Infiniti g35 g37 trunk and back bumper

Infiniti G35 G37 Trunk and Rear Bumper for Sale. OEM Exterior Body Panel Replacement.

If you are looking for a clean Infiniti G35 or G37 trunk and rear bumper after a rear-end collision, parking lot damage, or years of surface wear that bodywork alone cannot fix, sourcing verified OEM panels from a low mileage donor car is the most practical path to a factory-correct repair. At McClain Auto Part, we have been sourcing and selling used OEM body panels out of Cleveland, Ohio since 2009. The G35 and G37 trunk lid and rear bumper cover are two of the most consistently requested exterior panels we carry in the Infiniti platform.

G35 and G37 owners come to us for a few reasons. Some deal with a cracked or buckled trunk lid after a rear impact that bent the panel beyond what straightening can correct. Others have a rear bumper cover that is cracked, broken at the mounting tabs, or has paint that has faded or peeled beyond what a respray can fix cleanly. In addition, a group of enthusiasts building restomod or track-prepared G35 and G37 coupes and sedans sources clean OEM panels as a foundation for custom bodywork, paint, or aero modification.

Whatever the situation, the goal is the same. Clean, structurally sound G35 G37 exterior body panels that give you the right starting point for a factory-correct repair or a custom build.

G35 and G37 Body Panel Fitment Overview

The Infiniti G35 and G37 share a common platform lineage but use different exterior body panels that do not interchange between generations. Understanding which generation your car belongs to and which body style you have is the first step before ordering any exterior panel.

G35 Versus G37 Generation Differences

The G35 ran from 2003 to 2007 in coupe form and 2003 to 2006 in sedan form. The G37 replaced it starting in 2008 for the coupe and 2009 for the sedan, running through 2013 in most markets. The trunk lid and rear bumper cover are model-year and body-style specific. A G35 coupe trunk lid does not fit a G37 coupe. A G37 sedan rear bumper does not fit a G37 coupe. Confirm your specific model year and body style before ordering.

Coupe Versus Sedan Fitment

The G35 and G37 coupe and sedan use completely different trunk lids and rear bumper covers. The coupe has a shorter, more steeply raked trunk lid that follows the roofline of the two-door body. The sedan uses a longer, flatter trunk lid specific to the four-door body. The rear bumper covers also differ in width, profile, and mounting configuration between coupe and sedan. Confirm your body style before ordering.

Sport Versus Base Trim Bumper Differences

On some G37 applications, the Sport trim rear bumper cover has different lower fascia geometry and diffuser styling compared to the base trim bumper. These differences can affect fitment if you are replacing a Sport trim bumper with a base trim unit or vice versa. Confirm your original trim level before ordering.

Installation Notes

Trunk Lid Alignment

OEM donor trunk lids fit to factory tolerances when installed on a structurally correct G35 or G37 chassis. After installation, adjust the hinge mounting points for proper gap alignment with the rear quarter panels and rear bumper cover before final torque. Trunk gap consistency on the G35 and G37 depends on hinge adjustment and latch height. Take time with alignment before committing to paint or bodywork.

Rear Bumper Cover Installation

The G35 and G37 rear bumper cover mounts to the bumper reinforcement bar and lower quarter panel extensions using a combination of clips, bolts, and push-pin fasteners. Replace any clips or fasteners that break during removal of the original bumper. Using worn or broken clips results in loose fitment and panel gaps. Quality OEM-spec replacement clips are available from multiple suppliers and inexpensive to source before installation.

Paint Matching

OEM donor panels arrive in the original donor vehicle paint color, which rarely matches your car exactly. Plan for a respray on any panel you source from a donor vehicle. Surface preparation before painting is the same as any other body panel. Sand, prime with an epoxy primer on bare metal areas, and confirm panel straightness and alignment before the final color coat.

Spoiler and Trim Transfer

If your original trunk lid has a factory lip spoiler, confirm the donor unit also has a spoiler mount or plan to transfer your original spoiler to the replacement trunk lid. Spoiler mount hole locations vary between trim levels and model years. Confirm compatibility before attempting a transfer.
