Steeda Autosports has once again taken the S550 Mustang to the next level of performance and comfort with their exclusive S550 Mustang Differential Bushing Insert System - Street to Full Race Combo Kit GT! This combo kit comes complete with Steeda's Urethane and Aluminum Differential Bushing Insert Systems. When Steeda's engineers sat down to design these kits, they had to come up with a way to increase performance without sacrificing an ounce of drivability using urethane bushings. Steeda's engineers then also took hardcore racers into mind when designing the kit which utilises aluminium bushings.
Unlike competitors' kits that will absolutely increase NVH (noise, vibration, harshness), take 3-4 hours to install, and forces you to permanently modify the rear IRS suspension with a sawzall, Steeda's does not! Steeda's kit installs in under 1 hour, adds little to no increase in NVH, is adjustable and can be easily removed - it simply doesn't get any better than this!
Both Steeda's urethane and aluminum bushing inserts aim to minimise pinion angle changes, increase traction, eliminate wheel hop and differential deflection.
Steeda's urethane bushing inserts are made to their exact specifications and durometers, the kit comes with 3 different bushing options - the red 'street' 80 durometer bushings, the black 'performance' 90 durometer bushings, and Steeda's in-house billet 6061 aluminum bushings 'race'. Both urethane bushing options will increase performance with no increase in NVH, a Steeda-exclusive. Steeda's race kit installs in under 1 hour, is adjustable and can be easily removed. Since NVH was not an issue when designing the aluminium inserts, Steeda's engineers aimed to maximise reduction in wheel hop and differential deflection.
Steeda's kit adds the strength and support the OEM bushings need to perform the way 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.
