VANQUISH H10 Optic 89mm Adjustable Progressive Shock Set H10089F/R by GPM  [H10089F/R]

89mm oil-filled progressive shock upgrade

This oil-filled 6061-T6 alloy shock set is a direct aftermarket upgrade for the VANQUISH H10 Optic platform and compatible RTR variants. Each damper ships with a black progressive spring (wire 1.0mm) and an adjustable upper spring retainer to change preload and effective spring rate. The units are factory sealed and supplied with 350cSt silicone oil to deliver consistent damping at model scale.

Mechanical highlights retained from the source parts include an 89mm centre-to-centre length for front or rear fitment, a reinforced shock shaft increased to 3.5mm for better stiffness compared with the original 3.0mm, and a progressive spring profile that gives a compliant initial stroke and firmer ramp-up as load increases. These components are intended as suspension tuning and replacement parts only.

Fitting is simple on the listed VANQUISH H10 Optic kits: remove the original shock, keep any reusable mounting hardware, and install the replacement into the same points. Use the top spring retainer to step in small increments until you reach the balance you want between compliance and control on your usual running surface.

Use these 6061-T6 progressive shocks to fine-tune ride height, spring preload and damping feel on VANQUISH H10 Optic 1/10 cars; adjust the top retainer and trial on your track to dial in handling.
