Part # 421580

Stay cooler longer with dual coolers! The ROUSH Low Temp Radiator Upgrade (Lower LTR) is designed specifically for those owners of 2011-2014 5.0L and 6.2L Ford F-150's, equipped with a ROUSH R2300 Supercharger and Upper (large) LTR.

The ROUSH Lower LTR is a simple add-on kit that seamlessly integrates with the current, large-face Upper LTR. Dual LTRs provide more efficient air cooling by increasing the heat transfer surface area, which results in lower intercooler water temperatures and provides superior air charge cooling. Adding the Lower 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 Lower LTR to achieve maximum temperature reductions. During wide-open throttle runs, the manifold charge temperatures were reduced when running the dual LTR set-up. The compact, all-aluminum design also allows for quick and easy installation.

All of the necessary hardware is included in the Lower LTR Kit: Low Temp Radiator 3/4" Connecting Hose Mounting Bracket and Hardware Kit

This kit is protected by the ROUSH 90-Day Limited Warranty (ROUSH supplied parts only) from date of purchase.
