Unlike aluminum, cast iron is less likely to crack or break, providing a more reliable and safer lift solution.

Durability & Longevity

Off-road vehicles are subjected to harsh conditions that require components to be exceptionally durable. Cast iron body lift blocks excel in this area due to their resistance to wear and tear. They can handle the repeated impacts and stresses of off-roading without deforming or failing, ensuring your lift remains stable and effective for a longer period.

Heat Resistance

Cast iron also has superior heat resistance compared to aluminum. This property is crucial in off-roading scenarios where the vehicle may be exposed to high temperatures. Cast iron blocks maintain their structural integrity under heat, further enhancing their durability and reliability.

Off-Roaders Making the Switch


With the growing recognition of these benefits, off-road enthusiasts are increasingly switching from aluminum to cast iron body lift blocks. The strength, durability, and reliability of cast iron make it the preferred choice for those who demand the best performance from their vehicles. Whether you're tackling rocky trails, muddy paths, or sandy dunes, cast iron body lift blocks provide the confidence and stability you need.
