MORryde - PT108-020 #20 PT Rubber Shear Spring - LRE/RS/SRS Systems

The MORryde PT108-020 #20 rubber shear spring is a replacement spring for MORryde rubber suspension systems when the original spring is worn, torn beyond MORryde’s service limit, or needs to be matched by the stamped spring number. This is the #20-density PT-series spring, so match the part number and the number stamped into your existing rubber block before ordering.

Use this part for MORryde LRE, RS, and SRS-style rubber suspension service where PT108-020 is the correct replacement. It is not a universal trailer spring, a complete axle, or a substitute for confirming your system’s GAWR, axle count, and original spring marking.

Why Choose the MORryde PT108-020 Rubber Shear Spring?

Rubber shear springs help the MORryde suspension absorb road shock and protect the trailer from the harshness of conventional leaf-spring-only movement. Replacing the correct spring restores the suspension system without guessing at a different density or unrelated rubber block.

The key is matching the existing spring. MORryde rubber springs are selected by the stamped number on the rubber block, the unit’s axle weight rating, and whether the trailer uses a tandem or triple axle setup. If your current spring is stamped 20 and your system calls for PT108-020, this listing gives you the exact part-number match.

Frequently Asked Questions

How do I know if PT108-020 is the right MORryde rubber shear spring?

Start by checking the number stamped or embossed on your existing rubber block. PT108-020 corresponds to the #20 PT spring. Also confirm your MORryde suspension system and axle setup before ordering.

When should a MORryde rubber shear spring be replaced?

MORryde says small surface cracks and weather-checking are normal. Replacement is recommended when a tear reaches at least 3" long by 3/4" deep, because that can affect the spring rate.

Is this a complete torsion axle replacement?

No. This is a rubber shear spring used in compatible MORryde suspension systems. It is not a complete axle assembly and should not be used as a universal replacement without confirming the system requirements.

Should I replace both sides at the same time?

For balanced suspension service, many installations replace matching springs on both sides of the unit at the same time. Confirm the quantity needed for your specific MORryde setup before ordering.

Does the spring density matter?

Yes. MORryde uses different rubber spring densities for different applications. The GAWR, axle count, and stamped number on the original spring all matter when selecting the correct replacement.
