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.
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.
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.
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 package contains four upper link bars supplied as a set. The original name and part reference is IRC00307. A medium-strength screw adhesive is recommended by the manufacturer to help maintain fastener security during use.
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.
