It appears you will need the MORryde Suspension Upgrade Kit # MR46ZR for your 2021 Grand Design Reflection 303RLS. These shackles measure 2-1/4" from center of shackle hole to center of shackle hole. We also have the 3-1/8" Kit # MR76ZR if you have the longer length shackles.

I recommend filling the wet bolts with Grease # L11390 using the Grease Gun # L30416. The flexible hose and pistol grip handle make it easier to reach all the bolts.

We do carry the Lippert Electric Trailer Brake Assemblies Left #LC96WD and Right #LC46WD from Lippert for their 4,400lb axles. These brakes are self-adjusting like the Electric Trailer Brake Kit #AKEBRK-35-SA.

In order to determine the torque rating for the lug nuts on your trailer you will need to know check out the chart I attached that shows all of the torque specs for all the trailer lugs available based on stud size, wheel material and wheel size.

The difference between an load range C and load range D tire in the same size is the capacity and psi rating. The two tires will still have the same dimensions and fit on the same wheel. The D rated tire has a higher capacity. For a ST175/80D13 like…

Load range B trailer tires are going to have a lower capacity than C load range tires. Basically that, psi rating, and the ply rating are the only differences. A higher load range tire would last a little longer than lower load ranges of the same…

To find the load capacity for your axle you should look on the trailer VIN plate or sticker that lists the VIN number. The weight rating of the axle should be listed on that same plate or sticker. Also, the axle could have a tag or plate on it that…

Answer 7

I contacted MORryde and this does happen from time to time as the weight of the trailer can spread out the axles due to downward pressure on the springs/suspension. Odds are the 35" wheel base #MR27ZR will be the correct one for you, but they…

Answer 9

The spring hanger placement is going to be determined by your axle spacing. For example, if your axles are spaced 33 inches apart, as shown in the attached diagram, a 7K axle slipper spring, like #e74SR, requires a distance of 28-1/2 inches between…

Answer 10

Your math is correct in your trailer weight load example. If a fully-loaded tandem axle trailer weighs 4000-lbs then each of the 4 tires will bear 1/4th of that load, or 1000-lbs. In this case a tire rated for 1300-lbs would provide a good safety…

Answer 11

I attached a picture that shows the proper position of shackles and equalizers on trailer suspension. Sometimes the shackle will flip up but if you jack up the trailer by the axle that's got the shackle flipped you can usually get it to flip back…

Answer 12

Yes, axle spread and wheel base by definition are the same measurements. You will measure from the center of one axle to the center of the 2nd axle to determine what you axle spread is. This may be difficult as some wheels and covers will make this…
