Oem And Aftermarket Rear Bumper Options For The S13 Chassis

So, you're wrestling with a less-than-perfect rear bumper on your S13. Whether it's battle scars from spirited driving, the slow creep of rust, or simply a desire for a fresh look, you've come to the right place. This guide will walk you through the various OEM and aftermarket rear bumper options available for your S13 chassis (both coupe and hatch), helping you choose the best fit for your needs, budget, and style.

Understanding the S13 Rear Bumper Landscape

Before diving into specific options, let's establish some groundwork. The S13, produced from 1989-1994 (depending on the market), came in two primary body styles impacting bumper compatibility: the coupe (also known as the 240SX) and the hatchback (often referred to as the fastback). While some parts are interchangeable, rear bumpers are not. Ensure you're searching for a bumper designed specifically for your body style.

Also, be aware of the different trim levels. While the overall bumper shape remained consistent, some subtle variations existed in valances and lower lips, especially in later model years. Knowing your car's original trim can help maintain its original aesthetic, or provide inspiration for modifications.

OEM Replacement: Restoring to Original Glory

Finding an OEM Bumper

Locating a genuine Nissan OEM rear bumper for an S13 can be challenging, but not impossible. Here's where to look:

Online Marketplaces: Websites like eBay, Craigslist, and specialized forums dedicated to the 240SX often have listings for used OEM bumpers. Be prepared to sift through listings and carefully inspect photos for condition.
Local Junkyards: If you have the time and patience, visiting local junkyards can be a goldmine. You might stumble upon an S13 with a salvageable rear bumper. Be ready to remove the bumper yourself – bring your tools!
Nissan Dealership (Limited Availability): While unlikely, it's worth checking with your local Nissan dealership. They might have access to discontinued parts or be able to source one through their network. Don't hold your breath, but it's worth a shot.

Pros and Cons of OEM

Pros:

Perfect Fitment: Designed specifically for the S13 chassis, ensuring seamless integration and proper mounting.

Original Aesthetics: Maintains the factory look and feel of your S13.

Durability: OEM bumpers are generally made from high-quality materials, offering decent impact resistance.

Cons:

Scarcity: Finding a good condition OEM bumper can be time-consuming and challenging.

Cost: Depending on the condition and availability, OEM bumpers can be relatively expensive.

Potential for Damage: Used bumpers may have existing scratches, dents, or rust.

What to Look For When Buying Used OEM

Rust: Pay close attention to areas prone to rust, such as the mounting points and lower sections.
Dents and Scratches: Assess the severity of any damage and factor in the cost of repair.
Cracks: Thoroughly inspect the bumper for cracks, especially around the mounting points and corners.
Completeness: Ensure the bumper includes all necessary mounting hardware, brackets, and reflectors.

Approximate Cost of OEM Replacement

A used OEM rear bumper in decent condition can range from $200 to $500+, depending on its condition and rarity. Factor in additional costs for shipping, paint (if needed), and installation.

Aftermarket Rear Bumper Options: Style and Performance

The aftermarket offers a vast array of rear bumper options for the S13, catering to various styles, budgets, and performance goals. These can range from subtle enhancements to aggressive, race-inspired designs.

Types of Aftermarket Bumpers

Direct Replacements: These bumpers are designed to mimic the OEM fit and mounting points, making installation relatively straightforward. They often feature subtle styling enhancements or are made from different materials like fiberglass or polyurethane.
Aero Kits/Body Kits: These kits include a complete set of bumpers, side skirts, and other aerodynamic components designed to dramatically alter the car's appearance. Installation can be more complex and may require modifications.
Drift/Aggressive Styling: These bumpers typically feature wider openings, integrated diffusers, and more pronounced designs aimed at improving airflow and adding a more aggressive aesthetic.

Material Choices: Fiberglass vs. Polyurethane

Two common materials dominate the aftermarket bumper landscape:

Fiberglass (FRP):
- Pros: Lightweight, relatively inexpensive, can be molded into complex shapes.
- Cons: Brittle, prone to cracking upon impact, requires more extensive preparation before painting. Fitment can be inconsistent.
Polyurethane (PU):
- Pros: More flexible and impact-resistant than fiberglass, less prone to cracking, easier to install (generally better fitment).
- Cons: Heavier than fiberglass, more expensive, may require some trimming or adjustment for perfect fitment.

For a daily driver, a polyurethane bumper is generally recommended due to its superior durability. If weight savings is a primary concern and you're willing to accept the increased risk of damage, fiberglass may be a suitable option.

Popular Aftermarket Brands

Several reputable brands offer high-quality aftermarket bumpers for the S13. Some popular choices include:

VIS Racing: Offers a wide range of fiberglass and carbon fiber body kits and bumpers.
Duraflex: Specializes in fiberglass-reinforced plastics, offering a balance of affordability and durability.
Origin Lab: Known for their aggressive drift-inspired styling and high-quality fiberglass construction.
Shine Auto Project: Offers high-quality replica and original designs, often in fiberglass or polyurethane.

Things to Consider Before Buying Aftermarket

Fitment: Research the brand and specific bumper model to ensure good fitment. Read reviews and look for photos of the bumper installed on other S13s.
Material: Choose a material that suits your needs and driving style.
Quality: Opt for reputable brands known for their quality and craftsmanship.
Installation: Consider the complexity of the installation and whether you have the necessary skills and tools. Some bumpers may require professional installation.
Paint: Factor in the cost of professional painting, as most aftermarket bumpers come unpainted.

Approximate Cost of Aftermarket Replacement

Aftermarket rear bumpers can range from $200 to $1000+, depending on the material, brand, and complexity of the design. Polyurethane bumpers are typically more expensive than fiberglass ones. Add to that the cost of painting ($200-$500+) and installation ($100-$300+), unless you're tackling it yourself.

Installation Tips and Tools Needed

Whether you're installing an OEM or aftermarket bumper, the process is generally similar. Here's a basic overview:

Preparation: Disconnect the battery. Gather your tools: a socket set, wrench set, screwdriver set, pliers, and potentially a drill (for minor adjustments on some aftermarket bumpers). Consider having a friend help you, especially when aligning the bumper.
Removal of the Old Bumper: Locate and remove all mounting bolts and clips securing the old bumper. These are typically located in the wheel wells, under the trunk lid, and along the rear panel.
Test Fitment: Before painting, carefully test fit the new bumper to ensure proper alignment and clearance. Make any necessary adjustments. This is crucial for aftermarket bumpers.
Painting (if necessary): If the bumper requires painting, take it to a reputable body shop for a professional finish.
Installation: Reinstall the bumper, carefully aligning it with the mounting points. Secure it with the bolts and clips.
Final Check: Double-check all mounting points and ensure the bumper is securely attached. Reconnect the battery.

Important Note: Always consult the manufacturer's instructions for specific installation guidelines. Some aftermarket bumpers may require modifications to the vehicle or bumper itself.
