Trailer Hitch Installation Techniques
Watch for hardware order, washer stack, and final torque mindset. Pause when the video shows you supporting the hitch while you start bolts so the sheet and the car agree.
Watch on YouTube →Hitch Bolt Torque Tips (Canada)
Just bolted a CURT hitch under a Canadian car, truck, or SUV and wondering how tight is tight enough? Hitch hardware needs proper torque because the receiver carries bike-rack bounce, trailer tongue weight, and winter frost heave on rough roads. Follow the CURT instruction sheet for your exact SKU for the torque values, then recheck the fasteners after the first trips. This page does not invent foot-pound numbers. It explains why torque matters, how to use the sheet, and how to pair the weekend install checklist with CURT install videos before you call the job done.

How to Trim Fascia on a Vehicle
Fascia work happens before final torque on many cards. Trim carefully, then come back to the torque table on the instruction sheet for your SKU.
Watch on YouTube →Why hitch hardware needs proper torque
A hitch is not a decorative bumper brace. Every pothole, railroad crossing, and bike-rack bounce tries to work fasteners loose. Undertorqued bolts can frett the frame holes, elongate slots, and leave you with a rattling receiver. Overtorqued bolts can stretch threads, crush sleeves, or crack brackets on unibody cars. The CURT instruction sheet for your SKU exists so you land between those two failure modes with the hardware that shipped in the box.
Canadian winters add salt, freeze-thaw, and seized factory nuts. Penetrating oil and patience beat an impact gun on a rusty captive nut. Clean the threads you can see, start every bolt by hand, then finish with a calibrated torque wrench to the values printed for that part number. A “good and tight” feel with a breaker bar is not the same as following the sheet.
Follow the CURT instruction sheet for your SKU
Write down the five-digit CURT part number from the box or packing list. Download or unfold the instruction sheet that matches that number. The torque table on that sheet is the authority for your hitch, not a forum post for a different year and not a generic Class chart. Different SKUs use different bolt grades, sleeve stacks, and frame attachments, so values are not interchangeable.
If the sheet and a YouTube video disagree, trust the sheet for your SKU. Videos teach habits. The PDF lists the numbers. For help finding the right install clip, open how to use CURT install videos and search the official CURT channel for your part number first.
Step 1Match the SKU sheet
Confirm the instruction PDF part number matches the hitch you installed before you reach for a torque wrench.
Step 2Stage the right tools
Use a torque wrench that covers the range on the sheet, the correct sockets, and a helper to support the hitch.
Step 3Torque in the sheet order
Follow the numbered hardware sequence. Snug first, then final torque. Do not invent a different order.
Step 4Recheck after first trips
After the first short drives with a rack or empty trailer, recheck the fasteners to the same sheet values.
Recheck after the first trips
New hardware can settle once the hitch sees real road vibration. After the first few trips, or after the first weekend with a loaded bike rack, put the vehicle back on stands or a lift and recheck every fastener to the sheet values. Many shops do this as a free courtesy check when you come back for wiring. It is cheap insurance either way.
Make rechecks part of seasonal habits too. Before a long cottage weekend in spring, and again before winter storage, glance for rust streaks, missing lock washers, and a receiver that has shifted. If anything moved, stop using the hitch until the hardware is corrected with the sheet in hand.
| Topic | What we tell shoppers |
|---|---|
| No invented numbers | We will not print foot-pound guesses on this page. Use the torque table on the CURT instruction sheet for your SKU. |
| Calibrated wrench | Click-type or digital torque wrenches beat “feels tight.” Borrow or rent one if you do not own a wrench that covers the sheet range. |
| Dry versus lubricated | Follow the sheet notes on dry threads versus lubricated threads. Changing that assumption changes clamp load. |
| Hardware kit only | Use the bolts, spacers, and washers that shipped with the hitch unless the sheet says otherwise. Random hardware-store bolts are not a plan. |
| Impact guns | An impact can start rusty nuts, but final torque belongs on a torque wrench. Snug is not finished. |
| Fascia first | Finish bumper-cover trim and exhaust clearance checks before you call torque done. See fascia trim tips. |
| Checklist pair | Print the weekend install checklist so torque is a written step, not a memory. |
| When to call a shop | Rounded bolts, cracked brackets, or orange EV cables near the work area are shop territory. Paying for a clean torque job beats a loose receiver. |

A simple Canada torque workflow
Day before: download the instruction sheet for your SKU, watch the CURT install techniques video once, and confirm your torque wrench covers the printed range. Install day: support the hitch, start bolts by hand, snug in the sheet order, then final-torque to the printed values. After the first trips: recheck every fastener to the same numbers, then enjoy the rack or trailer without wondering if something is walking loose.
If you bought the hitch from Lots of Parts, keep the packing list handy so the SKU on the invoice matches the sheet on the driveway. Free shipping on live CURT gear does not change the need for careful torque habits.
