68RFE Heavy-Duty Options for Built Ram Cummins: BD TrackMaster & Core Upgrades

If you’re turning up the 6.7L Cummins—or you tow heavy and hard—the 68RFE needs real fixes. Here’s BD’s high-performance path: a stronger valve body, smarter pressure control, billet hard parts, more clutch area, cooler temps, and a multi-disc converter that holds without harsh lockup.

Quick Summary: Built power + big loads overwhelm stock 68RFE with cross-leaks, OD clutch slip, and weak hardware. BD’s TrackMaster packages add a ProTech68 valve body (to ~250 psi on load), billet/sleeved problem bores, heavy-duty drums/shafts/plates, 33%+ more clutch capacity in key elements, a deep pan (+4.5 qt), and a ProForce 3D multi-disc converter that stays smooth yet strong.

Which BD Build Fits a High-Performance Cummins?

  • TrackMaster 68RFE (2007.5–2018) — For tuned/worked trucks that see heavy towing or spirited use. Adds BD’s full clutch-capacity, pressure, and billet hardware strategy. View package →
  • TrackMaster 68RFE (2019–2024) — Same BD approach, fitment for later trucks. View package →

Building for maximum longevity with moderate power? Pair a BD valve body and converter with cooling upgrades. Pushing power + weight? Go TrackMaster.

Why the 68RFE Struggles as Power Goes Up

  • Cross-leaks & worn SSV bore bleed pressure → soft applies, hot clutches.
  • Overdrive section lacks apply area from the factory → slips under load/tune.
  • Accumulator plate blowout and weak sprag/retainers under shock loads.
  • Heat—thin pan capacity and long grades raise temp, shorten fluid/clutch life.

What BD Changes Inside a TrackMaster 68RFE

  • ProTech68 valve body with gasketed separator plate to stop cross-leaks; steel-sleeved SSV bore and machined/sleeved TCC limit valve target known wear points.
  • ProTech68 pressure controller ramps line to ~250 psi referenced to MAP load—pressure is there when you need it.
  • Clutch capacity increase: additional frictions where it counts (e.g., ~33% more C2 & OD), QT100 billet pressure plates reduce deflection/heat.
  • Big Stack OD clutch with HD billet OD drum & 16-surface OD shaft for a massive OD apply gain—key for tow and tune.
  • Billet hardware: 4C spring retainer, 2C piston girdle; HD cam & roller low-reverse sprag for shock load durability.
  • Deep aluminum pan adds ~+4.5 qt capacity for cooler, stabler temps on grades and in hot climates.
  • ProForce 3D multi-disc converter: increased clutch surface (three-surface lockup), forged one-piece cover, HD springs and bearings; smooth OEM-like drivability without the typical harsh lockup surge.

Who Should Choose TrackMaster?

  • Tow + Tune owners who want reliable OD and repeatable lockup on grades.
  • Built work trucks that see frequent heavy loads, heat, and shock events.
  • Weekend performance users that still daily/tow—wanting strong yet civilized shifting/lockup.

Supporting Upgrades That Finish the Job

  • Valve Body Upgrade (standalone): Already have a good core? BD’s 68RFE valve body adds the sleeved SSV bore, bonded plate, new accumulator pistons/plate, and an OEM solenoid for consistent pressure and clean shifts. See details →
  • Cooling & service: Use the deep pan’s drain to shorten service intervals; keep cooler and lines clean; verify cooler flow after any failure.
  • TCM strategy & learn: After major work, perform the adaptive/quick-learn procedure and confirm latest calibrations.

2007.5–2018 vs 2019–2024 Fitment

BD offers TrackMaster packages tailored to each generation’s harness/controls and fitment. Choose the link that matches your model year:

• TrackMaster 68RFE 2007.5–2018
• TrackMaster 68RFE 2019–2024

Why BD for a Built 68RFE?

Because BD doesn’t band-aid symptoms—they re-engineer the causes: sealing and pressure integrity, hard-part strength, real apply area, thermal control, and converter clutch capacity that locks hard without driving harsh. Every TrackMaster package is dyno tested before it ships.
