Restore crisp handling response and eliminate dangerous steering column slop with the ATRO MS59-69014 Premium Polyurethane Steering Shaft Isolator. Proudly Made in the USA, this heavy-duty, commercial-grade underhood component is specifically engineered as a direct replacement upgrade for failing factory steering column isolators on Kenworth class 8 trucks.
The steering shaft isolator plays a vital role in your truck's steering linkage: it dampens punishing road vibrations and engine chassis harmonics before they reach the steering wheel, while maintaining a rigid, positive connection for driver control. Traditional OEM isolators are manufactured from standard rubber compounds that quickly break down under the hood. Constant exposure to extreme engine heat, turbo radiation, engine oils, and road salts causes the rubber to soften, tear, or take a permanent compressed set. This breakdown results in excessive "dead zone" play in the steering wheel, wander on the highway, and driver fatigue.
ATRO’s proprietary high-durometer polyurethane chemistry is chemically immune to underhood fluids and engine thermal cycling. It absorbs grueling torsional impacts without tearing or deforming, ensuring your steering assembly stays tight, safe, and true for the long haul.
Premium Polyurethane Material: Outlasts traditional OEM rubber variants by resisting thermal heat cracking, ozone rot, oil saturation, and high-load tearing.
Eliminates Steering Wheel Play: Maintains strict structural rigidity to ensure immediate steering response and eliminate loose wandering on the highway.
Chemical & Oil Immune: 100% resistant to degradation from power steering fluid, engine oil, diesel fuel, and winter road de-icers.
Proudly Made in the USA: Manufactured in the United States to strict commercial vocational standards for dependable, long-haul fleet reliability.
