Anodized Aluminum Body
Internal or Remote Reservoir
Quiet and Corrosion Resistant
Features
- Anodized Aluminum Body: The shock body and reservoir tubes are anodized 6063 aluminum, which sheds heat well and holds up against corrosion. The rod end, top cap and internal parts are machined 6061 aluminum.
- Valving for Your Vehicle: A one-piece linear/digressive piston carries valving chosen for the vehicle and its lift range, so the body stays settled on pavement while bumps on the trail get soaked up.
- Internal or Remote Reservoir: Internal reservoir versions keep the nitrogen charge inside the shock body. Remote reservoir versions move extra oil into a separate canister on a hose, adding cooling that helps hold off fade on long rough runs.
- Fits the Factory Mounts: Polyurethane bushings, zinc-plated sleeves and forged steel mounting stems let each shock go into the vehicle's original shock mounts.
- Quiet and Corrosion Resistant: The hardened steel shaft is chrome plated to resist pitting and rust, and a nitrile rubber top-out bumper keeps things quiet when the suspension reaches full extension.
- Rebuildable and Revalveable: Every 2.0 Series shock can be fully serviced. It can be rebuilt when it wears, or revalved if the load or the way the vehicle is used changes.
Description & Fitment
The ICON 2.0 Series shock absorber is a rear shock for the 2005-2023 Toyota Tacoma 4WD with a 0-1.5" lift. It comes in non-reservoir or remote reservoir versions, and the remote reservoir adds oil volume and cooling area to keep damping consistent when the shock gets hot. The body and reservoir tubing are anodized 6063 aluminum, and the valving is tuned for the vehicle. It can be rebuilt and revalved later, and install includes drilling, cutting or trimming steps.

About ICON Vehicle Dynamics
ICON Vehicle Dynamics designs and builds performance suspension for trucks and SUVs at its shop in Riverside, California. Engineering is led by Dylan Evans, its head engineer and a SCORE champion driver, and ICON tests its parts on the street, on the trail and under race conditions.
ICON's engineers begin with the result they want from a vehicle, then study the forces acting on it in motion, which is where the name Vehicle Dynamics comes from. Fabrication stays in ICON's own shop, from laser cutting and metal forming to CNC machining, welding and final assembly. ICON calls its suspension systems and shock absorbers the top choice for popular trucks and SUVs.

Frequently Asked Questions
Will this fit my 2005-2023 Toyota Tacoma?
It fits when your vehicle matches one of these rows: 2005-2023 Toyota Tacoma (4WD; 0-1.5" lift). If you are unsure about your trim or drivetrain, send us your VIN and we will check it against ICON's application list before you order.
Does the install involve cutting or drilling?
Yes, ICON's install sheet for 56503 includes drilling, cutting or trimming. Read the sheet in the Installation section below before you start, or have a shop do the work.
Do I need to order two shocks?
Yes, for one axle. Most 2.0 Series part numbers are a single shock, and ICON calls for two per axle. Some remote reservoir parts are made for one side, so order the driver side and passenger side numbers together.
Internal or remote reservoir: which should I pick?
An internal reservoir shock is the simpler install, with nothing extra to mount. A remote reservoir shock carries more oil and more cooling surface, so it resists fade better on long rough drives, and it needs its reservoir bracket mounted near the shock.
Should I choose the 2.0 or the 2.5 Series?
ICON aims the 2.0 Series at daily driving and weekend trail use. For extreme off-road driving it points owners to the 2.5 Series, which is stronger and handles heat better.
How often do ICON shocks need service?
ICON's maintenance guide suggests a factory service about every 40,000 miles for street use, or about every 15,000 miles for a mix of street and dirt, and sooner if a shock leaks, rides worse or gets noisy. Wash off salt and mud, wax the bodies once a year and check the nitrogen charge yearly.
Installation

- Locking Pliers
- 17mm Socket / Wrench
- 19mm Socket / Wrench
- Rest on ICON's sheet
Here's the short version. Follow ICON's install sheet (below) for your vehicle's exact steps and torque values. These steps are for part 56503R; the other parts on this page install from their own ICON sheet below.
- Using a properly rated jack, raise the rear of the vehicle and support the frame rails with jack stands. Ensure the jack stands are secure and set properly before lowering the jack. NEVER WORK UNDER AN UNSUPPORTED VEHICLE.
- Install the lower shock mount in the factory location and reinstall the factory lower shock bolt and nut using a 17mm socket/wrench. [Torque to factory spec]
- Install stem hardware as seen in diagram. Tighten the stem nut until it is flush with the top of the stem. Do not overtighten bushing assembly as this can lead to premature bushing wear.
- Mount the remote reservoir to the reservoir mount plate (250000) using the provided (605928) hose clamps. Be sure to install the hose clamp to the recessed ends of the reservoir.
- Thread the supplied (3/8" x 3/4") self tap bolt into the frame rail using a 9/16" socket/wrench, minimum of 2 full rotations.
- Install wheels and lower vehicle back to the ground. [Torque to factory spec]

Warranty, shipping & returns
-
Warranty
ICON covers its shock absorbers, including the shock in every coilover, for 1 year against manufacturer's defects.- Coverage belongs to the original retail buyer who owns the vehicle the part was first installed on.
- A shock that fails in its first year goes to ICON for inspection and service. If ICON finds the cause was neglect, poor installation or anything other than normal wear and tear, the owner pays for labor, parts and shipping.
- ICON repairs or replaces a defective part, at its discretion. Removal, reinstallation, freight and incidental or consequential costs are not covered, and parts that wear in normal use are not treated as defective.
- Not covered: finish (including finish marks from shipping), alterations or modifications, installation that departs from ICON's instructions, racing use, police, taxi, government or commercial vehicles, and sales outside the United States and Canada.
- ICON shocks leave the factory charged with nitrogen. Letting that charge out can make a shock malfunction, and ICON does not cover a failure caused by low nitrogen pressure.
- To claim, contact us first with your order number and a short description of the problem. We open the claim with ICON for you, and your Prestige Truck receipt is the proof of purchase ICON asks for.
