hear the "thud", your rear diff mount's a dud!
Our heavy duty rear differential mount is the best
upgrade for your current worn unit. The original mount in this
particular location wears prematurely and can cause a heavy "thud"
during shifting and spontaneous throttle inputs. It's open hydro
fluid filled design does a great job of reducing NVH, but can have
a service life of less than 60K miles on performance driven cars.
Our heavy duty unit is made of solid robber for a stiffer feel
while retaining the safety and comfort of the stock mount. The E46
non-M cars have 3 differential mounts - 2 front mounts and 1 rear.
This heavy duty mount is the rear location which is the typical
failure part. We also have the front rubber mounts available. Four
year warranty included with all HD products.
1 rear mount is needed per car.
*M3 and MZ4 have a redesigned rear differential
cover with dual mounts for added strength.
