Stock Mopar 6.2L Hellcat SRT8 Shortblock

The 6.2L Hellcat engine features a completely forged rotating assembly, unlike the stock 6.4L, 392 pistons which are hyperkinetic. From the factory this bottom end supports the Hellcat’s 707 crank horse power. Dodge is so confident in this configuration that it gives the Hellcat a 3 year / 36,000-mile powertrain warranty. The 6.2L features a 4.090" Bore & a 3.580" Stroke.

Key Features

  • Pistons: Hellcat pistons are forged aluminum, with increased radii in center for added strength. The wrist pins have a diamond like coating improving contact pressure capabilities. Slightly dished to lower compression to 9.5. Larger ring lands ensuring durability. Similar to the Apache piston, the skirts come coated. The skirts on the Hellcat piston are notably larger.
  • Connecting Rod: The Hellcat rod is a full floating, powdered steel connecting rod with a bronze bushing. Chrysler upgraded the alloy for this rod over the stock 6.4L Apache. The top end of the connecting rod is tapered to reduce inertial mass.
  • Crankshaft: Forged, micro polished, induction hardened, and fillet rolled! Every hellcat crank has the main journals measured and based on that measurement one of 3 custom main bearings is selected, ensuring that no matter the variance in tolerance the main bearing is a perfect fit.
  • Block: The block is cast utilizing a high strength alloy and features water jackets that are extended to the piston’s bottom dead center location, providing optimal heat transfer capabilities. Additional material and webbing between the main bulk heads and on exterior faces add strength and rigidity.

  • Our Quality
A2Speed is an employee owned automotive performance parts company, specializing in the Gen III HEMI engine and the cars & trucks it powers. Just like you we are Hemi enthusiasts, and like you we are only interested in proven performance solutions. Good enough isn’t. People who invest in performance modifications want parts that last decades, not years. The effort is only valuable if the result is better than good enough, and frankly these days that’s hard to do.

A2Speed’s GEN III HEMI Background

Many of us at A2Speed have been working on the Gen III since its inception. As a team we are immersed in the Hemi world. We own, drive, modify, race and occasionally…break them. We use this experience to create SOLUTIONS, not just parts. Automotive engineering has advanced such that it is often difficult to improve on the work done by the OEMs. Difficult, not impossible. Utilizing advanced 3D modeling, CFD and stress simulations coupled with rapid prototyping, allow for the development of specialized parts that would be impractical at OEM volumes. Solutions validated with real world testing. Craftsmen level quality; and because we don’t have the layered overhead, our prices are often at or below the OEM price.

Advanced Aerospace Grade Machining

Production manufacturing is performed by partner companies that have proven track records for quality and timely deliveries. We look for certifications such as ISO-9001 and AS-9100 along with ITAR and GIDEP registrations. Several of the companies we work with regularly supply major aerospace firms and the DOD. Why use outside machining services? So that you get a better part at a better price. By utilizing only the machine cycles we need, and leveraging the superior skills and years of experience, A2Speed can give you exceptional quality at truly affordable prices.
