What Are Slip-on Rocker Panels?
Slip-on rocker panels, also known as rocker panel covers, are essentially pre-fabricated metal panels designed to be installed over your existing, damaged rocker panels. They’re typically made of steel, although some are available in aluminum or other materials. The idea is simple: you clean up the existing rust, slip the new panel over the old one, and secure it in place. This can involve welding, riveting, or using adhesives, depending on the panel and your preferred installation method.
These panels come in various sizes and shapes, designed to fit a wide range of vehicles. You can often find them pre-cut for specific makes and models, making the installation process more straightforward. They’re a popular choice for DIY enthusiasts and those looking for a more budget-friendly alternative to complete rocker panel replacement or extensive bodywork.
Materials Used in Slip-on Rocker Panels
The material of a slip-on rocker panel significantly impacts its durability, rust resistance, and overall performance. Here’s a breakdown of the common materials:
- Steel: Steel is the most common material due to its affordability, strength, and ease of welding. However, it’s susceptible to rust, so proper surface preparation and protective coatings are crucial. Different grades of steel offer varying levels of corrosion resistance.
- Aluminum: Aluminum rocker panels are lighter than steel and offer excellent corrosion resistance. They don’t rust. However, they can be more expensive and may require specialized welding techniques.
- Stainless Steel: Stainless steel panels are highly resistant to rust and offer excellent durability. But they’re typically the most expensive option and can be challenging to work with due to their hardness.
- Galvanized Steel: Galvanized steel is steel that has been coated with a layer of zinc. This coating provides added protection against rust. Galvanized panels are a good compromise between cost and corrosion resistance.
Types of Slip-on Rocker Panels
There are a few different styles of slip-on rocker panels available, each with its own advantages and disadvantages:
- Full-Length Panels: These panels cover the entire length of the rocker panel, from wheel well to wheel well. They offer the most comprehensive protection and are often preferred for vehicles with extensive rust damage.
- Partial Panels: Partial panels cover only a portion of the rocker panel, typically the area most prone to rust. They’re a good option if the damage is localized and you want to save money.
- Replacement Panels: Replacement panels are designed to replace the entire rocker panel. They are often spot welded into place, and offer a more permanent repair option.
