Stock Toyota spindles are a notorious weak point. When you’re airing down or hitting high-speed washboard sections, the factory uprights are prone to bending or even snapping under the stress of larger tires and heavy armor. The APEX Bolt-On Spindle Gussets solve this problem by providing substantial reinforcement to the factory spindle, ensuring your front-end geometry stays true even when the terrain gets rowdy.

Unlike traditional gussets that require a specialized welder, stripping paint, and the risk of melting your ball joint boots, these are a 100% bolt-on solution. They bridge the gap between the upper and lower mounting points, adding the rigidity needed to prevent the spindle from bowing inward during high-compression events.

Key Features

• Structural Integrity: Forged steel construction prevents the factory spindle from bending under the leverage of larger tires (33”+).
• No-Weld Installation: Avoid the heat-stress and downtime of welding; these bolt directly to existing factory points for a shop-proven fit.
• Corrosion Resistance: Finished in a durable texture black powder coat to withstand heavy rain and road salt.
• Sway Bar Compatible: Designed to maintain clearance for most factory and aftermarket sway bar links.
• Trail Security: Provides peace of mind when navigating high-speed desert sections or technical rock crawling where spindle failure can be catastrophic.

What’s Included

• (1) Driver Side Spindle Gusset
• (1) Passenger Side Spindle Gusset
• 12mm or 14mm Caliper Bold Kit (14mm is for 2015-2024 4Runner only)
• (1) 12mm Drill Bit (optional add-on)

• Installation Instructions

Pro Tip: We consider these a really good idea for any Toyota running 35-inch tires or heavy-duty Suspension setups. If you’re already tearing into your front end to install new Upper Control Arms, do these at the same time to save on labor.
