GENESIS JACK™ | 2.0

Name: GENESIS JACK™ | 2.0
Brand: Kleva Built
Rating: 4.53 (17 reviews)

The GENESIS JACK™ | 2.0 is Kleva Built’s space-saving deadlift jack: a laser-cut 6061 aluminum lever, under 2 lbs, that lifts one loaded barbell sleeve at a time so plates seat all the way into the collar – an alternative to a full-size double-jack or a change plate/dead wedge for lifters short on space. It’s a revision of the original Genesis Jack rather than a new design: the 2.0 adds UHMW plastic grip inserts to the handle and molded plastic to the feet, answering the two most common complaints about the 1.0 (a bare, hard-to-grip handle and metal feet that could mark flooring).

Acetal receiver hooks protect the barbell’s knurling and ABS plastic feet protect the platform underneath; it’s built around bars up to 30mm in diameter and competition-diameter (450mm OD) plates, ships fully assembled, and is hand-assembled in Arizona. As a single-sided jack it has a placement learning curve and gives up some side-to-side stability compared to a full-size double-jack, and the plastic feet can slip or dig into wooden platforms under heavy loads. Kleva Built sells it directly and licenses a co-branded version through REP Fitness; both share the same physical design.

What is a Miscellaneou?

What’s in Miscellaneous

This is the catch-all for the conditioning tools and accessories that don’t fit a single equipment class — weighted vests and plate carriers, medicine and slam balls, plyo boxes, ab mats, and the odds and ends that round out a garage gym. Items land here because their job (loaded carries, jumps, core work) cuts across the categories rather than sitting neatly inside one.

Who it’s for

Anyone filling in the gaps around the big pieces. If you already have a rack, bar, and plates, this is where you find the vest for rucking and weighted push-ups, the ball for slams and wall throws, or the box for step-ups and box jumps. Match the tool to the training you actually do — a plate carrier for conditioning and rucking, plyo boxes for explosive work — rather than buying the whole shelf.

Reviews by source

Expert	4.53/5	17 reviews
Youtube	4.7/5	3 reviews	Basement Brandon, Garage Gym Gainz, and Red Beard Lifts all verdict positively -- lightweight, portable, faster/tidier loading than a full-size jack -- with only minor caveats (plate-size preference, plastic feet slipping/digging into wood platforms at high weight).
Reddit	4.2/5	6 reviews	r/homegym sentiment is strongly positive -- multiple owners call it one of the best recent gym-gear buys and say they replaced a full-size jack with it -- tempered by one substantive dissent citing bar-fit pickiness (power/specialty bars don't seat) and plastic degradation.

The Genesis Jack 2.0 is the space-saving answer to a full-size deadlift jack: a laser-cut aluminum lever that weighs under two pounds, lives in a gym bag or on a plate-tree bracket, and picks up one loaded sleeve at a time so plates seat all the way into the collar. Functionality and build quality are the standouts — GymRadar owners rate Build Quality 4.71/5, its highest dimension, and Gray Matter Lifting calls it “the cleanest and best functioning deadlift jack on the market.” Value is the clear weak spot, and every source agrees: GymRadar’s Value score (4.35/5) is its lowest, Garage Gym Experiment files it under “extras” rather than foundation gear, and Gray Matter Lifting flatly calls it the most expensive deadlift jack ever made — with listed prices ranging from about $80 to $110 depending on where and when you buy, and the Kleva Built store frequently sold out. It is best understood as home-gym-grade: two GymRadar owners independently report a unit that broke in half under commercial-gym traffic. If budget matters more than footprint, The Dead Wedge does a cruder version of the same job for a fraction of the money; if you have a dedicated platform and the floor space, the full-size Genesis Jack Pro or a Rogue Mini Deadlift Bar Jack are the natural step-ups. Note that a co-branded REP x Kleva Built version of the same design is sold separately and has historically listed cheaper.

+Functionality: the angled fulcrum lifts the entire loaded sleeve clear of the floor, so plates always push fully into the collar — faster and tidier than a change plate or wedge (Basement Brandon, Garage Gym Gainz)
+Versatility: under 2 lbs and gym-bag portable; GymRadar owners store it on a Rogue plate-tree bracket and use it in single-car garages where a full-size jack will not fit
+Build quality: laser-cut 6061 aluminum with plastic liners protecting both the bar knurling and the floor; Build Quality is the top-scoring dimension on GymRadar at 4.71/5
+Durability: Gray Matter Lifting reports his unit in excellent condition after multiple years of use, and Basement Brandon saw no flooring damage after two years
+Functionality: capacity is real for home use — Garage Gym Experiment loaded 425 lbs per side without issue, and puts the time saved at over five hours a year for a twice-weekly deadlifter

−Value: the weakest dimension in every source — GymRadar's Value score (4.35/5) is its lowest, Gray Matter Lifting calls it the most expensive deadlift jack ever made, and Garage Gym Experiment says $99 is a hard price to swallow while still building a gym
−Durability: two independent GymRadar owners (both rating it 3.33) report a unit found broken in half in a commercial gym — treat this as home-gym-grade, not commercial-grade
−Functionality: the 30mm hook opening is a genuine fit caveat; an r/homegym owner reports it really only likes thin deadlift bars, that a power bar is a tight fit, and that specialty bars will not work at all
−Build quality: the ridged plastic feet can dent softer wooden platforms under heavy load — raised independently by Gray Matter Lifting, an r/homegym owner, and Red Beard Lifts, who also found the plastic slippery on bare plywood
−Versatility: it is a single-sided jack with a placement learning curve (roughly an inch of clearance from the collars) and it is awkward to use when deadlifting inside a power rack (GymRadar owners, Gray Matter Lifting)
