The Icon K214523P 4.5" Stage 3 Performance Suspension System for your 2014-2018 Ram 2500 6.7L Diesel 4WD was designed with exceptional performance and ride quality in mind. This Stage 3 system includes Icon-engineered 4.5" dual rate coil springs, high-strength laser cut bracketry, billet bump stop spacers, fabricated rear coil spacers, and all hardware necessary for a complete install. Vehicle-specific Icon 2.5 Aluminum Series remote reservoir shocks help deliver balanced performance front to rear, while CDC (Compression Damping Control) Valve technology allows the user to adjust compression characteristics of the shocks with the turn of a knob. These features make this Stage 3 system a huge upgrade for 2014-2018 Ram 2500 4WD trucks that are not only used for daily driving and towing but spirited off-road driving as well.
This system includes multi-rate rear coil springs for a more compliant ride. The lighter initial rate of these performance rear coil springs helps the truck feel smoother and more controlled over washboard roads, small whoops, or similar terrain. The secondary rate allows the truck to maintain exceptional ride quality over larger obstacles, while at the same time retaining factory payload capacity (at a reduced ride height). These performance systems were specifically developed for the 3/4-ton truck enthusiast who enjoys aggressive off-road adventures and dOEs not tow or haul heavy loads.

Soft, comfortable and really nice.
Size: Full
This product is of really nice material. It's soft and comfortable, deep pockets and fits my bed perfectly. It's a great product, however, if you're looking for something for back support, this isn't it. It isn't for me anyway - there's no firmness to this topper at all but it is very comfortable.

COMFORTABLE AND WORTH THE MONEY

Excellent mattress topper. Its thick and paired with my matress provides a high end hotel feel. I have had it for a few months and it has not lost its shape and stays in place. Worth the money. You are definitely getting what you paid for.

Wow!!!
Size: King
I couldn’t be happier with this mattress cover—it completely transformed my sleep.
I had one of the best nights of sleep I’ve had in a long time—no tossing and turning, just pure comfort. It stays in place nicely and feels high-quality and well-made. Fluffy without the bulk.
If you’re looking to upgrade your sleep without buying a whole new mattress, this is absolutely worth it. Highly recommend!

Best sleep matress topper
Size: Queen
Ordered after running out of options to get a good night's rest. Placed Q sized mattress topper on a tempur pedic matress and 1st night slept like a baby on a cloud. Ever since then I have knocked out after sleeping and moved less at night. Restful sleep has blessed out house again. It feels like a hotel comfy mattress. Totally recommend.
