Rebuild/Upgrade Service for the full set of BMW E88 1-Series.
Send in your cylinders first, or select "Order now with core exchange" to order a set from our inventory. Core exchange orders are subject to a $200 inventory surcharge as well as a $600 refundable core deposit.
Replaced and improved rod seals, piston seals, cap seals, gland seals, wipers, and port seals make these parts better than brand new ones, with an expected service life of 30-50 years under normal circumstances.
No sales tax for orders in the USA
We provide world class technical support
3-year standard warranty (should last decades)
Additional cost applies if the cylinder shafts are scratched, rusted, or there are parts missing or unusual abuse. Please wrap the cylinders in absorbent material and put plastic bags around them, buffer your parcel well inside, ideally double-box, and tape up well.
The most common failure symptom on used BMW E88 cylinders is a leak at one or more of the cylinder seals, causing a leak of hydraulic fluid and loss of pressure in the system.
