Description
Part #: 6375-400
The 63 Series is a sealed non-rebuildable version of the 62 Series. These are most commonly used in coil-over applications on both dirt and asphalt tracks. The twin tube design gives excellent feel and grip across all track conditions, but they really shine when there is a lack of grip. Built as a spec shock that could be used at specific tracks or series, the 63 Series can be used in any late model or modified.
Features:
- Sealed aluminum bodied spec shock
- Excellent choice for sanctioning bodies looking to control cost
- Twin tube design gives excellent feel and grip in many track conditions
- Individually dyno'd and serialized
- Made in the USA
