TDP ALLISON 1000 750HP

TDP Allison 1000 750HP Performance Build 

Built for trucks that actually get used. This 750HP Allison 1000 is designed to handle aggressive street driving, towing under load, and tuned applications without the common factory failures.

This isn’t a “stage package” with fluff — it’s a purpose-built unit with the right hard parts and clutch capacity to reliably support up to ~750 horsepower.

What Sets This Build Apart

• GPZ Clutch Packs (C1–C5 + Module)
  Increased holding capacity and heat resistance over stock materials. Built to handle higher line pressure and power levels without slipping.
• 300M Billet Input Shaft
  Eliminates a major failure point in higher horsepower trucks.
• Billet C2 Clutch Hub
  Strength where it matters — prevents hub failure under load and tuning.
• Goerend Performance Converter
  Triple-disc billet converter for solid lockup, reduced slip, and better power transfer.
• RatioTek Valve Body Kit
  Improved hydraulic control for firmer, more consistent shifts and increased clutch apply pressure.
• Complete Overhaul Kit (Bonded Pistons)
  New seals, gaskets, and pistons to ensure long-term reliability and proper sealing.
• Bearing & Bushing Kit
  Restores proper tolerances throughout the unit.
• Deep Pan
  Increased fluid capacity = better cooling and longer life.
• New Internal Harness + Filters
  Eliminates electrical issues and keeps fluid clean.
• Updated Retainers + PTO Cover
  Improved durability and oiling support.
