Detailed Product Description
Is your M-car suffering from front-end clunks or vague steering?
Your upper strut mounts are the pivot point of your entire front suspension. Over time, the rubber insulators harden and the internal bearings wear out. Restore your factory-fresh handling with this KYB Front Upper Strut Mount Set, the choice of enthusiasts for both stock restoration and performance tuning.
KYB is a global leader in OE suspension components. These mounts match the Offset Geometry specific to the 1996–1999 E36 M3 and Z3M, ensuring your caster and camber remain within factory specifications—or allowing for the popular "swapped mount" trick to increase negative camber for track days.
Why Choose KYB Mounts?
-
OE-Grade Durability: Built with high-strength steel and premium rubber compounds to eliminate NVH (Noise, Vibration, and Harshness).
-
Offset Geometry: Includes the specific Left (31332227897) and Right (31332227898) designs required for M-specific suspension geometry.
-
Smoother Steering: High-quality internal bearings ensure the strut pivots effortlessly, reducing steering effort and preventing "spring bind" noises.
-
The "Camber Swap" Advantage: These are the preferred mounts for Non-M E36 owners looking to gain aggressive negative camber and increased caster for better front-end grip.
