Introducing our fully fabricated spindles, the strongest stock replacement spindles on the market. Designed around the factory OEM spindle geometry, these spindles offer enhanced strength and craftsmanship. Compatible with our long-travel kit, stock length lower arms, and even the stock lower arms, they work seamlessly with 4WD and RWD Prerunner models without modifications. Our 4.0 spindles provide lift and increased track width for RWD owners. We prioritize strength, performance, and articulation, ensuring no compromise for serious off-roaders. With CNC machining, MIG welding, and Faro scanning technology, we guarantee precision and control. These spindles come with stainless braided Kevlar reinforced front brake lines and are ready for installation. For tire size increase, we recommend a zero offset wheel (4.50-4.75" backspacing) for added clearance. Please note that these spindles are not compatible with drop-down bracket lift kits.
