MORryde SRE 4000 vs ALLTREK 4000 RV Suspension Parts Comparison & Returns

If the delivered suspension differs from your order, compare the ordered part number with the label on the delivered kit and contact Elkhart RV Parts with the order details and clear label/package photos before installation. This published question does not establish what was shipped or authorize a return, credit, exchange or replacement.

SRE4000 and ALLTREK 4000 are distinct product families; the family names alone do not prove either interchangeability or incompatibility for your trailer. MORryde’s 2021 catalog identifies SRE3-733X as a 33-inch-wheelbase triple-axle kit and SRE3-735X as a 35-inch-wheelbase triple-axle kit, and describes the SRE4000 system with an X-Factor crossmember. That historical catalog does not establish current supply or the contents of a particular delivered package.

MORryde’s current ALLTREK product page describes its tandem kit as two equalizers and says no crossmember is required. Use the exact kit’s current qualification instructions and manufacturer confirmation for axle count, wheelbase, hanger geometry, clearances and existing equipment. Do not select a replacement from the shared “4000” name.

For an individual SRE service equalizer, identify the installed assembly and obtain its exact service part number and current availability from MORryde before ordering. An existing crossmember’s condition alone does not establish that a service part fits or that the crossmember can be reused. The two listings below retain native SRE part numbers. Their descriptions distinguish those identities from ALLTREK part numbers; treat them as identification references rather than confirmation of a supplied kit or approved successor.
