The FOX Performance Elite 2.5 Remote Reservoir Coilover System with UCA is engineered for Silverado and Sierra 1500 owners who demand precise damping control, improved chassis stability, and long‑term durability across every terrain. The oversized 2.5" hard‑anodized aluminum shock body increases oil capacity for superior heat dissipation, allowing the suspension to maintain consistent damping during repeated impacts, high‑speed terrain, and extended off‑road use.
The external remote reservoir separates the nitrogen charge from the main shock body, reducing cavitation and ensuring stable performance under load. FOX’s Performance Elite valving sharpens steering response, improves chassis control, and smooths out rough terrain — ideal for trucks equipped with armor, recovery gear, or overland accessories.
This system includes upgraded upper control arms engineered to maintain proper caster, alignment stability, and full droop travel. Lift height varies by trim:
-
3.5" Lift on NON‑AT4 / NON‑Trail Boss models
-
1.5" Lift on AT4 / Trail Boss models
This ensures correct geometry, predictable handling, and maximum usable suspension travel across all configurations.
With 4.05" of controlled suspension travel, this system delivers a balanced blend of off‑road capability and refined on‑road manners, making it a strong upgrade for daily drivers, tow rigs, and off‑road builds alike.
Free shipping on all orders.
Why This Is a Strong Upgrade
-
Massive increase in damping authority: The 2.5" shock body dramatically increases oil volume, reducing fade and improving control compared to stock or 2.0‑series shocks.
-
Remote reservoir = sustained performance: Enhanced heat management and reduced cavitation keep damping consistent during long off‑road runs or loaded travel.
-
Sharper steering and chassis stability: Performance Elite valving improves steering response, reduces body movement, and enhances high‑speed stability.
-
Ideal for added weight: Perfect for trucks running bumpers, winches, skids, racks, or other heavy accessories.
-
UCA included for full geometry correction: Restores caster, stabilizes alignment, and unlocks full droop travel.
-
Daily‑driver refinement: Despite the performance capability, the system maintains smooth, controlled on‑road manners.
