Building on Stage 2's billet UCA foundation, Stage 3 adds the ICON Billet Adjustable Rear Track Bar - a CNC machined 6061 aluminum track bar with FK rod ends and double adjuster threading that allows on-vehicle re-centering of the rear axle at the taller lift height without removal or disassembly. This is a meaningful addition for lifted 4Runners, as the track bar corrects the lateral axle displacement that occurs when the suspension is raised, improving rear suspension geometry, ride quality, and on-road handling precision.\u003c\/p\u003e\u003cp\u003e The rest of the system carries over from Stage 2: billet aluminum Delta Joint Pro UCAs with on-vehicle caster and camber adjustment, 2.5 Series IR front coilovers, front diff drop kit, polyurethane diff bushings, 0.75\" dual-rate rear coil springs for a level front-to-rear stance, and 2.0 Aluminum Series rear shocks with vehicle-specific valving. For the Tubular UCA version of Stage 3, see K53403T. For owners wanting to step up to remote reservoir front and rear shocks (and lower rear links), see Stage 4. Note: does not fit 4Runner models with AVS; ADAS recalibration required; all shocks are 100% rebuildable and re-tunable.\u003c\/p\u003e","brand":"ICON","offers":[{"title":"Default Title","offer_id":53362755502399,"sku":"ICOK53403","price":3649.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/wcaperformance.com\/products\/icon-2025-toyota-4runner-1-25-3in-lift-stage-3-suspension-system-billet-uca","provider":"WCA Performance","version":"1.0","type":"link"}
