Radflo 500R Sport 2.0 Rear IFP Shocks (Pair) for 1999-2006 Toyota Tundra
Upgrade the rear suspension of your first-generation Toyota Tundra with a pair of Radflo 500R Sport 2.0 Rear Internal Floating Piston (IFP) Shocks. Designed for trucks running factory ride height or up to 2 inches of lift, these shocks provide improved ride quality, better vehicle control, and increased durability over factory shocks.
The Radflo 500R Sport Series is built for owners looking for premium performance without stepping into a remote reservoir shock. Utilizing Radflo's race-proven monotube design, high-flow FreeFlo piston, and Internal Floating Piston (IFP) technology, these shocks deliver consistent damping and excellent ride quality whether you're commuting, towing, exploring backroads, or spending weekends off-road.
Unlike standard replacement shocks, the 500R Sport Series is fully rebuildable and revalvable, allowing your suspension to evolve as your truck does. Built in the USA using premium materials, these shocks are engineered to provide years of dependable performance while remaining serviceable for the life of the vehicle.
Sold as a matched pair, these shocks are ready to bolt onto your Toyota Tundra and provide improved comfort, increased stability, and greater confidence both on and off the pavement.

FAQ
Why choose the 500R Sport Series?
The 500R Sport Series offers a significant improvement over factory shocks by combining monotube performance, IFP technology, rebuildable construction, and premium ride quality in a direct bolt-on package.
What is an Internal Floating Piston (IFP)?
The Internal Floating Piston separates the nitrogen charge from the shock oil, providing more consistent damping, improved ride quality, and reduced shock fade under demanding conditions.
Can these shocks be rebuilt?
Yes. Like all Radflo performance shocks, the 500R Sport Series is fully rebuildable and can be serviced or revalved in the future.

Yes. These shocks are designed for factory ride height and vehicles with up to 2 inches of lift.
