Tech Notes & Fitment

• Receiver size: Most 2500/3500 receivers use 2.0" or 2.5" openings—match your ball mount/shank.
• Level & load: Air springs help keep ride height/caster where it belongs under tongue weight; re-aim headlights after setup.
• Monitoring: Watch EGT and transmission temperature on grades; add a trans temp gauge or digital monitor.
• Competition vs. street: Sled/pulling hitches and kill switches are for competition/off-road. Follow your sanctioning body’s rulebook.

Frequently Asked Questions

Do I need air springs for a travel trailer or equipment trailer?

They’re highly recommended. Air helpers like Air Lift 57295 or Firestone 2299 level the truck, improve stability, and can reduce headlight glare.

What size hitch should I run—2" or 2.5"?

Match the receiver on your Ram. Many HD receivers are 2.5"; use a reducer sleeve for 2.0" shanks if needed. Check the label for max GTW and tongue weight.

What gauges are most important for towing with a 5.9L?

Prioritize EGT (pyrometer) and transmission temp; fuel pressure and boost are helpful too. See Gauges / Related for 03–07-specific options.

Is a competition sled hitch legal for street towing?

No. Competition hitches and kill switches are for sanctioned events. For street towing, use a DOT-legal receiver/ball mount and follow weight ratings and local laws.
