E39 SEDAN BMW SUBFRAME BUSHINGS POLY FILL - 33311091422 Upgrade the subframe bushings in your E39 with the Garagistic E39 BMW Poly Fill Subframe Bushings ( 33311091422 ). These bushings provide increased stiffness and performance with OEM fitment. We take a set of factory E39 subframe bushings and fill all the air pockets with 80A polyurethane. This increases the bushings density, further insulates the center race (metal center sleeve) and stiffens the entire bushing. By poly-filling these bushings, we provide an OEM ( 33311091422 ) fit bushing with the performance benefits of a polyurethane bushing, the best of both worlds. The E39 subframe is the base for the entire rear suspension of the car including the differential. By stiffening the bushings used to mount the subframe your car will have a more solid base for the suspension allowing everything to move in a more predictable manner. Get the maximum performance out of your E39 with the Garagistic Poly fill subframe bushings. Save yo
