NEW lower Prices on  Arrington Performance Stroker Engines

Arrington Performance is bringing our winning combinations to you at a new low price you can’t resist. API and ShopHEMI.com has worked with our suppliers to bring you the best HEMI stroker engines on the market at a price you can’t beat. We use crankshafts and connecting rods from 4340 forgings, machined on state of the art CNC machining centers, heat treated to increase tensile strength, shot peened to improve fatigue life, nitride treated to increase wear resistance and 100% magnafulx particle inspected to insure there are no imperfections. Our Pistons were custom designed incorporating state of the art advances like an anodized Top Ring groove to prevent excessive wear and reduce piston ring friction and properly chamfered valve reliefs that eliminate all thin and sharp edges preventing them from breaking off into the engine under heat and stress. These engines still feature the NASCAR proven engine building, machining, and designing not even mentioned here. These engine components, a 30,000 mile warranty, and our precise machining capabilities and attention to detail ensure that when we assemble your HEMI engine, we get it right the first time, every time.

Molnar Technologies crankshafts are manufactured from 4340 forgings, machined on state of the art CNC machining centers, heat treated to increase tensile strength, shot peened to improve fatigue life, nitride treated to increase wear resistance and 100% magnafulx particle inspected to insure there are no imperfections. Molnar Technologies connecting rods are manufactured from 4340 billet steel, fully machined on state of the art CNC machining centers, heat treated to increase tensile strength, shot peened to improve fatigue life, 100% magnaflux particle inspected to insure there are no imperfections and finish machined to the tightest tolerances in the industry. Molnar Technologies rods may look like many of the other H-beam rods on the market but feature an exclusive beam design that puts mass only in heaviest loaded part of the rod without adding extra weight. This results in one of the strongest rods on the market while still being one of the lightest rods available. These rods come standard with ARP rod bolts designed with a special thread profile to equally load the threads and reduce the possibility of breakage even in extreme applications. Mahle Piston Company has provided us with one of the best piston designs on the market specifically designed for Arrington’s late model HEMI engines. Valve reliefs are properly chamfered eliminating all thin and sharp edges of Aluminum eliminating them from breaking off into the engine under heat and stress. These pistons come standard with an anodized Top Ring groove to prevent excessive wear and reduce piston ring friction allowing them to rotate as needed. A compact design with a special Grafal Coating ensures less wear, the ability to run tighter clearances, and results in quieter engines with less weight and more power. Clevite bearings are our HEMI engine builder’s bearing of choice and have proven themselves time and time again with our high revving NASCAR Engine development research. These engine components along with our precise machining capabilities and attention to detail ensure that when we assemble your HEMI engine, we get it right the first time, every time.

When you decide to go with an Arrington Performance HEMI Engine for your build, you are being backed by the largest HEMI Performance Part supplier in the world. From the beginning assembly to the final tuning Arrington provides you with the resources to get it done.
