Product Reviews for 2015-17 Mustang GT Steeda Adjustable Differential Bushing Insert System - Urethane 555-4439
Steeda Autosports has once again taken the S550 Mustang to the next
level of performance and comfort with the exclusive 2015 Mustang GT
Steeda Adjustable Differential Bushing Insert System - Urethane
555-4439! When engineers sat down to design this kit, they
had to come up with a way to increase performance without sacrificing
an ounce of drivability all while keeping the car quiet!
Unlike the 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 around 1 hour, adds ZERO increase in
NVH, is adjustable and can be easily removed - it simply doesn’t get
any better than this!
Minimize 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,
the kit comes with 2 different bushing options - red 'street'
80 durometer bushings and black 'performance' 90 durometer
bushings. Both bushing options will increase performance with no
increase in NVH, a Steeda-exclusive.
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
around 1 hour. Bushings are included for both the front and
rear differential mounting locations. Grade 10.9 hardware is included
with zinc-plated washers. Note: For hardcore
enthusiasts that want ZERO pinion deflection, try the 555-4440
kit. This kit features aluminum bushing inserts. For race-use only as
it will increase NVH and gear noise. Product Benefits
