Farm Jack Mount for Roof Rack: Worth It, or Just Extra Roof Weight?
Short answer: Yes, if you actually carry a farm jack (high-lift jack) for off-road recovery and are currently wedging it loose in the cargo area or trunk. A dedicated roof mount keeps it secured, out of the way, and immediately accessible when you need it. Skip it if you don’t own a farm jack, or if your roof load budget is already tight with a cargo box or rooftop tent — a farm jack is genuinely heavy, and it’s worth doing the weight math first.

How we evaluated this mount
We have not installed this exact mount ourselves. This assessment is built from the listing’s stated design and compatibility, how clamp-on farm jack mounts perform as a product category, and the roof-weight math we’ve already worked through in detail for RackReveal’s own crossbar capacity research (linked below). The early rating (around 4.5/5) is from a small number of reviews since this is a newer listing — treat that as an early positive signal, not a large-sample guarantee, and check the current review count on the listing yourself before buying.
Specs and quick verdict
| Attribute | Detail | What it means for you |
|---|---|---|
| Quantity | 2 mounts (1 pair) | The standard setup needed to secure one farm jack top and bottom |
| Installation | Clamp-on, no-drill | No permanent holes; recheck clamp tension periodically |
| Fitment | Round/square crossbars, stated size range | Measure your crossbar’s cross-section before ordering — not universal |
| Added weight | Jack itself ~20-25 lb + mount hardware | Counts fully against your roof’s weight budget — see the section below |
| Best for | Off-roaders/overlanders who already own a farm jack | Not useful if you don’t carry one |
| Price | Check listing (fluctuates) | — |
The weight math you should do before mounting a jack on your roof
A farm jack typically weighs somewhere around 20-25 lb on its own, before the mount hardware. That’s a meaningful chunk of most vehicles’ roof budget, which is usually only about 150-165 lb dynamic (moving) load according to the owner’s manual — not the crossbar’s own, often much higher, rating. We covered this in detail in our own 251-listing roof rack weight capacity analysis: the crossbar number on the box is rarely your real limit, your vehicle’s roof rating is. If you’re already running a cargo box or rooftop tent, add the jack’s weight to that total before assuming there’s room — this is exactly the kind of accessory that can push a loaded rack over budget without anyone doing the math first.
Clamp-on vs. bolted: what “secure” actually means here
A properly torqued clamp mount holds a farm jack securely for normal driving and moderate off-road use — it is not a weak connection. But it is fundamentally a friction/clamp connection rather than a through-bolted one, so the same rule applies as any clamp-mounted roof accessory: recheck the tension periodically, especially after washboard roads or rough terrain that can work a clamp loose over time. Don’t treat “installed once” as “done forever.”
Who this is NOT for
- Anyone who doesn’t own a farm jack. This mount has exactly one job — it’s not a general recovery-gear rack.
- Vehicles already near their roof weight budget. Do the math (crossbar rating AND vehicle roof rating) before adding a ~20-25 lb jack to an already-loaded rack.
- Non-standard crossbar profiles. Aero-shaped or unusually thin bars may not fit the clamp’s stated size range — measure first.
- Buyers wanting a multi-tool bracket. This mount is shaped for a farm jack’s body specifically; a shovel or axe needs a different bracket.
Frequently asked questions
Will a farm jack mount fit any roof rack crossbar?
Only crossbars within the clamp’s stated size range — round or square tube of a compatible diameter/width. Aero or very thin bars may not fit. Measure your crossbar’s cross-section first.
Does mounting a farm jack on the roof affect my roof’s weight rating?
Yes, significantly — a farm jack runs roughly 20-25 lb, a meaningful share of most vehicles’ ~150-165 lb dynamic roof rating. Factor it in before adding a cargo box or tent to the same rack.
Is a clamp-on mount as secure as bolting the jack down?
Secure for normal and moderate off-road driving when properly torqued, but it’s a friction connection, not through-bolted. Recheck tension periodically, especially after rough terrain.
Can I mount other tools using the same bracket, not just a farm jack?
No — it’s shaped around a farm jack’s flat steel body. A shovel, axe, or other tool needs its own bracket made for that shape.
Does it come as a pair, and do I need both for one jack?
Yes, it’s sold as 2 mounts, which is the standard setup — one near the top and one near the bottom of the jack — to keep it from pivoting or rattling. A single mount would under-support one jack.
