At T3 Speed Shop, we treat your RAM Cummins as more than just a truck—it’s a medium-duty engine in a light-duty frame, designed for unmatched work capacity. Leveraging 50 years of combined local expertise and dealer-level diagnostic technology, we provide the proactive maintenance and high-performance engineering required to keep your 5.9L or 6.7L "powerplant" running with absolute reliability.
We follow a philosophy that proactive maintenance prevents reactive repairs. Our high-altitude service intervals are designed to protect your investment from Utah’s extreme grades and temperatures.
Maintenance Schedules: Precise oil, fuel filter, and air filter services at 7,500 and 15,000-mile intervals to maximize engine life.
Fluid Analysis & BG Products: Utilizing high-quality BG fluid exchanges to enhance engine longevity and prevent internal sludge.
The "Killer Dowel Pin" (KDP) Fix: Essential preventative service for 12-valve and early 24-valve engines to prevent catastrophic timing gear failure.
CP3 Conversions: We replace vulnerable CP4 pumps with the ultra-reliable CP3 to protect your entire fuel system from metal contamination.
A Cummins is only as strong as its air and fuel delivery. We use Snap-On, Autel, and OEM-level scanners to pinpoint issues without the guesswork.
Fuel Injection Specialists: Expert diagnostics for hard starts, long crank times, and rough idles. We test and replace injectors, fuel rails, and high-pressure pumps.
VGT & Turbo Solutions: We solve "lazy" response and limp mode issues by servicing Variable Geometry Turbo (VGT) actuators, cleaning clogged vanes, or installing compound turbo setups.
Precision Air Intake Service: From intercooler boot and piping kits to S&B cold air intakes, we ensure your engine breathes clean, dense air.
Keeping your truck compliant and efficient is a priority. We specialize in the complex after-treatment systems found on 2007.5+ models.
DPF & SCR Diagnostics: We resolve frequent regeneration cycles, clogged Diesel Particulate Filters, and DEF sensor/heater failures.
EGR System Health: Inspection and cleaning of EGR valves and coolers to prevent soot buildup and overheating.
State & DOT Inspections: Comprehensive OBD emissions testing and on-the-spot renewals to keep you road-legal.
Your engine’s torque is only useful if it reaches the ground. We strengthen every link in the chain.
Transmission Optimization: We service Aisin and Mopar transmissions, addressing pressure solenoid failures, torque converter shudder, and seal leaks.
Chassis & Steering Excellence: We are Utah’s premier installers for Carli and Thuren suspension systems, eliminating the "Death Wobble" and correcting rear-end sag for heavy towing.
Brake & Hub Service: Comprehensive inspections and heavy-duty pad/rotor replacements for maximum safety under load.
Dealer-Level Tech, Local Shop Heart: We use the same advanced equipment as the big dealerships (Hunter Alignments, Digital Vehicle Inspections) but with the transparency of a family-owned shop.
Specialized Expertise: While others are "general" mechanics, we focus exclusively on the specific nuances of the Cummins 5.9L and 6.7L platforms.
Towing & Convenience: After-hours key drop-off and professional towing services ensure your truck gets to us even when you can't drive it.
5th Gen (2019-Present): High-output maintenance and "must-have" reliability mods.
4th Gen (2013-2018): Emissions system diagnostics and suspension leveling.
3rd Gen (2003-2012): Fuel system upgrades and turbocharger rebuilds.
