Product Details

ICON's 4-5.5" Lift Stage 7 Coilover Conversion System features 2.5 Series CDCV remote reservoir coilovers that provide superb on-road comfort and off-road performance while at the same time allowing for end-user ride height adjustability. Their remote reservoirs greatly increase shock oil volume and heat dissipation surface area to resist overheating and cavitation under hard use, which can lead to damper fade. To take advantage of the coilover's option to mount secondary shocks in the stock location, 2.5 Aluminum Series CDCV remote reservoir secondary front shocks are included, effectively doubling shock damping ability on the front of the vehicle. ICON Vehicle Dynamics Ford Super Duty 4-Link kit further improves performance by eliminating suspension bind commonly experienced with factory radius arms during articulation and allows on-vehicle caster angle adjustment. This "œfreeing up" of the front end and the ability of the 4-Link Kit to maintain positive caster through the range of travel equates to an unparalleled ride quality in all conditions. The fabricated track bar drop bracket allows the axle to be properly centered under the frame and reduces road feedback throughout the steering system with improved on- and off-road manners thanks to the elimination of bump steer. An adjustable track bar allows for on-vehicle adjustment to fine tune track alignment as well as eliminating the deflective OE track bar bushings for an overall more rigid unit to improve the vehicles handling characteristics.

Night and Day Difference.
I only had one negative with my F-350 and that was the harshness of the ride. These shocks fixed my complaint and are amazing on the truck. Made it almost feel like an F-150 going down the highway. Highly recommend!

Really Great Shock For the 1st Gen Tacoma
These Icon Aluminum Series 2.0 w/ Reservoir shocks really impressed me. I paired these Icons with the Icon 3 leaf progressive AAL with my stock leaf pack, which gives me 1.5 inch lift in the rear. They have been an amazing upgrade from Bilstein 5100's. The quality of the machining and finish is great. And, the shipping was super fast from Shock Surplus.

Stage 2 4Runner Bliss
What a great lift and shock combination! Works very well on and off road. The further articulation of the billet UCA’s adds tremendous freedoms on the trail. And an excellent purchasing experience as their staff answers questions with knowledge and experience. Not the cheapest system, just one of the best!

The Expert's Opinion

"We've been big fans of Icon's total suspension approach since running the CDCV kit on our Tacoma back in 2017. Icon regularly provides the most travel in their shocks and suspension systems when compared to competitors, giving more lift height, or more usable travel."
