R12/GT Rear Damper Upgrade X Set - YOKR12-37 Yokomo  [YOKR12-37]

Durable rear dampers for regular track use

The Yokomo YOKR12-37 X Rear Shock Set is supplied as an aftermarket rear damper kit aimed at R12/GT chassis. This summary highlights reliability, routine service pointers, and the kit's role in steadying rear behaviour under frequent running instead of speculating on unpublished details.

The part is intended for models listed as R12/GT and functions as a direct replacement or an upgrade to enhance rear suspension durability and control. Typical installation replaces the factory rear dampers using the same rear tower and lower mounting points; always inspect mounting hardware and clearances before final assembly.

Tuning-wise, rear shocks affect body roll, traction transfer, and rear compliance under load. Use the set to stabilise damping response and maintain consistent ride height in combination with springs and sway bar choices. Perform incremental adjustments and test across repeated runs for reliable comparisons.

Maintenance recommendations: regularly examine seals and shaft condition, refresh shock oil with products suitable for 1/12 scale dampers, and replace worn seals promptly to avoid performance drift. This is a model-scale accessory and not for full-size vehicle use.

A practical rear shock kit for R12/GT racers seeking consistent on-track durability; match with proper springs and service schedule for best results.
