Introduction
The G800 is the wide body language most owners picture when they imagine an aggressive G-Class: bold, muscular width with curves that flow — aggressive enough to command attention, refined enough to still read as a Mercedes. Our G800 style carbon fiber wide body kit delivers that identity for W463A, W464, and W465 models in genuine dry carbon, and it remains the most popular wide body direction we supply.
This guide covers what the G800 style kit includes, how it differs from sharper styles like the G900, who it suits best, and the practical planning every owner should do before committing to wide body.
What the Kit Includes
The G800 style carbon fiber wide body kit is a complete transformation package:
- Front bumper with integrated splitter: the bold front with a sculpted splitter and duct openings
- Wide fender flares (front and rear): the signature G800 curves — wider arches with flowing lines that blend into the body
- Side skirts with steps: the connecting profile with practical step surfaces
- Rear bumper with diffuser: the rear treatment with diffuser elements and exhaust openings
- Matching roof spoiler: the finishing line of the G800 profile
The kit is engineered for direct bolt-on fitment on W463A, W464, and W465 — no cutting, no welding, with factory mounting points and reversible installation.
The G800 Character
The G800 direction is defined by its curves:
- Bold but smooth: the flares flow into the body rather than cutting hard angles — aggressive width without the motorsport sharpness of the G900
- Factory-adjacent premium: the styling language feels like a factory flagship rather than a racing build, which is why it suits owners who want presence without the race-car statement
- The classic choice: if you are undecided between wide body styles, the G800 direction is the safe-but-spectacular middle — our G800 vs G900 vs G63 wide body comparison shows the styles side by side
Dry Carbon Construction
The kit uses genuine dry carbon fiber with a deep-gloss 2×2 twill finish:
- Weight savings: dry carbon keeps the added mass low — important on the heavy G63 platform
- Premium finish: UV-stabilized clear coat over autoclave-cured pre-preg material
- Quality verification: use our guide on detecting quality dry carbon fiber parts to judge the kit when it arrives
Planning the Wide Body Project
- Wheel fitment is the critical decision: the flares require 10-20mm wider track per side. Plan wheels and tires together with the kit — our wheels and tires upgrade guide covers the fitment math
- Professional installation: budget 3-5 shop days for a full kit, including fitment and alignment. Run our wide body pre-installation checklist before installation begins
- Protection program: wide body panels sit in the impact zone — our wide body maintenance guide covers PPF, ceramic coating, and stone chip repair
- Budget: kit + install + wheels is the full project. Our wide body installation cost guide breaks down every cost layer so there are no surprises
Frequently Asked Questions
Does the kit fit W464 and W465?
The G800 style kit is available for W463A, W464, and W465 models with direct bolt-on fitment. Confirm the model-year match when ordering.
Is it reversible?
Yes — the kit uses factory mounting points with no cutting or welding. The factory parts can be refitted at any time, which also protects resale value (see our resale value guide).
What wheels should I run?
Flare width typically calls for 10-20mm wider track per side. Match your wheel offset and width to the flares — see our wheels and tires upgrade guide.
How long does installation take?
3-5 shop days including fitment, sensor integration, and alignment at a specialist installer.
G800 or G900?
G800 is bold but flowing and refined; G900 is sharper and more aggressive. The comparison guide breaks down both directions in detail.
