The 1973-1987 Chevrolet Square Body Chevy trucks are an iconic part of American automotive history. These classic pickups are loved for their sturdy build, timeless design, and raw power. However, one of the most common modifications made to these trucks is lowering the ride height. Lowering a Square Body Chevy not only improves the truck’s aesthetics but also enhances its handling and performance. By reducing the distance between the truck and the road, it gains a sleeker, sportier appearance and better road stability.
In this guide, we’ll walk you through the right way to lower your Square Body Chevy, covering both front and rear suspension modifications, rust treatments, and steering column options to achieve a smooth, professional look and feel for your truck.
Key Methods for Lowering Your Square Body Chevy
There are many ways to lower a Square Body Chevy, but achieving the best results requires the right approach. While you can use cutting-edge tools and components to lower the truck’s ride height, it’s crucial to choose the most effective methods that not only improve the truck’s performance but also maintain its safety and integrity. We’ll focus on the two most popular and effective methods: the axle flip for the rear and the dropped spindle suspension for the front.
Lowering the truck by up to 6 inches can significantly change its stance and handling, so let’s dive into the specific details of these methods.
Axle Flip: Lowering the Rear End
The axle flip is one of the simplest yet most effective methods for lowering the rear end of your Square Body Chevy. By flipping the axle over the leaf springs, you can lower the truck’s rear suspension by up to 5 inches. This technique is commonly used in the sport truck scene and provides a significant reduction in ride height without sacrificing the truck’s load-carrying ability or stability.
To perform an axle flip, follow these steps:
- Lift the Truck: Begin by safely lifting the rear of the truck using a jack and securing it with jack stands. Make sure the vehicle is stable before you begin working.
- Remove the Rear Suspension: Disconnect the rear leaf springs, shocks, and any other suspension components that may interfere with the axle flip. This will give you clear access to the axle.
- Flip the Axle: Once the suspension components are removed, flip the axle upside down, positioning it over the leaf springs. This method will lower the truck by several inches.
- Reinstall the Suspension: Carefully reinstall the suspension components, ensuring everything is correctly aligned and torqued to specifications. Double-check that the axle is properly secured in its new position.
Once the axle flip is complete, you should notice a significant drop in the rear end of your Square Body Chevy, enhancing its sporty look and improved handling. Keep in mind that while this method lowers the truck, it doesn’t compromise the truck’s payload capacity.
Dropped Spindle Suspension: Lowering the Front End
While the rear axle flip is a straightforward method for lowering the rear, the front suspension requires a more specialized approach. One of the most effective ways to lower the front of a Square Body Chevy is by installing a dropped spindle suspension. This method lowers the truck without compromising ride quality or geometry, making it a popular choice for enthusiasts who want to achieve a balanced, smooth ride.
To install a dropped spindle suspension, you’ll need to follow these steps:
- Lift the Front of the Truck: As with the rear suspension, start by lifting the front of the truck using a jack and securing it with jack stands.
- Remove the Front Suspension Components: Disconnect the shocks, sway bar, and other suspension parts to gain access to the front spindle assembly.
- Install the Dropped Spindles: Replace the existing spindles with dropped spindles designed specifically for your Square Body Chevy. Dropped spindles provide a lower ride height by changing the spindle’s angle without altering the suspension geometry.
- Reassemble the Suspension: After installing the dropped spindles, reassemble the front suspension components, making sure everything is correctly torqued and aligned.
Once completed, your Square Body Chevy will have a significantly lower front end, giving it a well-rounded stance. This method is ideal for maintaining proper suspension geometry and handling while achieving the desired lowered look.
Treating Rust with POR-15 Products
Before you lower your truck, it’s important to treat any rust that may be present. Rust can weaken the structure of your truck and reduce the longevity of its components. Using high-quality rust treatment products like POR-15 can protect your truck from further rust damage and help preserve the suspension system.
POR-15 is a rust-preventative paint that is specifically designed for automotive use. It provides a durable, long-lasting finish that prevents rust from forming and keeps your truck looking pristine. When lowering your Square Body Chevy, make sure to clean and treat any rusted areas before starting the suspension work.
To apply POR-15, follow these steps:
- Prepare the Surface: Sand down any rusted areas and clean the surface to remove dirt and debris.
- Apply POR-15: Use a brush or spray gun to apply POR-15 to the affected areas. Apply multiple coats if necessary, following the manufacturer’s instructions.
- Allow to Cure: Allow the POR-15 to cure for the recommended time, ensuring maximum protection against rust.
This treatment will help prevent rust from affecting your newly lowered truck, allowing you to maintain its appearance and functionality for years to come.
Steering Column Options for C10 Pickups
If you’re working on a first-generation C10 two-wheel drive pickup, you might also be considering options for your steering column. When lowering your truck, the steering column might need to be adjusted to accommodate the new ride height. There are several steering column options available, including:
- OEM Steering Columns: Retain the original steering column, but modify it to fit the lowered position.
- Custom Steering Columns: Upgrade to a custom steering column for a more modern look and feel, which can offer more adjustability and features.
- Aftermarket Columns: Several aftermarket companies offer replacement steering columns designed specifically for lowered trucks.
Choosing the right steering column will depend on your personal preferences and the level of modification you’re comfortable with. Just make sure to select a column that complements your lowered setup for optimal performance.
Conclusion
Lowering your Square Body Chevy is a great way to enhance its appearance and performance. Whether you’re opting for the rear axle flip, the dropped spindle suspension, or both, each method will bring a unique transformation to your truck. Don’t forget to treat any rust with POR-15 products to ensure your vehicle remains in top condition, and consider upgrading your steering column to match the new ride height. With these tips, you’ll be able to achieve a lowered, sleek, and stylish Square Body Chevy that stands out on the road.
