KYB Suspension Shock Absorber P/N:3440137
Add heavy-duty control to your work truck with the KYB MonoMax Shock Absorber (MPN 565133), a KYB shock absorber engineered for vehicles that do real work, go off-road, tow a trailer or haul heavy loads. This rear shock drops in as a direct-fit replacement for the 2007-2021 Toyota Tundra.
The large-bore KYB MonoMax is a heavy-duty monotube design that helps deliver the added stability heavier, more powerful, or high-center-of-gravity vehicles demand, adjusting to driving conditions with fade-free performance.
Worn shocks can show up as excessive bounce, nose-dive under braking, or poor load control; if the original rear shock is the cause, this replaces it.
