26×9.0 / 26×11.5 Forged Two-Piece Wheels for 1988 Chevrolet Monte Carlo (GM G-Body) – Gold Electroplated Center with Brushed Barrel and Polished Lip 5×120.65

Engineering Notes

XINGTU’s engineers want to highlight three details that define this build.

Staggered Two-Piece Forged Construction

The Monte Carlo 26 inch forged wheels feature an intricately machined split-spoke center, with slender branching sections extending from the hub toward the outer rim. The layered spoke arrangement creates a detailed, open wheel face, while the exposed perimeter hardware highlights the two-piece construction.

Each wheel consists of a separately machined forged aluminum center and barrel, joined through structural assembly hardware. This arrangement accommodates the different front and rear widths while preserving the same split-spoke styling across the set.

The front wheels measure 26×9.0, while the rear wheels use a substantially wider 26×11.5 configuration. Combined with the different mounting offsets, the rear barrel creates a much deeper outer-lip profile than the front.

The finished front wheel weighs 20.5 kg and the rear weighs 23.3 kg, with a stated load rating of 750 kg per wheel.

Gold Electroplating & Contrasting Aluminum Finishes

The wheel combines three distinct metallic finishes: a gold electroplated center, a brushed silver barrel and a polished outer lip. Each surface contributes a different texture and level of reflection to the finished two-piece assembly.

Gold electroplating gives the intricately machined split spokes a bright metallic appearance. The branching spoke sections, narrow openings and recessed contours require careful polishing and surface preparation before plating to maintain consistent reflections across the detailed wheel face.

The barrel retains a directional brushed aluminum texture, providing a softer metallic contrast against the gold center. The outer lip receives additional polishing, creating a brighter reflective edge that emphasizes the wheel's substantial depth.

Separate surface preparation and finishing allow the three metallic treatments to remain clearly defined. Gold electroplating, barrel brushing, lip polishing and final two-piece assembly form part of the recorded 45-day production schedule.

Deep-Lip Geometry for the Chevrolet Monte Carlo

Produced for a 1988 Chevrolet Monte Carlo (GM G-Body), the wheel set features a 26×9.0 front configuration with an ET-10 offset and a 26×11.5 rear configuration with an ET-42 offset. Both wheels use a 5×120.65 bolt pattern and 70.3 mm center bore.

The wider rear barrel and more negative offset position the mounting face farther inward relative to the outer rim, creating the pronounced rear-lip depth visible in the finished design. The front wheel retains a shallower profile while maintaining the same gold split-spoke pattern.

These dimensions define the completed production configuration rather than a universal replacement specification for the G-Body platform. The oversized diameter and negative offsets require appropriate clearance around the suspension, brakes, steering components and bodywork.

The lug-seat type is not identified in the production record and requires confirmation before installation. The 5×120.65 bolt pattern corresponds to 5×4.75 inches and should not be confused with 5×120.

From Design to Delivery

• CMM dimensional inspection of PCD, center bore and offset
• Front and rear wheel specifications checked separately
• Center-to-barrel assembly and connecting hardware inspected
• Radial and lateral runout inspected after final assembly
• Airtightness checked before tire installation
• Dynamic balancing completed for every wheel
• Gold electroplating, brushed barrel and polished lip visually inspected under controlled lighting

Result

The completed Monte Carlo wheel set features an intricate gold split-spoke pattern framed by brushed silver barrels and highly reflective polished lips. The detailed spoke geometry creates an open, layered appearance, while the contrasting finishes distinguish the forged centers from the surrounding rim surfaces.

The difference between the front and rear wheels is particularly noticeable in their outer-lip depth. The wider 26×11.5 rear wheels create a more pronounced deep-dish profile, while the 26×9.0 fronts retain the same spoke design with a shallower rim. Exposed assembly hardware completes the distinctive appearance of the two-piece forged construction.

Front & Rear Wheel Specifications

The completed set features 26×9.0 ET-10 front wheels and 26×11.5 ET-42 rear wheels, with a shared 5×120.65 bolt pattern and 70.3 mm center bore. The staggered widths and negative offsets create different front and rear lip depths while maintaining the same 26-inch diameter.

Forged Two-Piece Assembly

Each wheel combines a forged aluminum split-spoke center with a separately finished barrel, secured through structural assembly hardware. The front and rear wheels weigh 20.5 kg and 23.3 kg respectively, with a stated load rating of 750 kg per wheel. Gold electroplating, directional barrel brushing and polished outer lips complete the design.

Vehicle Fitment & Mounting

The oversized dimensions represent the featured 1988 Chevrolet Monte Carlo G-Body configuration. The 5×120.65 PCD must match the vehicle's mounting pattern, and the lug-seat type requires confirmation. Brake, suspension, steering, tire and fender clearances should be checked carefully, particularly around the wide ET-42 rear wheels.

1. Will These 26-Inch Forged Wheels Fit Every Chevrolet Monte Carlo G-Body?

The featured wheels were produced for a customized 1988 Chevrolet Monte Carlo G-Body. Their 26-inch diameter, staggered widths and negative offsets represent a specific production configuration rather than universal replacement dimensions. Actual fitment depends on the vehicle's suspension, brakes, steering clearance, bodywork and selected tires.

2. What Are the Front and Rear Wheel Specifications?

The front wheels measure 26×9.0 with an ET-10 offset, while the rear wheels measure 26×11.5 with an ET-42 offset. Both use a 5×120.65 bolt pattern and 70.3 mm center bore. The recorded weights are 20.5 kg at the front and 23.3 kg at the rear, with a stated load rating of 750 kg per wheel.

3. How Are These Two-Piece Forged Wheels Constructed?

Each wheel consists of a forged aluminum center and a separate barrel joined through structural assembly hardware. This construction accommodates different barrel widths and mounting positions while maintaining the same gold split-spoke design across the front and rear wheels.

4. Why Do the Rear Wheels Have a Deeper Outer Lip?

The rear wheels use a wider 26×11.5 barrel and an ET-42 offset, compared with the front wheels' 26×9.0 width and ET-10 offset. These dimensions create a more pronounced outer-lip profile on the rear wheels, giving the staggered set its distinctive appearance.

5. Is the Gold Finish Painted or Electroplated?

The forged centers receive gold electroplating rather than conventional gold-colored paint. The barrels retain a brushed silver finish, while the outer lips undergo separate polishing to create a brighter reflective surface. The three finishes highlight different sections of the two-piece assembly.

6. What Mounting Hardware Is Required?

The wheels feature a 5×120.65 PCD, equivalent to a 5×4.75-inch bolt pattern, and a 70.3 mm center bore. The lug-seat type is not stated in the production record, so compatible wheel nuts must be confirmed before installation. The 5×120.65 and 5×120 patterns are not interchangeable.

7. How Long Does Production Take?

The recorded production schedule is 45 days, covering forged center machining, barrel preparation, gold electroplating, barrel brushing, lip polishing, two-piece assembly, airtightness inspection and dynamic balancing. Shipping transit and additional design revisions are separate from the production schedule.
