2021 Coleman UT400 rear suspension upgrade.


Recommended Posts

I have a 2021 Coleman UT 400. The weight capacity of the rear cargo was only 330 pounds and it’s sags with just 100 pounds in the back. I’m wondering if anyone has any insight on upgrading the rear shocks, and/or springs to give it a better weight load capacity? I’m sure all the popular shock brands out there like Elka suspension do not carry them for these particular models so if anyone has ever ran into this issue and has any ideas on upgrading the shocks and I would greatly appreciate it. Thank you.

Have you adjusted the spring preload to max for starters?20220812_122946.thumb.jpg.bb1f22077904ff869ef02151fe32984e.jpg

Keep in mind the coilovers are not the only reason for the weight limit; vehicle weight balance, frame strength, and max tire load are also limiting factors for the max safe load.

I'm not aware of any upgraded coilovers available, but I'm sure you could find something and make it fit if you wanted. It's just a function of spring weight and length between the mounting points.
