The H10049FR upper link bar set is machined from 7075-T6 aluminum with an integrated profile that increases stiffness over common stamped or molded pieces. The curved profile around the steel pivot-ball seats helps keep the pivot balls seated while preserving the factory mounting points and angles.
Provided dimensions can be used to confirm fit: front upper link center-to-center is 139 mm with a cross-section thickness of 4.0 mm; rear upper link center-to-center is 129 mm with a thickness of 5.0 mm. This set replaces factory part number IRC00307 and retains the original pivot-ball spacing so it fits the same posts as the stock links.
Switching to 7075-T6 alloy for the upper links raises longitudinal and torsional stiffness at the link plane. For an electric buggy chassis this tends to stabilise the link plane under load, producing more consistent steering inputs and steadier responses across rough terrain. The integrated design reduces flex paths common to multi-piece links while leaving pivot geometry unchanged.
Intended for the VANQUISH product line H10 Optic variants. Verify fit against the models below before installation:
The package contains four upper link bars supplied as a set. The original name and part reference is IRC00307. The manufacturer suggests using a medium-strength screw adhesive to help keep fasteners secure during use.
The GPM H10049FR upper link bar set is a direct-fit, 7075-T6 alloy replacement for H10 Optic platforms, offering firmer link support and consistent pivot retention for hobbyists performing component upgrades or restorations.
