Please Note: When placing your order for this kit, there are 3 different rear mount styles ( the rear mount bolts to the rear subframe behind the engine). One is a tall style mount with a 4 hole bolt pattern. The second a short style mount with a 3 hole bolt pattern (sits flat on the rear subframe). Finally the third mount (more common on the auto chassis) is a tall 3 bolt mount & has a vacuum assist solenoid attached to it. If you are unsure which style you need feel free to contact us before ordering. (626) 261-4052
Factory mounts are usually made of thin gauge metal stamped and partially inserted with a rubber material. The rubber usually has two or more sections that meet in the center to hold the center pin. These sections do not hold the motor firmly and are prone to break under sever driving conditions and/or when used in performance applications.
Innovative Mounts has engineered a unique polyurethane bushing unlike no other. Their bushings are solid, will never wear or break, and come with a life time unconditional warranty. A key design decision in Innovative bushings is that it makes minimal physical contact with the mounting bracket or chassis. The shape of the urethane bushing is tapered to prevent binding between the chassis and/or mounting bracket. This allows the urethane to gradually absorb engine movement and vibration.
All of Innovative bushings are designed in the same general shape. What varies next is the hardness or durometer rating of the urethane.
60A Red - The 60A Red bushings are recommended for street cars. Most of our kits come standard with these bushings. They provide the least amout of vibration transfered from the engine to the chasis. This equates to a more comfortable everyday ride.
75A Black - The 75A Black bushings come standard on all H/F - Series engines. These engines weigh more and need a stronger bushing. We recommend 75A for street and track vehicles that make more than average horsepower. This rating of bushing is also for those that would like a stiffer feel and less engine flex.
85A Grey - The 85A Grey bushings is designed specifically for race cars or drivers that seek a solid engine mount kit.
95A Red - The 95A Red Extreme pretty much race only... Figure these bushings are 95 out 100% solid.
