“Big Rig” shock absorbing power — RoadKing® motorhome shocks
New on the market – the RoadKing® big-bore mono-
tube motorhome shock may be the best in the world –
- Cuts coach ride harshness
dramatically as it corrects motorhome suspension. - Gives your vehicle more
stability & control than
any conventional motor-
home shock on the market.
Up to 350,000 miles service
RoadKing® performs like new up to 350,000 miles. Expect to increase tire mileage, reduce cupping and lower tire temperatures up to 30%.
Designed for Big Rigs
This shock was originally designed to counteract the pounding drivers take as they drive heavy-duty Kenworth, Peterbilt and Freightliner class 8 trucks. Professional truck drivers say RoadKing®s deliver more ride comfort and control on their big rigs.

Body of the shock engineered steel-clad plated & corrosion-free for long-wear.

Why RoadKing®delivers better and longer-lasting performance than any standard shock on the market
hydraulic piston bore
Conventional small bore motor home shocks need higher damp-
ing forces at low shaft speeds to generate control for heavy vehi-
cles. Lack of damping force means ride harshness on potholes & rough highway. RoadKing® employs a totally different force adjustment range than small bore, light truck shock absorbers motorhomes currently use.
You drive with more comfort & less fatigue because RoadKing®’s damping control slows down all roll, pitch, bounce, yaw and overshoot. You arrive more refreshed because you’re no longer forced to focus so hard on steering your rig.
Your coach holds the road much better than conventional shocks because you gain tire & axle control. Tires bounce like hard basketballs when they hit a pothole, tar strip or rough highway surface. RoadKing® stops the bouncing and keeps tires connected to road surface. They eliminate ride harshness.
“This big coach drives better than my car” …says John Rudkins of Springfield, Oregon. “The Workhorse chassis has never felt so good driving as it does now. The big coach drives better than my car. I’m very happy with the new RoadKing® shocks on my 2003 Dolphin Motorhome.”

Delivers far more than its price
As you might expect, at $425 per unit plus installation, RoadKing®s are more expensive than conventional motorhome shocks because they cost more to produce and install. However, since they last up to seven times longer, perform radically better than any ordinary shock — and do that job for life — we think you’ll agree their performance justifies the price.
