When our engineers sat down to design this kit, we had to come up with a way to increase performance without sacrificing an ounce of drivability all while keeping the car quiet!\u003c\/p\u003e\n \u003cp\u003eUnlike our competitors' kits that will absolutely increase NVH (noise, vibration, harshness), take 3-4 hours to install and force you to permanently modify the rear IRS suspension with a sawzall, Steeda's does not! Steeda's kit installs in under 1 hour, adds \u003cstrong\u003eZERO increase in NVH\u003c\/strong\u003e, is adjustable and can be easily removed - it simply doesn't get any better than this!\u003c\/p\u003e\n \u003cp\u003eMinimize pinion angle changes, increase traction, eliminate wheel hop and differential deflection with Steeda's new kit. Made from high-strength urethane to Steeda's exact specifications and durometers, our kit comes with 2 different bushing options - our red street 80 durometer bushings and our black 'performance' 90 durometer bushings. Both bushing options will increase performance with no increase in NVH, a Steeda-exclusive.\u003c\/p\u003e\n \u003cp\u003eSteeda's kit adds the strength and support the OEM bushings need to perform the way our customers intended. Once again, this is not a permanent modification - there is no drilling, cutting or pressing required. Simply loosen and remove a couple bolts and this kit installs in less than 1 hour. Bushings are included for both the front and rear differential mounting locations. Grade 10.9 hardware is included with zinc-plated washers.\u003c\/p\u003e\n \u003cp\u003e\u003cstrong\u003eNote: \u003c\/strong\u003eFor hardcore enthusiasts that want ZERO pinion deflection, try our 555-4440 kit.
