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

Durable 89mm alloy shocks for H10 Optic suspension tuning

The GPM H10089FR series are 89mm aluminium shocks produced as direct front and rear replacements for 1/10 H10 Optic vehicles. Made from 6061-T6 alloy, each unit is prefilled with 350cSt silicone oil and fitted with a black progressive spring (1.0mm wire). The shaft has been enlarged to a 3.5mm diameter for improved stiffness, and the top spring retainer provides adjustable preload and perceived damping adjustment.

Use these when consistent travel and easier setup changes are required: modify spring preload to alter ride height and initial feel, use the progressive spring on variable terrain, and check seals regularly to preserve oil and damping characteristics. These parts are for RC setup and maintenance tasks only.

Install these 6061-T6 alloy shocks to renew factory units or to refine H10 Optic handling; the adjustable retainer and progressive springs support straightforward tuning across environments.
