Bilstein 19-240084 B4 OE Replacement Rear Shock Absorber for 2014-2019 BMW i3

Vehicle Fitment

• 2014-2019 BMW i3 (I01 Chassis, RWD) - All Trims including i3 and i3 REx (range extender)

Fitment Notes

• Rear position only - driver or passenger side; sold individually (one shock per order); order two for a complete rear pair
• RWD (rear-wheel drive) applications - the BMW i3 is a rear-motor, rear-wheel-drive platform; no AWD variant exists for this generation
• Fits both the standard i3 BEV (battery electric vehicle) and the i3 REx (range extender) variants - both share the same I01 chassis rear suspension geometry
• OEM stock-height replacement application - designed for vehicles at factory ride height
• Not recommended for use with lowering springs - designed to work with factory BMW i3 spring components only
• Factory shock mounting bolts are reused during installation - all necessary washers, bushings, and hardware included; mounting plates sold separately if required
• 2020-2021 BMW i3 owners: verify fitment with ShockWarehouse or BimmerWorld - a different damper part number may apply for later production years

Features

• Bilstein B4 OE Replacement product line - engineered to restore the BMW i3's factory ride quality, handling precision, and safety to OEM standards or better
• Twin-tube gas pressure design - delivers consistent damping performance, excellent ride comfort, and long-term durability optimized for the i3's lightweight carbon fiber reinforced plastic (CFRP) passenger cell and aluminum Life module construction
• Gas pressure technology prevents oil foaming under repeated or sustained compression cycles - maintains consistent damping force regardless of road conditions or temperature
• Precision-engineered to match the BMW I01 i3's factory rear suspension geometry, spring rates, and ride height
• Bilstein is an OEM supplier to BMW - the same engineering standards and quality control applied to every B4 OE replacement unit
• All necessary installation hardware included - washers, bushings, and clamps; factory mounting bolts are reused

Product Description

The Bilstein 19-240084 is a B4 OE Replacement rear shock absorber designed as a direct fitment for the 2014-2019 BMW i3 (I01 chassis) in both BEV and REx variants. It is a twin-tube gas pressure unit engineered to restore the i3's factory ride quality and handling - meeting or exceeding BMW's OEM standards as a direct replacement rear damper for this uniquely engineered electric vehicle platform.

The BMW i3's I01 architecture pairs a lightweight carbon fiber reinforced plastic (CFRP) passenger cell with an aluminum Life module, resulting in a vehicle that is significantly lighter than conventional cars of similar size - a characteristic that demands precisely calibrated damper tuning to maintain the composure and ride quality BMW engineered. The Bilstein B4's twin-tube gas pressure design provides consistent, temperature-stable damping that preserves the i3's factory-intended ride behavior. All installation hardware is included; factory mounting bolts are reused. Sold individually - order two for a complete rear pair. Not recommended for use with lowering springs.
