Here’s a price breakdown for you to get a better idea of what you will be spending. Our standard turn-around time is generally 3-5 business days UNLESS a non-standard service item needs replacing, such as bent or damaged shaft, damaged seal head bearing or wear band, etc. In this case (which is quite often), it depends on vendor availability and shipping time for the new part.

**All shocks must be removed from the vehicle before arriving for service. **
