Tough conditions demand tough truck shocks. The large bore KYB MonoMax provides the additional stability that heavier, more powerful or high center of gravity vehicles demand. The KYB MonoMax is a heavy duty monotube shock absorber that provides the most handling, control and durability of any KYB shock; and its just for trucks. The MonoMaxs tough design automatically adjusts to driving conditions with fade-free performance. The KYB MonoMax has an outstanding reputation for vehicles that do real work, go off-road, tow a trailer or haul heavy loads. It uses a work-ready, zinc-coated steel piston ring and includes an off-road dust boot.
Characteristics include:
Maximum performance upgrade with up to 40% more damping performance than standard shock absorbers
Perfect solution when you need to upgrade the suspension performance on your GM truck
Truck monotube design outperforms all other standard shock absorbers
Zinc-coated, stainless steel piston ring provides a positive seal in the most extreme conditions
Rubber boot to protect the shaft and keep dirt and debris away from the seals
Engineered to help vehicles with electronic safety systems (ESC, ABS, etc.)
