Unlike nearly all other mounts and brackets from other manufacturers, we use EPDM for our bushings. This provides much more vibration resistance when compared to polyurethane. This material is also extremely resilient and is able to stretch and even develop small cracks without affecting its structural integrity. EPDM is much more expensive to produce, but it is a far superior bushing material.
Our metal inserts are physically pressed into our EPDM bushings. This allows the bushing material and the metal to have a perfect connection without any gap. Other manufacturers cut their material out to fit, leaving small tolerances where the metal can still vibrate. Our construction allows the EDPM to absorb the vibrations and allows the metal inserts to smoothly move with the EDPM.
