JXB Performance Driveshaft Carrier - Evo X Front and Rear - Track Bushings - DSM04A1-T
The stock center support bearing carriers hold the driveshaft in place with
a layer of thin rubber. While that’s great for making sure no NVH makes it
to the cabin, it doesn’t keep the bearings centered well under load, allows
the bearings to sag and ruin driveshaft alignment over time, and creates
slop in the driveline during shifts and throttle application.
Over time the OEM bushings become brittle, eventually dry rotting and
cracking. Even on the best-kept cars, the stock bushings can start to form
cracks in as little as 5-10 years.
When the bushings wear and sag, it changes the alignment of the driveshaft,
putting more stress on the joints. During rapid loading of the driveshaft
(launches, shifts, and quick application of the throttle), the bearings are
allowed to travel off-center, introducing slack in the driveline, which
results in laggy and unpredictable driveline response.
Our upgraded driveshaft carriers keep the driveshaft firmly in place at all
times. The more solid bushings ensure the bearing cannot move from center,
maintaining torque delivery and driveshaft alignment at all times,
resulting in more direct driveline response under all conditions.
Benefits as described by our customers include:
More direct throttle response
Firmer, more direct shifts
More instantaneous launches
Reduction in vibration due to driveshaft misalignment and/or rubber
deterioration
Smoother low-speed on/off throttle behavior (1st gear in parking lots)
The videos below show how OEM driveshaft carriers react to driveshaft loads
and the improvement with our carriers.
Installation doesn’t require removal of the driveshaft. The 2-part design
clamps around the OEM bearing. The old carrier must be removed, so a
cutting tool is required.
The exact steps to access the carrier will vary slightly by model, but the
removal and installation of the new carrier are the same. The basic steps
are:
Remove any braces or splash shields preventing exhaust and heat shield
removal
Remove or lower exhaust in area of center support bearing if needed for
access
Remove heat shielding covering center support bearing
Cut off OEM carrier and remove rubber support material with razorblade,
leaving base layer of molded-on
rubber intact on the bearing
Clamp new carrier around OEM bearing

Street and Track refer to the durometer (stiffness) of the bushings. Track
are roughly twice the durometer of the street bushings. Both track and
street are many times stiffer than stock and will hold up to whatever abuse
are thrown at them, but the street bushings are better at soaking up
drivetrain noise and vibration. Usually both street and track are
completely silent and vibration-free, but in cases where there is an
underlying drivetrain issue causing the driveshaft to vibrate badly, the
track bushings may not be able to soak it all up, where the street bushings
can.
We generally recommend street bushings for any car that's not purpose-built
for track or overland use, since the street bushings have a much lower
chance of transmitting drivetrain NVH to the cabin at high speeds or under
heavy throttle loads.
If you’re not sure which to go with, the “Give me Both!” option will give
you a full set of each of the street and track bushings. You can use all
street, all track, or even mix and match them to find the perfect balance
of performance and NVH-absorption.
