Fitment Notes

• Standard Suspension (non-Sport Package) only - this spring is for E46 models without the factory Sport Package. E46s with Sport Package suspension use a different rear spring (Bilstein 38-233715). Confirm your vehicle's suspension specification before ordering.
• Rear position, left or right - the same spring fits both sides. Sold individually. Order 2 for a complete rear axle replacement, which is strongly recommended when replacing due to age or failure.
• Replaces BMW OEM part number 33 53 1 095 692.
• When replacing rear coil springs, it is also advisable to inspect and replace related components such as rear shock absorbers, spring pads, and strut mounts as needed.
• Black powdercoat finish.

Features

• Bilstein B3 OE Replacement - manufactured to precisely match original equipment dimensions, spring rate, and design type (including miniblock or central force coil geometry as required for the E46 rear axle). Restores factory ride height, handling, and suspension system safety to BMW specifications.
• Manufactured from high-quality spring steel using Bilstein's advanced production and heat-treatment processes for consistent spring rate, long service life, and resistance to fatigue and sag.
• Direct OE replacement - no modification required. Bolt-in fitment using factory hardware and mounts.
• Designed to work in harmony with Bilstein B4 and B6 rear shock absorbers for a complete, balanced OE-specification suspension restoration.
• Black powdercoat finish for corrosion resistance.

Product Description

The Bilstein 38-129230 is a B3 OE Replacement rear coil spring for the BMW 3 Series E46 (all body styles - Sedan, Coupe, Convertible, and Touring/Wagon) with standard (non-Sport Package) suspension. It is a direct OE replacement for the factory rear spring, manufactured to the same dimensions, spring rate, and coil geometry as the original BMW part (cross-reference: BMW 33 53 1 095 692), restoring factory ride height, handling precision, and suspension system integrity.

E46 rear coil springs are a common wear and replacement item - symptoms of failed or sagging springs include reduced ride height, excessive body roll, uneven tire wear, and harsh or knocking suspension behavior. The Bilstein B3 uses high-quality spring steel and advanced heat treatment to deliver consistent spring rate and long service life. Note that E46 models equipped with the Sport Package use a different rear spring specification - confirm your vehicle's suspension before ordering. Replacement in pairs (both rear springs simultaneously) is strongly recommended. Backed by Bilstein's 2-year warranty against defects in design, materials, and workmanship.
