GPM Racing 7075-T6 Alloy Upper Link Bar Set for Vanquish 1/10 H10 Optic Kit (H10049FR)

GPM VANQUISH H10 OPTIC H10049FR – 7075-T6 Alloy Upper Link Bar Set for 1/10 Electric Buggy

Material intent and structural design

The H10049FR upper link bar set is machined from 7075-T6 aluminium with an integrated profile intended to stiffen the suspension geometry compared with common stamped or moulded parts. The bars feature an arcuated contour around the steel pivot-ball seats; that curvature aids pivot-ball retention while preserving the factory mounting points and angles.

Dimensional details and factory compatibility

Measured dimensions are supplied for fit verification: front upper link centre-to-centre is 139 mm with a cross-section thickness of 4.0 mm; rear upper link centre-to-centre is 129 mm with a thickness of 5.0 mm. This set replaces factory part number IRC00307 and maintains original pivot-ball spacing so it registers on the same posts used by the stock links.

On-vehicle effects and mechanical character

Specifying 7075-T6 alloy for the upper links increases longitudinal and torsional stiffness at the suspension link plane. In practical chassis terms this results in a more consistent link plane under load and steadier handling inputs through directional changes and irregular terrain. The integrated single-piece profile reduces flex paths that exist in multi-piece link designs while retaining unchanged pivot geometry.

Fitment and model list

The part is intended for the VANQUISH product line H10 Optic variants. Confirm fit against the listed model identifiers when matching parts on an H10 OPTIC platform:

The GPM H10049FR upper link bar set provides a direct-fit, CNC-machined 7075-T6 alloy upgrade for H10 Optic platforms, engineered to increase link-plane rigidity and ensure consistent pivot retention for precision hobbyist applications.

How are the link bars manufactured?

The link bars are CNC machined from 7075-T6 aluminium to achieve consistent section properties and precise pivot-seat geometry for reliable fitment.

Do the bars change pivot spacing or angles?

No. The design retains the original pivot-ball spacing and mounting angles so the parts interface with the stock posts and pivot hardware.

What are the key measured dimensions?

Front upper link centre-to-centre is 139 mm with 4.0 mm thickness; rear upper link centre-to-centre is 129 mm with 5.0 mm thickness, matching the measurements used for fit verification.

Any recommended assembly notes?

Use standard hardware consistent with the stock assembly and consider a medium-strength screw adhesive to maintain torque under vibration and competition conditions. Write Product Review Please sign in your account before you can write any review. Sign In Close
