ROAD BOSS 450
Daily Driver/Light Towing
2007.5-2018 Dodge/RAM
Experiencing challenges with reliability when towing or during daily driving can lead to frustration and limited use of your truck. With trucks up to 450 horsepower, standard transmissions may struggle, especially when handling occasional loads up to 12,000 lbs, impacting your vehicle's performance and confidence on the road.
Our transmission build is tailored for the daily driver who requires reliable performance and occasional light towing without sacrificing dependability. Enhanced with performance upgrades, this transmission matches the price of a typical stock rebuild but provides superior durability and smoother yet firmer shifts. Ideal for stock-size tires, it ensures consistent power transfer and a comfortable driving experience.
This upgrade offers peace of mind by maintaining efficiency and control whether you're commuting or hauling light loads, giving you the best of both worlds: affordability and performance. Rated at up to 450HP
Horsepower Rating: 450 rear wheel

How RedLine Builds it Better
How RedLine Builds It Better!
Expert Craftsmanship
Every transmission is hand-built by seasoned builders who understand the difference between “good enough” and “overbuilt.” We believe in going the overbuild route. Instead of rushing jobs or using cookie-cutter rebuild kits, RedLine takes the time to precision-machine, measure, and assemble each unit so it’s tuned to last tens of thousands of miles under real-world stress.
Specific Brand & Platform Knowledge
You don’t just “do transmissions.” You specialize in Cummins Dodge/RAM and Duramax Chevy/GMC platforms, which means you know the quirks, weak points, and exact part combinations that actually work in these trucks. This expertise ensures builds are not only stronger but also tailored for each application—whether it’s towing, daily driving, or performance horsepower.
Proprietary Build Recipes & Tested Combinations
RedLine has developed its own proven build recipes (ROAD BOSS 450, TOW BOSS 550, HD BOSS 700, TRACK BOSS 900 and 1200 COMPETITION BOSS) that eliminate factory weak points and balance performance with durability. These aren’t off-the-shelf packages—they’re field-tested setups refined over thousands of transmissions, backed by real-world data and customer feedback.
Real-World Testing & Validation
Before a RedLine transmission goes out the door, it’s not just assembled—it’s tested, validated, and proven under real-world conditions. From line pressure checks to hot flush verification and test-drives, every unit is verified to perform the way it should. This extra layer of quality control ensures customers drive away with confidence, knowing their build has already been put through its paces.
