SFI vs Standard (non-SFI)

Before purchasing a vibration dampner Verify your dampner obides by the rules and regulations applicable to your specific race class. Many race classes require an SFI approved dampner for track use. We highly recommend SFI dampners for all applications. Standard (non-sfi) dampners are non-certified dampers and will not be permitted for many race classes. We recommend SFI dampners for all race applications and high reving engines.

Here at R&D we highly recommend BHJ. We push there products not only because we get very good discounts, but more so that we've had nothing but great success with there balancers. Everyday we use our BHJ machining blocks as a testament to their excellence. Remember, no matter how much power you make or how efficient your combo seems to be, it won't matter shit if your crank flys out the block! So do your engine a favor and give her a good balancer. ATI and Innovators West also make durable dampers as well. All of which we are authorized dealers for, so why wait? Order your new balancer today and rest assured that you have only the highest quality products available.
