BMW E81 / E82 / E87 / E88 1 Series & E90 / E91 / E92 / E93 3 Series Rear Shock Mount Set 4-Piece (Replaces 33506771738 / 33506771737)

Restore proper rear suspension mounting and eliminate clunking, knocking, and harsh ride symptoms on your BMW E8X or E9X chassis with this premium rear shock mount set, manufactured from durable rubber and metal construction for reliable factory-spec replacement. The factory rear shock mounts on E81, E82, E87, E88, E90, E91, E92, and E93 chassis are notorious wear components that develop the characteristic clunking and knocking sounds, harsh ride quality, and compromised handling characteristics as the rubber isolators age and tear. When the rear shock mounts fail, you'll typically experience clunking noises over bumps, popping sounds during weight transfer, deteriorated ride quality, and inconsistent rear suspension response under cornering loads. This 4-piece replacement set restores proper rear shock mounting performance with rubber and metal construction matching factory specifications, eliminating the failure-mode symptoms that plague aged BMW E8X / E9X rear suspensions.

Features:

• Direct OE replacement design – manufactured to factory specifications matching original equipment part numbers 33506771738 and 33506771737
• Premium rubber and metal construction – delivers reliable isolation between the rear shock and chassis mounting points
• 4-piece complete set – sufficient hardware for one complete rear shock mount replacement (both rear shocks)
• Restores proper ride quality – eliminates the harsh, jarring ride that develops when factory mounts fail
• Resolves clunking and knocking noises – addresses one of the most common BMW E8X / E9X rear suspension complaints
• Wide chassis compatibility – fits the entire E8X / E9X chassis range across multiple body styles
• Critical preventive maintenance – addresses a known wear point on aged BMW chassis

Contents:

• 4x Rear Shock Mounts

Benefits:

• Eliminates the clunking, knocking, and popping sounds that develop as factory rear shock mounts age and deteriorate – one of the most common rear suspension complaints on BMW E8X / E9X chassis
• Restores proper ride quality – correctly functioning shock mounts ensure proper damping isolation between the suspension and chassis
• Improves handling consistency – worn shock mounts allow the rear shock to move within the chassis under load, causing inconsistent damping response and unpredictable handling
• Resolves common BMW rear suspension symptoms – including clunking over bumps, harsh ride quality, popping during cornering, and rear-end inconsistency
• Direct factory-spec replacement ensures correct fitment and performance restoration
• Critical preventive maintenance for any high-mileage BMW E8X / E9X – shock mount wear is universal on aged chassis
• Significant cost savings compared to BMW dealer pricing for the same factory replacement parts
• Wide cross-platform compatibility makes this versatile for BMW enthusiasts who manage multiple E8X / E9X chassis or workshops servicing diverse BMW models
• Complete 4-piece set provides everything needed for full rear shock mount service – no additional sourcing required

Common Symptoms of Failed Rear Shock Mounts:

• Clunking or knocking sounds from the rear over bumps or rough roads
• Popping noises during weight transfer (acceleration, braking, cornering)
• Harsh, jarring ride quality on otherwise smooth roads
• Inconsistent rear suspension response under cornering loads
• Rattling or loose feeling from the rear suspension area
• Visible wear, cracking, or deformation of factory rubber mount components during inspection

Installation Notes:

• Part number verification: Confirm your factory rear shock mounts use OE part numbers 33506771738 or 33506771737 before ordering – verify by inspecting existing mounts
• Replace in pairs minimum: Always replace rear shock mounts in pairs (left and right) to maintain consistent rear suspension geometry – this complete 4-piece set provides hardware for both rear shocks
• Properly support the rear of the vehicle on jack stands rated for the vehicle weight before beginning installation – never work under a vehicle supported only by a jack
• Allow the rear suspension to hang freely or position at static loaded ride height per service procedure for your specific BMW chassis
• Carefully remove the rear shock absorbers from the vehicle following factory service procedure – consult vehicle service documentation for proper removal sequence
• Inspect the rear shock absorbers during installation – worn or damaged shocks should be replaced simultaneously with the new mounts for optimal performance restoration
• Replace any associated hardware (bolts, washers, retaining clips) that shows wear or damage
• Install the new shock mounts onto the rear shock absorbers following factory orientation
• Reinstall the rear shock assemblies into the vehicle using factory torque specifications
• Tighten all suspension hardware to factory torque specifications using a calibrated torque wrench
• Test the suspension by bouncing the rear of the vehicle to verify proper damping operation
• Test drive at low speeds first to verify resolved symptoms (no clunking, smooth ride, consistent rear-end response)
• Inspect installation periodically for any signs of wear or loosening
• Professional installation strongly recommended unless you have experience with BMW rear suspension service procedures
• If unsure about compatibility with your specific BMW variant, contact our team with your year, model, chassis code, and factory shock mount part numbers before ordering

Warranty:

• 12-month standard warranty from date of purchase
