GPM H10089FR 6061-T6 89mm Adjustable Progressive Shock Set  [H10089FR]

Purpose-built 89mm alloy shocks for 1/10 H10 Optic

These GPM H10089FR shocks are 89mm aluminium units designed as direct front and rear replacements for 1/10 H10 Optic vehicles. Constructed from 6061-T6 alloy, each shock comes prefilled with 350cSt silicone oil and fitted with a black progressive spring (1.0mm wire). The shock shaft has been increased to 3.5mm diameter for added rigidity, while the top spring retainer is adjustable to alter spring preload and perceived damping stiffness.

Use them where improved suspension tuning and consistent stroke control are needed: change spring preload for ride-height and initial compliance adjustments, exploit the progressive spring behaviour for mixed-surface running, and check seals regularly to retain oil fill and damping characteristics. They are intended for RC-scale setup and maintenance only.

Fit these 6061-T6 alloy shocks when replacing factory units or refining H10 Optic suspension setup; their adjustable retainer and progressive springs assist routine tuning and track-to-field configuration.
