GPM H10089FR 89mm 6061-T6 Adjustable Progressive Shocks  [H10089FR]

Precision 89mm alloy shocks for 1/10 H10 Optic tuning

These GPM H10089FR shocks are 89mm aluminium units made as direct front and rear replacements for 1/10 H10 Optic cars. Machined from 6061-T6, each shock arrives prefilled with 350cSt silicone oil and fitted with a black progressive spring with 1.0mm wire. The stroke shaft is increased to a 3.5mm diameter to reduce flex, and the top spring retainer is adjustable to change preload and perceived damping response.

Fit them when you need more consistent travel and easier setup: alter spring preload to set ride height and initial compliance, use the progressive spring to handle mixed surfaces, and inspect seals routinely to keep the oil and damping consistent. These parts are intended for RC-scale setup and routine maintenance only.

Use these 6061-T6 alloy shocks to replace worn factory units or to refine H10 Optic suspension settings; the adjustable retainer and progressive springs help with routine tuning from track to rough surfaces.
