THREE SIX SOLUTIONS provides upgrades to your GM 3.6-equipped vehicle!


With our LLT to LFX retrofit kit, you can easily install a 2018-2022 engine into your 2009-2017 car or SUV!!


Why do the swap?


==>> MORE POWER!!! The newer LFX has higher compression and provides up to 30 more hp than your LLT!!  You will notice a considerable boost, primarily on the top end!  The factory computer controls compensate for the compression difference, no problem.  You will have no check engine light on and everything g will be plug-and-play!!


==>> Smoother running!! GM has taken measures such a a more rigid timing cover, revised internals and timing components, and has done a great job making these engine EVEN smoother!!  BRAVO GM!!  We love you!!


==>> NO WORRIES ABOUT TIMING ISSUES!! All the bugs have finally been worked out!  This engine is far superior to the LLT!!


==>> Better fuel economy!! With the exhaust manifold being integral to the cylinder head on the newer LFX, which essentially is liquid-cooling the exhaust, this allows the engine computer to run the engine at a slightly leaner fuel-air ratio, which equates to more power and better fuel economy!


==>> LOWER COST!!  Due the fact these LFX engines are so good, they are not failing like the LLT and thus there is a surplus in supply.  Due the laws of supply and demand, this excess in supply means much lower cost to you!!  We recommend you find your LFX engine on www-car-part.com, which is the national locator for all the engine recycle centers.  Many recycle facility are selling their surplus of LFX engines as low as $500/ea for a low mileage engine, with 10-30k!!  An LLT with comparable miles would be more in the range of $3500-4000!!
