Bolt Saver 3.1 is the Ultimate Rennfix Solution for the differential rear mount bushing.
This bushing, unlike Bolt Saver II, does not work with the oem bushing, but is
a complete replacement. The design is similar to Bolt Saver Plus but is bigger
and stronger because there is only one bushing that has to work by itself. It
is also designed to be whisper quiet while doing it's high stress job. This bushing
is a one piece bushing unlike Bolt Saver 3 and has twice the carbon fiber of Bolt Saver II.
All Bolt Saver bushing kits; and any differential bushing kit, work best with the Bolt Saver Claws!
(Replacement Bolt not included)
Bolt Saver 3.1 is the main rear mount bushing for the differential.
This bushing is designed for the BMW X3M and X4M. This bushing is recommended
for both stock and high horsepower applications and works with both stock and one piece
aftermarket driveshafts such as the awesome Full Torque Driveshaft that we offer.
Install with confidence and we put great care into the design of this Bolt Saver kit just
like all the others, and just like all the others we stand behind it with our signature; but
true slogan - "Research the rest, install the best!"
