Mounting the subframe and the body is a vehicle's subframe bushings. Normally, OEM subframe bushings are made of soft rubber and, over time, this soft rubber begins to wear and crack. The subframe bushings main responsibility, besides mounting, is to dampen road noise and vibration from entering the cab. So once these bushings fail, you'll feel an increase in noise and vibration into the cab of your vehicle.
Whiteline's subframe bushings are made of synthetic elastomer, much more durable material for subframe bushings. With synthetic elastomer subframe bushings, you'll see a faster launch time by effectively eliminating wheel hop. Not only do you get a performance boost with synthetic elastomer, but you have it for a long time. Synthetic elastomer bushings do not distort or crack like OEM rubber. Whiteline covers their subframe bushings with a lifetime warranty that can be handled through our customer service team at DST. A slight increase in NVH should be expected due to the firmer material, but the performance and longevity benefits make Whiteline's synthetic elastomer bushings worth it.
