Pulling & Tensioning
Strength, Stability, and Simplicity — No Air Required
--
Everything your pulling and tensioning fleet needs for predictable performance
and less downtime — without the complications.
Less Sway, More Control
Reduces roll and flex when pulling reels or running tensioners. Keeps trucks stable on uneven ground or shifting loads.
Stays Level Under Load
Maintains height and alignment under changing tension and payloads for safer, longer-lasting operation.
Zero Maintenance
No air lines, compressors, or adjustments — just bolt-on performance built for demanding field use.
Made in the USA
Engineered and built in the USA, backed by a lifetime guarantee, and trusted by fleets nationwide.
Support When You Need It. Strength When It Counts.
SMARTER SUSPENSION FOR PULLING & TENSIONING EQUIPMENT
Every pull puts stress on your suspension — from heavy reels and winches to the constant shifting force of tensioning systems. Factory springs weren’t built for that.
SuperSprings helper springs automatically adjust to changing weight and pulling force, keeping your chassis level, stable, and predictable. They engage only when needed, reducing sag and sway without affecting ride comfort when unladen.
No air lines. No adjustments. No maintenance. Just consistent, bolt-on performance that keeps your pulling and tensioning trucks working safely, efficiently, and without interruption.
Product Spotlight – Trailer SumoSprings
STABILITY THAT MOVES WITH THE LOAD
PERFECT FOR REEL TRAILERS, TENSIONING TRAILERS, AND LINE EQUIPMENT HAULERS

Trusted by fleets, contractors, and equipment manufacturers alike, Trailer SumoSprings help your trailers track straighter, ride smoother, and stay level — mile after mile, pull after pull.
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
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
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.
M. Huang
Designed for the Pull. Built for the Pressure.
Every pull and payout puts new forces on your trucks and trailers — shifting loads, uneven terrain, and constant vibration that punish factory suspension. Our systems are engineered to handle that stress with stability, consistency, and zero maintenance.
Reel Trailers & Equipment Haulers
Control sway and bounce while supporting heavy, shifting reel weights during transport and deployment.
Fleet Builds & Upfits
Standardize suspension performance across chassis and trailers to simplify builds, reduce downtime, and extend vehicle life.
Tensioning Trucks & Winch Rigs
Maintain proper ride height and control when pulling line under tension, even during full spool load or uneven payout.
Field-Ready Durability
Proven in the toughest conditions — heat, cold, mud, or gravel — with no air systems to fail and no adjustments to make.
Build It Right. Keep It Tensioned.
