New Product: XL by JackPucks.com - High Lift Magnetic Jack Puck

[Forager]

This looks unstable for use with a traditional pivoting floor jack. Since the raising arm of the jack swings in an arc as it lifts there is a horizontal thrust placed on the puck. The shorter puck is roughly square (comparing base diameter to overall puck height), whereas this is closer to 2.5:1. I’m sure it’s been tested by the producer, but word of caution to anyone using it to make sure the floor jack moves freely during a lift otherwise that thrust could cause the puck to overturn and drop the load.

This is a solid post, thank you. Those who have used a higher lift jacking tool (OEM, bottle or floor), on a Rivian with it's fully independent front and rear a-arm style suspension has experienced a shifting of the chassis as the vehicle cycles through it's upward suspension travel.

This is true for the factory lifting contraption and the OEM supplied scissors jack, which is worse than a floor jack as it doesn't have the ability to shift when the chassis moves through suspension articulation on upward travel.

Let me explain. When lifting the Rivian on a single point using either the OEM or aftermarket puck, as the vehicles gets higher off the ground the arc of travel on any wheel (shifts inward) as it gets higher, whicn in turn causes the chassis to shift as well.

How does this look in real life? You put your OEM or aftermarket puck in the receiver location on your R1 chassis and begin to lift the corner where the puck is located.

As you lift it higher the suspension begins to raise and the arc in which the suspension travels(inwards) can cause a tilting on the lifting device because the chassis is trying to follow the arc of the suspension. As you get higher the possibility of what the poster says, can cause a greater leaning of the lifting puck (OEM or other) occurs. (as the poster has noted, this shifting and lean is far more noticeable on an XL puck vs. standard puck).

With a high quality floor jack (with casters), you can allow the floor jack to 'follow' the arc and maintain an even lift. If it doesn't follow the arc of the suspension travel, then you need to steer it yourself to maintain a vertical lift. With a Bottle Jack, if you are in a place (say off road) where you need a very high lift (for whatever reason), then you have to position your Bottle Jack in advance to compensate for the chassis shift.

I took three pictures on my R1T to illustrate this.

Photo 1 (vertical, it might not look it, but it is) shows install of the XL with zero load on the jack. You can see the assembly is vertical. As I begin to lift the wheels begin to follow the suspension travel and the chassis moves a bit with it, causing a lean.

Photo 2 (lean) I lifted the right rear to the point where the tire was .50" off the ground and you can see the lean in Photo 2. At that point, I release the bottle jack pressure, but the suspension stays in the same position. Notice bunching up of my vinyl floor mat as the tires are shifting inwards. I used this to illustrate it vs photo 1.

Photo 3 (shifted bottle jack location) I simply re-aligned the jack/puck assembly until it is 90 degrees with the chassis and lifted again. Photo 3. Done and vertical with no lean.

Notes: I have a floor mat on my epoxy floors and as the suspension articulates through it's travel you can hear the tires start to scrub as the shift inwards, which in turn can cause the chassis to slight shift along with it.

Procedure for high lift with a bottle jack.

1. Attach puck and jack assembly so it's vertical.
2. Lift vehicle to the point where tire is just off the ground (lean on jack)
3. Release pressure in bottle jack (suspension stays high on its own).
4. Re-align bottle jack and puck assembly so that it is vertical to the chassis and re-lift (it will be 90 deg.).
5. Complete service of wheel/tire. DONE

I wish we could legislate everything in life to be fool proof, but that isn't possible. The idea behind the XL magnetic puck is to allow someone to get themselves out of a difficult situation and lift the vehicle off the ground at one wheel location in a challenging location, or if they need the additional height.

I find my XL puck a valuable asset for this, but as is the case with any higher lift, it isn't fool proof. Thanks for your post and hope that my response is helpful.

Maybe a dumb question, especially from myself who used to work on a ton of cars (but never having done anything on a larger/higher truck), this seems to have a risk of lateral movement.

If it is up in the air, a small amount of you bumping the truck will topple the entire thing down?

With any higher lift (as detailed substantially in a post above), the lever changes. As noted, this is designed specifically for those that need a higher lift for a wheel/tire repair or change. It may not be suitable for the risk adverse or for an every day tire change, although I wouldn't hesitate personally. We have lower height pucks for this.

If someone is doing an on vehicle repair (as noted as well above), then the wheel never comes off the vehicle, eliminating ALL risk. I pushed on my truck with the tire 1" off the ground multiple times and it was sturdy.

If you are in an off-camber situation it would be more tentative. For an off-roader the option of having a magnetically coupled XL jack puck is worth the trade-off, as evidenced by more than 50 off-road customers who already own our pucks, wanting something like this.

Some customers just want to remove a nail, screw or repair a light cut, while the wheel is still on the vehicle, they just need to get it high enough off the ground to release the air for the repair.

Thanks for your question.

Great, thanks! For me, it would be to swap wheels/tires. Summer/road for off road sets.

Floorjack Recommendations from JackPucks.com​

We recommend either of the Harbor Freight higher lift jacks below for use on your R1 vehicles. If you prefer a higher end brand such as SnapOn those are a great alternative.

1) Harbor Freight Badlands Off Road Floor Jack w/ 29 1/6" of Lift

Badlands HIgh Lift Off Road Floor Jack

2) Harbor Freight High Lift Daytona 3T Floor Jack 24 1/4" Lift

Daytona High Lift Standard 3T Floor Jack 24 1/4"

 

[Mark_AZR1T]

Great, thanks! For me, it would be to swap wheels/tires. Summer/road for off road sets.

For that application go with our standard Magnetic Jack Puck Kit, which we've shipped thousands of to a very enthusiastic customer base. We have plenty in-stock as well in Rivian Yellow or Radiant Red! Thank you so much for your feedback!

2) Harbor Freight High Lift Daytona 3T Floor Jack 24 1/4" Lift

Daytona High Lift Standard 3T Floor Jack 24 1/4"

Can confirm...I bought this one when I found my previous floor jack couldn't lift high enough with a standard puck. This one works well...it's just heavy AF.

You are right!! HF says 100lb's, that might be high, but I had to think about it, when loading in the bed of the R1T! It's heavy!!

 

[pklomboy]

Bought! For the bottle jack you would recommend that big red 10 ton? or will a harbor freight 4 ton work? Thank you

Thank you for your pre-order! While a smaller capacity bottle jack will work, it also means the top hat on the bottle jack will have a smaller diameter. This will fit in our deep bottle jack port, but it will have some slack.

We designed the diameter of our port around the Big Red 10T bottle jack for four reasons. 1. Readily available via Amazon. 2. Affordable. 3. Large 10T Capacity 4. Lift Height.

The 10T capacity makes it a breeze to lift the 7000lb R1 and at $35.99, it's a great solution. If you already have the 4T unit, then wait until you receive your XL puck and see how it goes...no harm in that.
