Fitment Notes

• Does NOT fit the Ford Bronco Raptor - the Raptor uses a different bolt pattern and wheel specifications
• Bolt pattern: 6x5.5" (6x139.7mm) - verify your specific vehicle's bolt pattern before ordering
• Hub bore: 95.1mm - hub-centric rings may be required for vehicles with a larger factory hub bore (e.g., some Tundra and LX600 applications)
• Offset: +25mm / Backspace: 5.75" - verify brake caliper and fender clearance on lifted builds before ordering
• Professional tire mounting and balancing prior to vehicle installation is strongly recommended
• Sold individually - one wheel per order; a center cap is included
• InnerLock Technology is fully DOT compliant for on-road and off-road use

Features

• Patented InnerLock Technology (U.S. Patent No. 11,090,976) provides a robust internal bead retention system that keeps tire beads secured at low pressures without requiring a traditional external beadlock ring
• Fully DOT compliant - InnerLock delivers the bead security of a beadlock wheel with full street legality, eliminating the need to swap wheels between on-road and off-road use
• Bead retention pins are removable, reusable, and replaceable - constructed from high-strength alloy with thermochemical treatment for extreme corrosion resistance
• Hardened retention pins utilize SAE J1926 O-ring seals for a leak-resistant, long-lasting seal at the pin-to-wheel interface
• Validated against FMVSS No. 139 Tire Bead Unseat Resistance Test at 10 psi - exceeded 7,600 lb machine load limit without de-beading during independent lab testing
• Strength tested to a 3,200 lb load rating - among the highest load ratings in the cast aluminum wheel market
• ICON-optimized offset and backspace dimensions engineered to maximize brake caliper clearance and allow uninhibited suspension travel
• Reduced scrub radius geometry improves all-around handling response and steering feel
• Aluminum alloy construction reduces unsprung weight and rotating mass for improved on- and off-road performance
• Strategically placed InnerLock hardware provides maximum protection from trail damage and rock strikes
• Compatible with a wide variety of tire brands and models without the need for shims or special installation tools

Product Description

The ICON Alloys Rebound Pro in Satin Black (part number 21817859057SB) is a 17x8.5" cast aluminum wheel featuring ICON's patented InnerLock Technology - the same bead retention system used by dedicated off-road racers, now in a fully DOT-compliant package. Traditional beadlock wheels physically clamp the tire's outer bead with an external ring, which requires frequent bolt torque checks, specialty lug patterns, and is illegal for street use in most jurisdictions. The Rebound Pro sidesteps all of those drawbacks by securing the inner bead using a set of removable, corrosion-treated alloy retention pins seated with SAE J1926 O-ring seals. The result is a wheel that allows drivers to run significantly lower tire pressures for improved off-road traction and ride comfort - without sacrificing street legality or adding rotational mass.

Engineered to the same ICON-optimized dimensional standards as the rest of the ICON Alloys lineup, the Rebound Pro's +25mm offset and 5.75" backspace were specifically developed for the 6x5.5" bolt pattern vehicles in ICON's suspension portfolio. This includes the Toyota Tacoma (2016-2024), Toyota Tundra (2022-2025), Toyota Land Cruiser 250 (2024-2025), Toyota 4Runner (2025), Ford Bronco (2021-2025, excluding Raptor), Ford Ranger (2019-2023), Lexus GX550 (2024-2025), and Lexus LX600 (2022-2024). The offset and backspace reduce scrub radius, improving steering precision, and ensure caliper clearance across ICON's full range of lifted suspension systems for these platforms.

The Rebound Pro has been independently tested to exceed 7,600 lbs of bead unseat resistance - surpassing the limits of the test machine - during FMVSS No. 139 Tire Bead Unseat Resistance testing at 10 psi. Its static load rating of 3,200 lbs makes it one of the strongest cast aluminum off-road wheels available. The InnerLock pins are quick to install and remove, require no specialty tools, and are compatible with a wide variety of tire sizes and brands. This wheel is sold individually and includes a center cap. Professional tire mounting and balancing is strongly recommended prior to installation.
