JACKPOINT JACKSTANDS

Technical Specifications:

 

Material - Jackpoint Jackstands are cast with Almag 535.  Almag is a magnesium/aluminum alloy that was chosen for its greater load capacity and elasticity when compared to some less expensive aluminum alloys like 356 T6 or 319. 

 


Load Rating
– Jackpoint Jackstands are rated at 4000 pounds.  The industry standard for jack stand load rating is to rate jack stands in pairs.  Jackpoint Jackstands are rated to satisfy ANSI standards.  According to ANSI standards, a single jack stand from a pair must support one and one half times the total rated load for the pair.  That means a single jack stand for a pair rated at 4000 pounds must support 6000 pounds.  Jackpoint Jackstands have been physically tested to meet or exceed the ANSI standard.

 


Design Features
- One unique design feature of the Jackpoint Jackstand is the open front.  This feature allows the jack stand to fit around floor jacks while the jack is supporting a vehicle.  To compensate for this opening, Jackpoint Jackstands use varying wall thicknesses to evenly distribute load throughout the jack stand base and eliminate stress hot spots.

 

Another unique feature is the contoured, interlocking pad and base design.  The bottom of the pad is angled to match a parallel angle in the top of the base.  These parallel angled surfaces help align and center the base under the pad as the pad is lowered on to the base.  Simultaneously, the same pad and based surfaces are contoured with matching surfaces that lock the pad in place once it is resting on the base.  The load on the pad actually makes the pad more secure on the base creating a unified, secure structure to support the vehicle.  The underside of the Jackpoint pad is recessed so that it won’t slide off the top of the jack plate as the vehicle is being jacked (jack plate should be 3.5 inches to 5 inches in diameter).

 

Also unique to the Jackpoint Jackstand is the top surface of the pad which is designed to match the jacking location on the specific vehicle.  Some vehicle manufacturers use reinforced pinch welds on the unibody chassis to create the factory jacking location.  Other manufacturers use a flat surface with a hole or other recessed point in the flat surface as the jacking location.  The basic Jackpoint Jackstand pads are designed to accomodate these common, but different jacking configurations.  The standard pad is cast with a "V" channel to accept the pinch weld type jacking location common to many vehicles.  The desired use of this channel allows the vehicle pinch weld to rest in the channel while the car is supported on the reinforced section of the chassis.   Different factory jacking locations are matched to different Jackpoint Jackstand pads.  Custom pads can be machined for speciality cars that have unusual jacking configurations.  All of these various pads can be used with the same Jackpoint base to provide secure support for most cars.

 

Jackpoint Jackstands are stackable.  The Jackpoint stand is wider than most standard jack stands, however they require no more surface area for storage because they can be stacked four or more stands high.  While stacked, the Jackpoint Jackstands can be placed on a Jackpoint dolly for easy movement around the garage.

 


Dimensions
- Jackpoint Jackstands are 13 inches high (12.25 inches with the low profile pad), 16 inches wide, and 12 inches deep overall.  This provides a wide and deep base that is stable and prevents tipping.  Though shorter than some jack stands, Jackpoint Jackstands provide greater ground clearance when used in pairs because they support the vehicle at a location that takes advantage of geometry when the front or the back of the vehicle is supported. 

 


Working Height
- Working height or ground clearance of a vehicle placed on Jackpoint Jackstands will vary based on a number of factors.  First, the working height will be higher for either end of the vehicle when the jack stands are used in pairs at the front or rear jacking locations of a vehicle than when four stands are used together.  Second, working height when working in pairs will be higher on vehicles with shorter wheel bases than longer wheel base vehicles.  Third, working height will be higher when the jack stands are used in pairs as the jacking location on the vehicle gets closer to the center of the vehicle.  ALWAYS USE THE FACTORY JACKING LOCATION.

 

For most vehicles, the minimum working height for the vehicle's chassis will be 13 inches using the Standard "V" channel Pad and 12.25 inches using the Low Profile Pad.  That may result in a lower working height for components that center of the chassis if two stands are being used.  Some vehicles, like sport utility vehicles or full size sedans may have combined ride heights and suspension travel that will allow the tires to still contact the ground with the Jackpoint Jackstand in place.  This is more likely to occur when four jack stands are used than two.  It should be noted that industry standard for jack stand usage suggests jack stands be used in pairs, leaving two wheels on the ground.   Properly located, Jackpoint Jackstands provide greater working height and maximum stability when used according to induutry standard and that is the recommended application for best results.  With two Jackpoint Jackstands in place, working height at the lifted end of the vehicle will range from  15 to 23 inches.

 

Critical Dimensions - for floor jack clearance are:

  • Jack's plate – 3.5 -5 inches in diameter
  • Widest part of jack lifting arm - 5.5 inches
  • Widest part of jack's wheels, roller, or handles at the front of the jack or back 10 inches from the front of the jack - 11.6 inches.         

 

Jackpoint Jackstand Components:

 

  • Base - the main support component has been designed to meet ANSI standards for jack stands rated at 4000 pounds.  THE BASE SHOULD ONLY BE USED IN CONJUNCTION WITH A JACKPOINT PAD THAT IS COMPATABLE WITH THE JACKING LOCATION OF THE PARTICULAR VEHICLE BEING SUPPORTED.  THE BASE IS NOT DESIGNED TO BE USED WITHOUT THE PAD AND SERIOUS INJURY OR DAMAGE MAY OCCUR IF USE WITHOUT THE PAD IS ATTEMPTED.
  • Pad - the Jackpoint Pad is designed to interlock with the Base and the vehicle's manufacturer's jacking location.  Different jacking location configurations may require different Pads.  It is important to confirm the jacking location on the vehicle is compatible with the Pad.  Most vehicles will work with one of the standard Jackpoint Pads.  Special vehicles may require a customized Pad.  The following is a partial list of vehicles that work with one of the available Jackpoint Pads.  THIS LIST ASSUMES THE JACKING LOCATION ON THE VEHICLE IS IN UNDAMAGED CONDITION.  Vehicles that have been lowered or modified may require a different Pad. 

Examples of Vehicles using the standard height "V" channel Pad:

            Chevrolet (except C5 and later Corvette), Ford, Nissan (except GTR), Mitsubishi, Pontiac, Subaru, Saturn, Scion, Toyota, Dodge (except Viper).  Note: C4 Corvettes may require a custom pad to protect a gas line located near the left rear jacking location.

 

Examples of Vehicles using the Low Profile Pad:

            Porsche, BMW, Corvette, Viper, Nissan GTR.

 

Examples of Vehicles that may require custom Pad:

            Mercedes SL, C4 Corvette, Bentley, Lamborghini,

 

  • Locating Pin - the locating pin is used for vehicles with a flat jacking surface as opposed to a pinch weld.  The pin is removable and can be replaced if it is damaged during use.  The pin is made of 6061 aluminum which is fairly soft.  The purpose for selecting this material was to allow the pin to be damaged instead of the pad or vehicle if the pin isn't properly aligned with the hole in the vehicles jacking location.  If the pin becomes damaged, it should be replaced.
  • Pad insulator - Jackpoint Jackstands come with a urethane rubber insulator.  The insulator is designed to insulate the vehicle from metal to metal contact between the pad and the vehicle when the stands are in use.  However, the insulator also provides greater friction and reduces slippage compared to metal to metal surface contact.  It is, therefore, a part of the Jackpoint Jackstand that improves the secure structure for supporting the vehicle.  The insulator will wear out with use and may tear when used on certain types of vehicles.  This is normal and the insulator should be replaced when it becomes worn or damaged.
