Shock Absorbers
Comfort, stability, steering &
braking control with top-of-
the-line shocks
So, we can match the perfect ones to customers’ needs, Henderson’s features two different brands of shock absorbers for trucks & cars, and a third (Koni FSD) for motorhomes.
Our R&D Department has tested them for different applications. All have proven effective and durable for different applications compared to others on the market.
1. Koni shocks
Koni Shock Absorbers give you comfort, stability, steering and braking control under all conditions. Designed specifically for suspension characteristics of heavy-duty trucks, they dramatically improve your vehicle’s ride.
Their precisely balanced damping forces ensure comfort and road holding under all conditions.
Koni’s perform better and wear longer because of their precision manufacturing, highest qua-
lity materials, special design engineering, and intensive testing program.
After many thousands of miles, when other shocks would be completely worn out, these shocks finally start to show wear.
Perform Like New Again With
Simple Adjustment
Simple Adjustment
You restore damping forces on the Koni by simply adjusting them. Each Koni Heavy Duty shock features in excess of 100% reserve damping forces.
Koni truck shocks can be adjusted up to 5 times to perform like new again.
Koni’s have adjustable rebound built in. Their leaf spring suspension features two leaves that actually rub against each other to create friction, which keeps it from bouncing. With the air bags, it’s just like a basketball. When you compress it, it bounces back.
Henderson’s Personal Touch When Henderson’s installs Koni shocks, we set the rebound setting to take care of this problem. You get restored ride and better handling.
Koni uses the finest materials available, machined to aircraft tolerances. They dynamometer test every shock, to assure 100% quality control. You get a lifetime guarantee with each shock absorber.
These shocks cost a little more than other brands initially but they have proven less expensive over the long haul.
Heavy-Duty Features
Koni shocks boast features you won’t find in other brands.
Their special viton seals are critical for long life. They machine the piston rod guide from solid stock. Precise orifices in the piston rod regulate oil flow. Piston rods are precision ground from hardened solid steel for the greatest strength possible, then hard-chromed for durability.
The inner cylinder is thick walled, precision drawn seamless steel. The piston valve is made of hardened steel for longer life. The bypass valve regulates oil distribution and guarantees optimum damping. The adjusting nut controls reserve damping forces. The foot valve is made of more than 10 precision parts, valves, and springs to regulate accurate oil flow during compression.
2. Bilstein Shocks
These Gas Pressure Shock Absorbers per-
form well on most SUV’s, pick ups and passenger cars.
With nearly a half century of gas pressure shock absorber expertise, Bilstein is recognized as a leader in design, quality, and reliability. Over the years, their patented mono-tube, high gas pressure design has been proven to give long life performance.
Bilsteins outperform conventional shock absorb-
ers 4 to 1. They operate at 98% efficiency for more than 100,000 miles.
Bilstein uses only the finest quality components and hand-assembles them. More than 40% of their production personnel are involved in quality control to assure you get top quality in the final product.
Warranted As Long As
You Own Your Vehicle
You Own Your Vehicle
Bilstein is so confident of the reliability of their shocks they warrant them for as long as you own your vehicle.
Plus Henderson’s Own Guarantee At Henderson’s, we back Bilstein’s warranty with our own guarantee on parts and labor.
If you’ve had new shocks installed on your motorhome and it still doesn’t ride smoothly, the problem may not be the quality of shocks. Putting the wrong shock absorbers on a motorhome is a common mistake.
