IMPORTANT! READ THIS FIRST!
Installation of shock absorbers or other suspension components requires
special tools and expert knowledge. Accordingly, installation of all BILSTEIN
products must be performed by a professional automotive suspension technician.
When replacing other brands, BILSTEIN shock absorbers or other suspension
components should always be installed as a set. All BILSTEIN products must
only be used for the specific, intended application as indicated in the
application guide. Any use of any BILSTEIN product other than for its intended
use may result in serious bodily injury or death.
Always use a chassis hoist for the installation of BILSTEIN products and make
certain that the raised vehicle is securely attached to the hoist and/or
supported to prevent the vehicle from slipping, falling, or moving during the
installation process.
If you install any BILSTEIN product without the necessary special tools,
expertise, and chassis hoist, you may subject yourself to the risk of serious
bodily injury or death.
BILSTEIN shock absorbers are gas-filled and are highly pressurized.
- Never place any BILSTEIN shock absorbers in a vise or use a clamp on any BILSTEIN shock absorber.
- Never apply heat near any BILSTEIN shock absorber.
- Never attempt to open or repair any BILSTEIN product, in order to prevent serious bodily injury or death.
Any attempt to misuse, misapply, modify, or tamper with any BILSTEIN
suspension product voids any warranty and may result in serious bodily injury
or death.
While installing any BILSTEIN product:
- Do not use impact tools for loosening or tightening fasteners, because this may destroy the screw threads.
- Self-locking fasteners must only be used once!
- Reuse original equipment components only if they are in good condition, otherwise replace them with new components.
- Never remove the slight film of oil on the shock absorber piston rod and seal.
- All mounting fasteners for shock absorbers and other suspension components must be securely tightened before tension is placed on the suspension system, unless otherwise specified in the manufacturer’s service manual or in this instruction.
After installing any BILSTEIN product:
- The suspension caster and camber must be checked and/or adjusted to comply with the vehicle manufacturer’s specifications.
- The (load dependent) brake compensator and the anti-lock brake system must be checked and/or reset to comply with the vehicle manufacturer’s specifications.
- The headlight aim must be checked and adjusted. Or, if applicable, adaptive headlights must be checked and recalibrated to comply with the vehicle manufacturer’s specifications.
- If applicable, any/all Advanced Driver Assistance Systems (ADAS) must be checked and recalibrated to comply with the vehicle manufacturer’s specifications.
CAUTION for COILOVER TYPE SUSPENSIONS!!!
If disassembling a coilover type suspension, refer to the vehicle
manufacturer’s service manual for proper procedures. The coil spring is
preloaded and must be compressed with a spring compressor to release load
before the upper mount is disassembled. Failure to follow the vehicle
manufacturer’s procedures may cause serious injury or death, and may damage
the vehicle.
MPORTANT!!!
This BILSTEIN product may or may not be compatible with non-BILSTEIN aftermarket products and/or vehicle modifications. It is the responsibility of the professional automotive suspension technician performing the installation to identify any non-OEM components and/or modifications on the vehicle that may interact with the suspension system. These must be evaluated for any potential physical static or dynamic interference with and/or effect on the function of this BILSTEIN product.
IMPORTANT:
PLACE CIRCLIP IN APPROPRIATE GROOVE TO ADJUST RIDE HEIGHT (B8 5100 ONLY).
Use appropriate tools to move the circlip. Ensure that the circlip is fully
seated in the groove after moving it (you should be able to rotate it manually
in the groove). Install the spring seat in the direction shown only. The
circlip must fit completely in the groove inside the spring seat (DETAIL A).
Improper installation will cause permanent damage to the shock!
| Circlip Location | B8 5100 Typical Lift Heights** |
|---|---|
| #6 | 2.3″ |
| #5 | 1.8” |
| #4 | 1.3” |
| #3 | 0.8” |
| #2 | 0.4” |
| #1 | Stock |
** Ride heights indicated are typical. Actual ride height is influenced by
which factory suspension the vehicle is equipped with and its condition;
optional equipment and accessories on your vehicle, and other vehicle
modifications such as replacement coil springs, wheel and tire combinations,
etc.
Modifying/lifting the suspension to your vehicle may raise its center of
gravity and may make it more susceptible to loss of control and/or rollover,
which may result in death or serious injury. We strongly recommend that you
offset the loss of rollover resistance as much as possible by increasing tire
track width, and that you equip the vehicle with a functional roll bar and
cage system.
Wear seat belts and shoulder harnesses at all times, and avoid situations
where a side rollover may occur.
Instructions for disassembly of OE shock absorber module:
A. Remove the existing shock and spring unit from the vehicle following all
procedures in the vehicle manufacturer’s service manual.
B. Note the clocking of the lower T bar mount relative to the studs on the
upper mount as shown in Figure 1 (important for reassembly). C. Using an
appropriate spring compressor, compress the spring until it can be rotated
freely by hand. Then, disassemble the shock and spring unit.
D. Remove the OEM shock.
Instructions for assembly of Bilstein B6 4600 or B8 5100 Series shock absorber
module:
B6 4600: Skip step E.
B8 5100: Skip step E if using circlip locations #1-#2. If using circlip
locations #3-#6, continue to step E. Trimming the OEM dust boot is only
necessary if circlip locations #3#6 are being used.
E. Using scissors, cut the OEM dust boot on the dotted line shown below in
Figure 2: The result should look as depicted below in Figure 3:
F. Install the supplied spring seat followed by the supplied spring seat
isolator onto the new Bilstein shock body as shown. Orient the spring seat and
spring seat isolator in the direction shown only. Ensure that the groove
inside the spring seat fits over the circlip on the shock body [see page 2
(DETAIL A)]. Improper installation will cause permanent damage to the shock.
G. Install the supplied bump stop cap onto the shock body as shown in Figure
5.
H. Using an appropriate spring compressor, compress the OEM spring and
assemble it with the new Bilstein shock. Ensure that the OEM coil spring is
installed in the direction shown only. Refer to Figure 1.
I. Install the OEM top hat assembly (which includes the OEM dust boot, OEM top
mount plate, and OEM jounce bumper) over the threaded stem on the new Bilstein
shock and on top of the spring. Refer to Figure 5.
J. Rotate the coil spring until the end of the top coil is seated into the OEM
dust boot as shown in Figure 4.
K. Rotate the shock so the lower T bar mount is aligned with the upper mount
studs as noted in step B and shown in Figure 1.
L. Install the provided new flange lock nut and tighten to 45 Nm (34 lb/ft).
Use an 8mm wrench to keep the piston rod from rotating while torqueing the
lock nut.
**DO NOT USE AN IMPACT WRENCH TO TIGHTEN THE LOCK NUT! **
M. Release the spring compressor while ensuring that the end of the top coil
remains seated in the OEM top hat assembly.
N. Install the assembly on to the vehicle and tighten all fasteners to the
vehicle manufacturer’s specifications- with exception to the lower T bar
bolts. Install the OEM lower T bar bolts up through the control arm and T bar.
Then install the Bilstein supplied flange lock nuts on to the OEM T-Bar bolts
and tighten the supplied flange lock nuts to 72 Nm (53 lb/ft). Do not re-use
the original lock nuts. This completes the installation.
O. Check wheel alignment. If necessary, adjust to the vehicle manufacturer’s
specifications.
