• 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.

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.

IMPORTANT
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.

• Remove the shock and spring unit from the vehicle following all procedures in the vehicle manufacturer’s service manual. Note the position of the studs in the upper mount relative to the lower T bar mount (important for reassembly).
• Using an appropriate spring compressor, compress the coil spring until it can be rotated freely by hand. Then disassemble the shock and spring unit.
• Refer to Figure 1 to identify which original parts must be re-used.

If installing B8 5100 Bilstein shock absorbers, proceed with step D. If installing B6 4600 Bilstein shock absorbers (yellow in color), skip to step E.

• B8 5100 only: Select desired lift height by seating the circlip in the appropriate circlip location. Refer to Figure 2 below. 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. (B6 4600s are not ride height adjustable)

Typical lift heights**

Circlip Location| Any Gas engine|

3.0L Diesel

5| 2.1”| 2.5”

4| 1.75”| 2”

3| 1.25”| 1.5”

2| 0.8”| 1”

1| Stock| 0.5”

** Lift heights indicated are typical. Actual lift 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.

Refer to Figure 3 for steps E and F.

• Install the spring seat support (3) on to the shock body (with the smaller end up) such that the groove inside the spring seat support fits over the circlip on the shock body. Install the spring seat support in the direction shown only. The circlip must fit completely in the groove inside spring seat support (see detail). Improper installation will cause permanent damage to the shock!
• Install the original spring seat (9) on to the shock and over the spring seat support (3) in the direction shown only.

Refer to Figure 4 for steps G through K.

• Fit the bump stop (7) over the piston rod, leaving it flush with the top of the chrome length.
• Using an appropriate spring compressor, compress the coil spring (8) and install it on the shock absorber. Align the lower coil end with end of the ramp on the spring seat (9).
• Install the upper mount (6) over the piston rod end and on to the top of the coil spring. Rotate upper mount so that its studs are in their original position relative to the lower T bar mount (as noted in step A). Align the upper coil end of the coil spring with the rubber isolator in the upper mount.
• Install the M12 Washer (1) and the M12x1.5 locknut (2) and tighten to 45 N·m (34 lb·ft). Use an 8mm wrench to prevent the piston rod from rotating while torqueing the locknut.

DO NOT USE AN IMPACT WRENCH TO TIGHTEN THE LOCKNUT!

• Release the spring compressor while ensuring that the ends of the coil spring remain aligned with the spring seat (8) and upper mount (6).

• Apply a high strength, permanent thread locking compound to the bolt thread as shown below

• Install the assembly on to the vehicle and tighten all fasteners to the vehicle manufacturer’s specifications. Install the supplied lower T bar bolts down through the T bar and control arm. Then install the supplied flange lock nuts on to the T bar bolts and tighten the lock nuts to 90 N·m (66 lb·ft). Do not re-use the original lock nuts.

• Check wheel alignment. If necessary, adjust to the vehicle manufacturer’s specifications. This completes the installation.
