Improve cooling efficiency and engine performance with dual coolers. The ROUSH Low Temp Radiator Upgrade (Upper LTR) is designed specifically for those owners of 2011-2013 5.0L and 6.2L Ford F-150’s, equipped with a ROUSH R2300 Supercharger and Lower LTR.
The ROUSH Upper LTR is a simple add-on kit that seamlessly integrates with the Lower (smaller) LTR. Dual LTRs provide more effective air cooling by increasing the heat transfer surface area, which results in lower intercooler water temperatures and provides superior air charge cooling. Adding the Upper LTR brings the total surface area to 422 in. sq. and also provides 1 qt. of additional cooling volume, leading to lower inlet temperatures.
ROUSH engineers spent many hours developing and testing the Upper LTR to achieve maximum temperature reductions. During wide-open throttle runs, the manifold charge temperatures were reduced by 45 degree F when running the dual LTR set-up. Steady state driving tests also shown on average that dual LTRs reduced inlet air temperatures by 27 degree F over lower LTR-only usage.
The all-aluminum design also allows for quick and easy installation.
All of the necessary hardware is included in the Upper LTR Kit:
