VRP M113/M113K TO DODGE ZF 8HP70 COMPLETE SWAP KIT
THE ULTIMATE M113K TRANSMISSION UPGRADE
Replace the aging 722.6 5-speed automatic with the legendary Dodge ZF 8HP70 – the same transmission trusted in 700+ horsepower Hellcat applications. Stronger, faster, more gears, better fuel economy.
Everything included except transmission and driveshaft.
WHY DODGE 8HP70?
The 8HP70 handles 750+ lb-ft of torque – proven in Hellcat, Demon, and TRX applications – making it perfect for supercharged M113K builds that have outgrown the 465 lb-ft capacity of the 722.6. With lightning-fast shifts, electronic adaptive control, and launch control capability, this modern 8-speed delivers better performance and fuel economy than the outdated 5-speed. Best of all, transmissions are abundant in the US at $500-$1,500 used, making this swap both powerful and affordable.
