Your recreational vehicle has been equipped with the MORryde AllTrek 4000™ Suspension System. The MORryde
system is located between the axles on your trailer, replacing the steel equalizer (see diagram below). This system
is uniquely engineered to work in concert with your steel leaf spring suspension to improve overall suspension
performance.
At the heart of your MORryde system are MORryde’s rubber springs that have been a mainstay in the recreational
vehicle market for over 50 years. This system has been rigorously tested and engineered specifically for your trailer
using the rubber springs’ ability to isolate and absorb road shock and increase your trailer’s overall dynamic axle travel.
The combination of the MORryde rubber equalizer working in concert with your trailer’s leaf springs will greatly enhance
your suspension system’s ability to deal with today’s rough roads. This means you will experience:
· Smoother, more comfortable towing with over 40% more rubber than the CRE3000 to absorb road shock
· 4" of suspension travel backed by a 3 year warranty

AFTERMARKET TRIPLE INSTALLATION INSTRUCTIONS
Step 1
Loosen all lug nuts. Using appropriately rated jacks, raise
the unit and support the frame with safety stands. Support
the axles with floor jacks and remove all wheels.
Step 2
On the curbside of the unit, use an 11/16" socket and 13/16"
wrench and remove the shackle links from the front leaf
spring, remove the shoulder bolt from the center leaf
spring, and then remove the shoulder bolt from the top of
the equalizer.

Step 3
Replace the equalizer with the AllTrek 4000™ using one
of the 3.4" long wet bolts (shoulder bolt with grease jerk)
included in the installation kit. The threaded end of the bolt
will face the inside of the trailer. Slide the Outer Torque
Cross Member (cross member with slots and ears) onto
the end of the bolt, then install the 7/16-20 Flange Locknut.
Reinstall the front shackle links and install a new Shackle
Link Assembly and loose Shackle Link along with the 7/16-
20 Flange Locknuts. Do not torque any of the nuts.
NOTE: Use a hammer to pound the wet bolts into the frame hangers. Use
a pipe or small diameter socket to fit over the grease zerk and pound the
bolt in place (it is important not to damage the grease zerk) or remove the
zerk, pound the bolt in place, and reinstall the zerk. Make sure the grease
exit hole in the shoulder of the bolt faces to the side for easy grease flow.
Step 4
Remove the floor jack from the front axle and use it to
support the rear axle. Then, remove the shackle links
from the rear equalizer, then remove the shoulder bolt.
Step 3
Step 5
Replace the stock equalizer with the AllTrek 4000™
using one of the 3.4" long wet bolts. The threaded end
of the bolt will face the inside of the trailer. Slide the
Inner Cross Member (cross member with holes) onto the
end of the bolt, then install the 7/16-20 Flange Locknut.
Reinstall the shackle links.
* Triple axle AllTrek 4000™ cannot be used with Correct Track.
* Triple axle AllTrek 4000™ cannot have items hanging down under the frame between the equalizer hangers.

AFTERMARKET TRIPLE INSTALLATION INSTRUCTIONS
Step 6
Starting at the front of the frame and moving rearward,
repeat steps 2-5 on the opposite side of the frame using
the mating cross member channels.
Step 7
Torque all the 7/16-20 Flange Locknuts on the wet bolts
and shackle links to 40 ft-lbs.
Step 8
Install Cross Member Braces outside each equalizer
hanger using Spacer Tubes, 5/16-18 x 3.5 Flange bolts, and
5/16-18 Flange Locknuts. Tighten the nuts down evenly
on each side of the hanger being sure not to tighten a nut
more than one full rotation more than the nut on the other
side of the hanger. Torque to 20 ft-lbs. with a 1/2" socket
and wrench.
Step 9
Line up the holes on both front cross member channels,
and insert (4) 3/8-16 x 1 Flange Bolts on each side,
utilizing the holes farthest from the center in both the
top and bottom rows. Install the 3/8-16 Flange Locknuts
but do not torque.
Step 10
Repeat Step 9 for the rear cross member channels.
Then, use a 9/16" socket and wrench and torque all the
3/8-16 Flange Locknuts to 40 ft-lbs.
Step 11
Using (2) 1/2-13 x 4 Hex Bolts and (2) 1/2-13 Serrated
Flange Nuts, attach the Outer Support Cross Member to
the front cross member on the curbside. The Serrated
Flange Nuts should be against the Outer Support
Cross Member. Then do the same thing with the Inner
Support Cross Member to the rear cross member on the
curbside.
Step 5
Step 12
Line up the holes on both Support Cross Member
channels, and insert (3) 3/8-16 x 1 Flange Bolts on each
side. Install the 3/8-16 Flange Locknuts but do not torque.

AFTERMARKET TRIPLE INSTALLATION INSTRUCTIONS
Step 13
Repeat Steps 11 and 12 for the roadside. Use a 3/4" socket
and wrench and torque the 1/2-13 x 4 Hex Bolts to 95 ft-lbs.
Then, use a 9/16" socket and wrench and torque the 3/8-16
Flange Locknuts to 40 ft-lbs.
Step 14
Bolt the Axle Torque Brackets tp the center axle. In the
case of an overslung axle, install the Axle Torque Brackets
as shown. In the case of an underslung axle, install the
Brackets with the Torque Arm mounting hole at the bottom
of the axle instead of the top. Only install the U-bolts for
now and do not tighten the 7/16-20 Flange Locknuts.
Step 12
Step 16
Reinstall all wheels, then remove the jacks and supports
from the frame and axles. Torque all lug nuts according to
manufacturer specifications.
Step 15
Using the 2.9" Long Wet Bolts and 7/16-20 Flange
Locknuts, bolt the Torque Arms between the Front Cross
Member and the Axle Torque Brackets. Torque the nuts to
40 ft-lbs using an 11/16" socket and 13/16" wrench.
U-Bolt Torque Pattern
Visual Aid
U-Bolts must be tightened and torqued
using a cross-pattern sequence.
Tighten #1 and #2 to partial torque,
then #3 and #4 to partial torque.
Using the same sequence, fully torque
the U-Bolt Nuts.
Tighten the 7/16-20 Flange
Locknuts on the U-bolts to
pull the Axle Torque Brackets
up to the axle, then rotate the
brackets and insert the 3/8-16 x
3.75 Hex Bolts through the back
of the brackets behind the axle
seat and hand tighten 3/8-16
Flange Locknuts onto the bolts.
Now torque the U-bolts to 40
ft-lbs; these must be tightened
using a cross-pattern sequence
(see diagram) being sure not to
tighten a nut more than one full
rotation more than any of the
other nuts. Now torque the 3/8-
16 Flange Locknuts to 40 ft-lbs
using a 9/16" socket and wrench.

RUBBER SPRING INSPECTION
Figure 1 shows a rubber spring in good condition. If the rubber is compressed like the one shown in Figure 2,
measure the oset between the Beam Arm and the Spring Carrier. If the oset is 5/16" or less, the spring has worn
out and needs to be replaced.
NOTE: It is normal to see rubber spring weather checking, which consists of small surface cracks in the rubber. It is
also common to see minor tearing or fretting of the rubber around the edges. These conditions do not require the
equalizer to be replaced.

* According to tire manufacturer specifications, proper tire pressure means inflating tires according to individual wheel
weights (as long as a wheel is not overloaded), not necessarily inflating to the maximum pressure as specified on the tire.
NOTE: If a problem occurs that is not addressed here, please give us a call at 574-293-1581 or send an email to
[email protected] for further service information.
