In some instances a competitor’s part number is longer than required by the vehicle manufacturer and in other cases the KYB product includes a performance improvement. Some KYB shocks include an improved internal bumper stop to cushion extreme movements. This may change the total length before installation; however, the function will be correct when installed on the vehicle.
Some of the reasons include:
- Protect potential damage from full extension of the unit
- Reduce vehicle roll-over effects
On some applications it is necessary to raise the axle or suspension slightly to attach the shock mountings which is also common on many OE components.
