Equal-i-zer vs CURT TruTrack
Both offer integrated weight distribution and sway resistance, but their hitch-head mechanisms, model families, and setup tradeoffs are not identical.
Compare Current OptionsThe names sound similar because both systems use weight-distribution spring bars and integrated sway resistance. But calling them identical “four-point friction hitches” hides a useful engineering difference: Equal-i-zer relies on friction at its head sockets and L-brackets, while CURT describes the TruTrack 4P as a spring-and-cam head system plus bracket friction. This comparison starts with that distinction, then works through ratings, setup, and real ownership.

01 Quick picks by system and rating
These are five documented configurations from three distinct control arrangements—not five independent hitch technologies. Compare models only after measuring loaded tongue weight.
The L-bracket interfaces and hitch-head sockets both contribute friction. This differs from CURT’s cam-assisted 4P head.
CURT describes hardened cam elements in the head plus friction at fixed spring-bar support brackets.
Same basic friction-control family, but a different spring-arm and head rating must be selected as a matched system.
CURT publishes both a tongue-weight operating range and 15K upper gross trailer weight rating for this part.
The 2P relies on two fixed bracket friction points; CURT explicitly says it does not use the 4P spring-and-cam head.
02 Equal-i-zer vs TruTrack comparison table
Ratings are model-specific manufacturer listings, not towing permissions. Always follow the lowest-rated component and the vehicle manufacturer’s weight-distribution guidance.
| Configuration | Sway-control mechanism | Published weight class | Key tradeoff |
|---|---|---|---|
| Equal-i-zer Original 4-Point — 10K | 4-point: head sockets + L-brackets | 10,000 lb GTW / 1,000 lb TW model | Frame bracket position, turning noise, and head-socket lubrication are part of ownership. |
| CURT TruTrack 4P — 17500 | 4-point: spring/cam head + fixed brackets | 10,000 lb GTW / 1,000 lb TW model | Do not assume head maintenance, bracket geometry, or replacement parts are interchangeable with Equal-i-zer. |
| Equal-i-zer Original 4-Point — 12K | 4-point: head sockets + L-brackets | 12,000 lb GTW / 1,200 lb TW model | A higher label rating does not increase the tow vehicle, receiver, or trailer limits; oversized bars may be a poor match. |
| CURT TruTrack 4P — 17501 | 4-point: spring/cam head + fixed brackets | 10,000–15,000 lb GTW / 1,000–1,500 lb TW | At 1,000 lb TW minimum, it is not an automatic choice for lighter trailers. |
| CURT TruTrack 2P — 17601 | 2-point: bracket friction only | Up to 10,000 lb GTW / 1,000 lb TW | Do not mistake the 2P for a direct four-point competitor or assume equal sway-control behavior. |
03 Detailed model comparison
Use the correct rating and full kit configuration; a model number, shank inclusion, and trailer-ball inclusion can change what is actually in the box.

Check Price04 Which mechanism should you choose?
Choose by hitch-head design, not the number “four” alone
Equal-i-zer: the spring bars interact with L-brackets on the trailer frame and sockets in the hitch head. Manufacturer maintenance instructions specifically call for lubricating the socket-to-head friction surfaces; the L-bracket surfaces are not routinely greased. This is a defined ownership routine, not a claim that one hitch never makes noise.
TruTrack 4P: CURT describes a spring-and-cam system at the head, with fixed support brackets providing additional lateral resistance. Its design is mechanically distinct, and its instructions should control setup and lubrication. Do not transfer Equal-i-zer washer settings or lubrication habits to CURT.
TruTrack 2P: CURT describes bracket friction without the 4P head cam. It can be a valid choice in its own right, but a 2P listing should never be silently compared as though it were the same 4P system.
Three real-world scenarios
- You tow a conventional travel trailer and value documented friction maintenance: shortlist the appropriately rated Equal-i-zer, then confirm frame clearance and fit.
- You want a different four-point head mechanism: compare the same weight class against CURT TruTrack 4P; check bracket mounting space and the exact CURT installation sheet.
- You see a cheaper TruTrack listing: inspect the model number before deciding; it might be a 2P rather than the 4P system you intended to compare.
05 Five checks before buying either hitch
- Weigh the loaded trailer: use actual loaded tongue weight, including any weight behind the tow vehicle’s rear axle that the hitch maker directs you to include; do not size from dry tongue weight alone.
- Check the complete tow rating chain: tow vehicle, receiver (including its weight-distribution rating), ball, shank, coupler, trailer, and hitch. The lowest applicable limit controls.
- Confirm the tow vehicle permits weight distribution: some vehicles or receivers restrict it; never assume a higher-rated hitch upgrades the vehicle.
- Inspect trailer A-frame clearance: propane trays, battery boxes, jack hardware and frame geometry can obstruct bracket locations.
- Follow the exact manual for setup and maintenance: initial adjustment, head tilt, bracket height, torque, lubrication and rechecks vary by brand and model. A hitch cannot compensate for poor loading, worn tires or unsafe driving in crosswinds.
Important: sway control reduces unwanted yaw; it does not make a trailer immune to sway or override safe speed, loading, tire pressure, or towing limits.
06Frequently asked questions
Are Equal-i-zer and CURT TruTrack 4P the same four-point system?
No. Both have four sway-control contact locations, but Equal-i-zer documents socket friction at the head, while CURT describes a spring-and-cam head plus fixed bracket friction in its 4P.
Is every CURT TruTrack a four-point hitch?
No. CURT also sells TruTrack 2P models, which use two bracket friction points and omit the 4P cam system. Check the part number.
Can I use the same spring bars with different rated hitch heads?
Do not assume so. Equal-i-zer documents that spring arms must match the head rating; always use manufacturer-approved matched components.
Should I grease the Equal-i-zer L-brackets to stop noise?
Follow the current Equal-i-zer maintenance guidance. It calls for grease on head socket contact surfaces and says routine grease on L-brackets or spring bars is not necessary. Do not improvise friction-surface lubrication.
Does a 15K weight-distribution hitch let me tow 15,000 pounds?
No. The tow vehicle, receiver, hitch hardware, coupler, trailer and applicable tongue-weight limits all remain controlling; the hitch label alone cannot raise them.
07 Bottom line
Compare Equal-i-zer 4-Point against CURT TruTrack 4P at an appropriate loaded tongue-weight class, then choose between their different head mechanisms and maintenance routines. Verify the CURT model is actually 4P, confirm the full kit contents, and fit the trailer before treating either system as the winner.
