MORryde UO12-016 heavy duty shackle kit is the tandem-axle suspension hardware upgrade for RV trailers using 2-1/4" (2.25") shackles, including SRE4000, CRE3000, and compatible stock suspension setups. It replaces light-duty or worn suspension hardware with thicker shackles, bronze bushings, greasable wet bolts, and Loctite nuts so the running gear stays serviceable instead of wearing dry.

Why Choose This MORryde UO12-016 Kit?
Worn shackles and dry bushings can lead to clunks, uneven suspension movement, elongated brackets, and rougher towing. This MORryde kit is built for owners and technicians who want a maintainable suspension setup instead of reinstalling light-duty hardware that may wear again quickly.
The key fitment limit is axle count, hanger style, and shackle length. UO12-016 is the tandem-axle, standard-hanger kit for 2-1/4" shackles. If your trailer has Correct Track hangers, triple axles, or 3-1/8" shackles, use the matching MORryde kit instead of forcing this one.

Frequently Asked Questions
How do I know if MORryde UO12-016 is the right shackle kit?
Confirm your trailer is tandem axle, uses standard hangers, and has 2-1/4" shackles. The MORryde chart on this page identifies UO12-016 for SRE4000, CRE3000, and compatible stock setups with 2-1/4" shackles.
Is this a repair part or an upgrade?
It is both. UO12-016 replaces worn or light-duty suspension hardware while upgrading the trailer to thicker shackles and greasable hardware for easier maintenance.
Does this fit Correct Track hangers?
No. This is the standard-hanger UO12-016 kit. Tandem-axle trailers with Correct Track hangers should use the matching Correct Track kit, such as UO12-029 when the rest of the fitment matches.
Does this fit triple-axle RV trailers?
No. UO12-016 is for tandem-axle applications. Triple-axle trailers require a triple-axle MORryde shackle kit.
What should I inspect while installing this kit?
Check the equalizers, brackets, bushings, bolts, and hanger condition while the suspension is apart. Replace only with compatible MORryde or verified RV suspension components.
