2014-2017 Chevrolet Caprice PPV Rear Spoiler: Fitment, Installation, and Holden Swaps

Vehicle-Specific Information: The Caprice PPV and Holden Connection

The 2014-2017 Chevrolet Caprice sold in North America was exclusively a Police Pursuit Vehicle (PPV) and was not available to the general public when new. This vehicle is a rebadged version of the Australian-built Holden Caprice (WN series) and is closely related to the Holden Commodore (VF series). This is critical information for sourcing parts, as many spoilers from Australian suppliers listed for the Holden VF Commodore or WN Caprice will fit the Chevrolet Caprice PPV.

Rear spoilers were not standard equipment on all Caprice PPV models. Many were 'slicks-top' vehicles without any spoiler. Therefore, adding one often requires a fresh installation rather than a simple replacement.

Symptoms of a Damaged Rear Spoiler

As a static body part, a spoiler's failure is purely physical. Common symptoms are straightforward and visual:

• Paint and Clear Coat Failure: The most common issue is cosmetic. The clear coat may begin to peel, flake, or turn hazy due to sun exposure. The paint color can also fade or become oxidized over time.
• Cracks and Physical Damage: Impacts can cause cracks, chips, or breaks in the spoiler material. Stress cracks often form around the mounting points, which can compromise the spoiler's attachment to the vehicle.
• Loose Mounting or Rattling: The bolts securing the spoiler to the trunk lid can loosen over time, causing the spoiler to vibrate or rattle, especially when closing the trunk or driving at speed. This can also lead to damaged threads or enlarged mounting holes.
• Water Leaks into Trunk: If the seals or gaskets around the mounting bolts fail, or if an installation was done without proper sealing, water can leak through the mounting holes and into the trunk area.

Known Issues, TSBs, and Recalls

There are no recalls or Technical Service Bulletins (TSBs) issued by GM or the NHTSA specifically for the rear spoiler on the 2014-2017 Chevrolet Caprice PPV. While the vehicle itself has been subject to several safety recalls for issues concerning power steering, airbags, and seat belts, the spoiler has not been identified as a safety-related concern.

Buying a Used Rear Spoiler

A used OEM spoiler is an excellent, cost-effective option, but careful inspection is key. Here’s what to look for:

• Check for Cracks: Thoroughly inspect the entire spoiler, paying close attention to the areas around the mounting studs and the thin edges of the spoiler. Minor surface scratches are acceptable, but deep cracks, especially near mounting points, can compromise its structural integrity.
• Assess Paint Condition: Assume you will need to repaint any used spoiler to match your vehicle perfectly. Focus on the underlying condition. Avoid spoilers with widespread peeling or flaking paint, as this indicates poor surface condition that will require more extensive prep work.
• Verify Mounting Studs: Ensure all threaded mounting studs are present, straight, and have clean threads. A stripped or broken stud is difficult to repair and may render the spoiler unusable.
• Confirm Compatibility: Double-check that the spoiler is from a 2011-2017 Caprice PPV or a compatible Holden model (VF/WN). Be aware of different styles; a smaller factory 'lip' spoiler has a different mounting pattern than a larger 'wing' style spoiler.

Installation Guide

Installing a rear spoiler on a Caprice that does not already have one is a moderately difficult task that requires drilling into your trunk lid. Replacing an identical spoiler is much easier.

• Difficulty: 4/5 (New Install); 2/5 (Direct Replacement)
• Estimated Time: 2-3 hours (New Install); 1 hour (Direct Replacement)

Step-by-Step Overview (New Installation)

1. Prepare the Area: Thoroughly clean the trunk lid with soap and water, followed by an alcohol or solvent wipe to ensure it is free of wax and contaminants.
2. Position the Template: Most spoiler kits come with a paper template. Carefully position this on the trunk lid according to the manufacturer's measurements and tape it down securely.
3. Mark and Drill: Use a center punch to mark the center of each hole indicated on the template. Start by drilling small pilot holes (e.g., 1/8"), then step up to the final required drill bit size. This prevents the drill from walking and reduces the chance of damaging the sheet metal.
4. Prevent Rust: After drilling, de-burr the edges of the holes. Apply a zinc-rich primer or clear touch-up paint to the bare metal inside the drilled holes to prevent future rust.
5. Mount the Spoiler: Most spoilers attach with a combination of double-sided tape and bolts. Test fit the spoiler first. Then, peel the backing from the tape, carefully position the spoiler, and insert the bolts through the holes.
6. Secure the Hardware: From inside the trunk, thread on the nuts and washers. Tighten them in a crisscross pattern to ensure even pressure. Do not overtighten. A typical torque specification is around 5-9 N·m (4-7 lb-ft).
7. Final Pressure: Once bolted down, apply firm pressure along the entire surface of the spoiler where it contacts the adhesive tape to ensure a strong bond.

Technical Specifications & Part Numbers

While many styles exist, a common factory option is a flush-mounted spoiler.

• Confirmed OEM Part Number: 92278254 (Flush-Mounted Spoiler Kit in Phantom Black)
• Material: OEM spoilers are typically made of blow-molded plastic. Aftermarket options are available in ABS plastic, polyurethane, and carbon fiber.
• Attachment Type: Bolt-on with adhesive tape assist.
