BUCKET TRUCKS

Job sites are rarely smooth — uneven pavement, gravel, and off-camber terrain push factory suspensions past their limits under constant boom, outrigger, and tool weight. SumoSprings provide progressive, airless performance built for real-world work, delivering consistent stability, less sway, and a level ride from the yard to the site and back — with no air lines, compressors, or maintenance.

Built for the Work, Not the Workshop
--

Everything your bucket trucks need for stable, reliable performance —
without the maintenance.

Progressive Load Support

Absorbs vibration and impact from uneven worksites while maintaining predictable handling under heavy or offset loads.

Unrestricted Operation

SumoSprings and SuperSprings function seamlessly with outrigger systems and boom setups, maintaining full articulation without interference.

Zero Maintenance

No air lines, compressors, or recalibration — just consistent performance that keeps trucks in service and out of the shop.

All-Weather Reliability

Engineered to perform year-round — through heat, cold, mud, snow, and jobsite grime — with no loss in strength or stability.

Strength You Can Count On, Shift After Shift

SMARTER SUSPENSION, FEWER WEAK POINTS

Bucket trucks work under constant load — booms, outriggers, and tool systems that challenge even the toughest chassis. SumoSprings Solo and Rebel use microcellular polyurethane that compresses progressively as load increases, providing soft engagement on small bumps and firm control under heavy weight.

You get smoother rebounds, reduced sway, and a level stance that keeps your operators confident and your fleet productive — with no air systems to service, no leaks, and no downtime.

Product Spotlight – SumoSprings Rebel

BUILT TO WITHSTAND THE WORK

Perfect for Bucket & Aerial Trucks
The SumoSprings Rebel is purpose-built for heavy-duty vehicles like bucket and aerial trucks that carry constant, elevated loads. Its two-piece, airless design separates at full droop for unrestricted articulation, then re-engages under compression to deliver smooth, progressive support.

The result is a suspension system that stays level, stable, and predictable under the weight of booms, outriggers, and service bodies — all without air lines, compressors, or ongoing maintenance. Trusted by OEMs and upfitters across North America, the Rebel helps fleets reduce downtime, improve operator comfort, and extend vehicle life — one install at a time.

What Our Customers Are Saying

My 2017 Hyundai SF is a great SUV with the only complaint I’ve had is the rear suspension seems underside and appears to easily bottom out. I had the Coil SumoSprings installed and they made a noticeable improvement when pulling a 21′ boat.

Scott

2017 Hyundai Santa Fe

I just did a 900-mile ski trip from South Carolina to West Virginia in my 2017 Dodge Journey. With the car packed to the roof and skis on the rack, the rear Coil SumoSprings made a huge difference — cutting down sag, improving stability, and reducing body roll on curvy mountain roads. Install took some effort, but it was worth it. I’ve already ordered the front set to complete the setup.

Clarkson

2017 Dodge Journey

Bought a pair of the CSS-1195 for my 2018 Toyota Sienna XLS AWD. Very easy to install the SumoSpring for the front suspension. Noticeable improvements of the body roll reduction at the corners, which leads to better handlings and driving experience. Very satisfied with the purchase.
