OWNER REBUILDABLE
The B8 8125 Series are fully owner rebuildable and revalvable. Any component can be purchased
through a BILSTEIN dealer or direct from BILSTEIN. Owner rebuildable shocks can also be revalved and
serviced by BILSTEIN. BILSTEIN O-Road Department can be contacted direct at 1-800-537-1085 for
parts, service or technical questions.
GAS PRESSURE
-
USE NITROGEN ONLY!
B8 8125 Series uses nitrogen which requires regular service. Failure to service your shock will reduce the
life span and damage the shock absorber.
If the suspension begins to feel soft, you may need to increase nitrogen pressure. Nitrogen can be ser-
viced through a Schrader
TM
valve located on the reservoir end cap. A BILSTEIN Gas Filling Tool (Part
#193000) is available. Please contact a BILSTEIN dealer for more details. Nitrogen bottles typically can
be purchased at a welding supply store.
• B8 8125 Series are delivered with 200 PSI nitrogen pressure.
• Proper ll level range is from 180-200 PSI.
INSTALLATION
B8 8125 Series are not intended for use on any OEM applications, and will not t directly in OEM mount-
ing locations. Incorrect installation can lead to the failure of this product. The user is responsible for
determining the suitability of these products. Below are a few tips:
• A limit strap is strongly recommended on any high-speed application where suspension oscillations
to “full droop” are a common occurrence.
• The B8 8125 Series are supplied with (4) heim spacers, of which (1) must be placed on both sides
of the spherical bearing (top and bottom). The purpose of these spacers is to allow the spherical
bearing to articulate as the shock cycles through its travel. It is very important that the heim spac-
ers, or any part of the mount brackets, etc., do not contact the end loop during operation. Any
interference with the free movement of the bearings may result in a bent or broken piston rod.
• It is very important to cycle the suspension to “full bump” and “full droop” before operating the
vehicle with this product. Failure can occur if the shock body comes in contact with the chassis, tire
and wheel, or suspension of the vehicle.
GETTING
STARTED.
Prior to getting started, please read the information below as it is important to maintaining the life
and performance of your shocks. Do not attempt to disassemble or assemble your shocks without
proper tools or technical knowledge.
