This Motor Mount Kit for the '14-'17 Chevy SS from SuperPro provides some vibration dampening like the original mounts but is also much more durable, giving you a comfortable ride while increasing vehicle performance. The original rubber motor mounts flex and wear out, slowing throttle response and possibly damaging other parts under your hood, but these polyurethane engine mounts will hold your engine in place much better than the originals.
The motor mounts hold the motor to the frame, stabilizing the drivetrain and protecting your engine from moving around when you mash the go pedal, but if you're running the original rubber motor mounts then part of that mount is made of rubber. Rubber mounts deflect and allow the engine to move which can throw off your drive train and affect throttle response when you accelerate.
If you really want to firm up the drivetrain you can find solid motor mounts, but those will make a daily drive almost unbearable because of excessive vibration transfer from the engine to the cabin. But what if there was an in-between option that increased stability while still dampening some vibration?
Performance and Comfort
SuperPro's Polyurethane Motor Mounts will give your Chevy SS a more responsive throttle but not rattle your bones like the race car roughness of solid metal mounts. If you enjoy taking off at every red light as you cruise around downtown Dallas then switching from rubber to polyurethane motor mounts will cut down on the wait between pedal and power.
Polyurethane is more durable than rubber and can withstand the heat and motor chemicals that degrades and cracks rubber mounts. SuperPro is so sure of the longevity of these mounts that they cover them with one of the most comprehensive lifetime warranties in the business (which Suspension.com handles in house) that includes racing and offroad applications.
