CURT builds towing equipment, not building materials. Their core business: Manufacturing of custom-fit trailer hitches, towing products, and truck accessories. While that might seem odd for Western Building Center to carry, here’s why it matters: Montana contractors haul equipment constantly. From Kalispell to Great Falls, you need reliable connections between your truck and whatever you’re dragging to the jobsite.
The Towing Line That Contractors Actually Use
CURT’s Tri-Ball Hitch mounts three different ball sizes (1-7/8”, 2”, 2-5/16”) on one adjustable unit. No more swapping ball mounts when you switch from the utility trailer to the equipment hauler. Weight ratings range from 5,000 lbs GTW on the small ball up to 10,000 lbs GTW on the 2-5/16” ball. The adjustable model weighs 45.41 pounds — built like a tank because it needs to be.
Their trailer balls come in every configuration contractors need. The 2” balls handle up to 6,000 lbs with 1” x 3” shanks. Heavy-duty options go higher. Chrome-plated finishes resist Montana’s road salt and weather extremes. Fine threads provide enhanced holding power — coarse threads strip out under load.
For mixed fleet operations, CURT makes 7-blade to 4-flat electrical adapters that connect RV-style sockets to basic utility trailers. Model 57004 includes integrated resistors for LED trailer light recognition — solves that annoying fast-blink problem on newer trucks. Plug-and-play design: eliminates the need for cutting or splicing.
Security and Safety Systems Worth the Investment
Tool theft at jobsites is epidemic. CURT’s 5/8” hitch locks are tested to 21,000 lbs. Chrome-plated carbon steel construction handles weather. Barbell design prevents pin tampering — thieves can’t just knock the pin out with a hammer.
DOT requires breakaway systems on trailers over 3,000 lbs GTW. CURT’s Soft-Trac systems work for up to 3-axle trailers, include a 12V, 5-amp rechargeable battery, and install with one bolt without cutting. 48” lanyard provides proper activation distance — too short and it activates during tight turns, too long and it won’t engage when needed.

Manufacturing That Backs Up the Specs
USA-made manufacturing (all products manufactured domestically). Advanced robotic welding stations for precision and consistency. Proprietary co-cured finishing process with mechanical/chemical descaling, liquid submersion undercoating, and powder coating for superior corrosion resistance. That finishing process matters when your equipment sits outside through Montana winters.
Part of Lippert Components, Inc. — gives them the scale to maintain inventory and distribution. Over 1,000 different models for nearly every non-commercial vehicle in North America. They’ve been making hitches since 1995.
Who Should Buy CURT (And Who Shouldn’t)
Buy CURT if you’re hauling expensive equipment and need it to arrive intact. Their weight ratings are conservative. The chrome finishes hold up. The engineering shows in details like proper thread pitch and integrated resistors for LED compatibility.
Skip CURT if you’re pulling a utility trailer twice a year for dump runs. Basic trailer balls work fine for light-duty applications. But when your livelihood depends on that connection between truck and trailer — when you’re hauling a mini excavator over Marias Pass — quality becomes critical.
Professional contractors generally view the CURT Tri-Ball Hitch as a versatile and reliable towing accessory, with its primary strength being its ability to accommodate multiple ball sizes in a single, adjustable unit. Its main advantage is flexibility, allowing users to switch between different trailer couplers without needing multiple hitches.
Frequently Asked Questions
Q: What torque should I use on CURT trailer balls? A: 250 ft-lbs for 1” shanks, 450 ft-lbs for 1-1/4” shanks. Under-torquing is dangerous. Over-torquing strips threads. Use a proper torque wrench.
Q: Will CURT’s electrical adapters work with LED trailer lights? A: Model 57004 includes integrated resistors specifically for LED trailer light recognition. Without resistors, LEDs can cause hyperflashing or error codes on modern trucks.
Q: Are CURT hitches actually rated for their listed capacity? A: CURT products undergo thorough testing to support their rated loads — the 21506 pin supports up to 21,000 lbs. Their commitment is demonstrated through rigorous in-house testing standards, ensuring all products are proven safe and dependable.
Q: Do I need a breakaway system for my equipment trailer? A: Required by DOT for trailers over 3,000 lbs GTW. CURT’s Soft-Trac systems handle up to 3-axle trailers. Even if you’re under the weight limit, it’s cheap insurance against runaway trailer disasters.
Q: Why does the adjustable Tri-Ball weigh so much more? A: The adjustable model weighs 45.41 lbs versus 19.0 lbs for the solid shank version. The adjustment mechanism adds steel. That extra weight means extra strength for heavy-duty towing.
