Bartact's suspension limit straps represent the same race-proven engineering found in the Bull Strap lineup, under the Bartact brand name. Both product lines are manufactured by Trek Armor Inc. in Temecula, California — the same factory, the same materials, the same quad-wrap construction, and the same heat-treated 4130 chromoly hardware. If you've been shopping Bartact accessories and want limit straps that match the Bartact standard of Made-in-USA quality and mil-spec materials, this is the product.
Bartact has been a trusted name in off-road accessories for Jeep, Bronco, and truck platforms for over a decade. The limit strap lineup extends that same quality standard into suspension protection hardware — a category where materials and build quality directly determine whether your axle or your strap takes the load when suspension reaches full droop.
Most limit straps on the market use one or two layers of webbing. Bartact uses four. The difference isn't academic — it's the difference between a product that's designed around cost reduction and one that's designed around performance at the limit of suspension travel.
Here's what the quad wrap means in practice: each Bartact limit strap is constructed from four full layers of 1-3/4" mil-spec, resin-coated, twisted-yarn nylon webbing, each layer rated at 7,000 lb. Total webbing strength: 28,000 lb. More importantly, the webbing wraps completely around each end piece twice — two full layers of webbing contact at each buckle. This eliminates the single-point webbing failure mode that plagues single-layer straps, where the webbing tears at the hardware contact point under repeated shock loading.
The resin coating on the nylon webbing isn't cosmetic. MIL-W-27265 Type 13R resin treatment adds abrasion resistance, moisture resistance, and chemical resistance to the webbing. When you're crawling through mud, crossing water, or dragging against rocks, the resin coating is what keeps the webbing from degrading over time. Untreated nylon absorbs water, weakens under UV exposure, and abrades faster. Resin-treated nylon rated to military specification does none of those things on any meaningful timeline.
The webbing is only half the equation. The end hardware is where most cheap limit straps fail — not because the webbing tears, but because the buckle hardware cracks or deforms under shock loading. Bartact uses enamel-coated, heat-treated 4130 chromoly end pieces with 9/16" bolt holes and protective deflector sleeves around the webbing contact point.
Here are the actual numbers: Bartact's 4130 chromoly buckles are rated for 12,500 lb and consistently test above 15,000 lb before failure. Counterfeit straps in the market copy the "4130 Heat Treated" marking but use inferior alloy or untreated hardware — those end pieces test to failure at approximately 5,500 lb. That's a 3x strength difference at the most critical component in the assembly.
The enamel coating on Bartact's hardware is a deliberate choice over the older zinc-plating standard. Zinc plating scratches off under flexing and impact — enamel coating bonds to the surface and maintains its protective layer through repeated stress cycles. In a suspension application where the hardware flexes and impacts thousands of times per mile of off-road terrain, coating durability translates directly to hardware longevity.
Bartact's limit straps are Berry Amendment compliant. The Berry Amendment (10 U.S.C. § 2533a) requires that certain items procured by the Department of Defense be manufactured in the United States using American materials. Berry compliance on a limit strap means every component — the nylon webbing, the chromoly hardware, the thread, the coating — is sourced and manufactured domestically.
For civilian off-road builders, Berry compliance is a meaningful quality signal. It means the manufacturer can't substitute cheap overseas components without losing compliance certification. It means the supply chain is auditable and the materials are known. For military contractors and government vehicle operators, it's a procurement requirement. Bartact's limit straps are approved for use on military vehicles including the General Motors ISV (Infantry Squad Vehicle) precisely because of this compliance.
The practical benefit for civilian buyers: you can be certain that what's in the strap matches what's on the label. No undisclosed material substitutions, no Chinese hardware with American brand markings, no webbing that's rated to a different standard than stated.
Bartact limit straps are built to universal mounting dimensions — 9/16" bolt holes, standard end piece geometry — and fit limit strap mounting tabs across all major off-road platforms. Confirmed compatible applications:
Available in 39 standard sizes from 6" to 25" (the full range up to 44" is available) in 1-inch increments, with half-inch custom sizes available on request. Length is measured center-of-hole to center-of-hole. For nylon stretch: plan for approximately 1 inch of stretch per foot of strap length under normal load. Stretch varies with weight, temperature, and wet conditions.
Choosing the wrong length limit strap is the most common installation mistake. Too short and the strap pre-loads the axle before full droop is reached, defeating the purpose and adding stress to your control arm bushings. Too long and the strap provides no protection — the axle can travel beyond safe range before the strap engages.
The correct measurement process:
If you're not confident in your measurement, contact Bartact or Bull Strap directly with your vehicle, lift height, and suspension brand — they've built straps for every common application and can advise on the correct length.
Bartact limit straps install at the existing limit strap mounting tabs present on most off-road vehicles and lifted builds. Standard installation requires:
No cutting, drilling, or modification to the vehicle is required in most applications. The 9/16" bolt holes in the end hardware fit standard limit strap tabs on all compatible vehicles listed above. Torque the mounting hardware to the specification for your vehicle's limit strap tabs — consult your suspension manufacturer's instructions. Apply thread lock to all fasteners to prevent vibration loosening on the trail.
Yes. Bartact and Bull Strap are both product lines of Trek Armor Inc., manufactured in the same facility in Temecula, California. The limit straps carry the same specifications, materials, and hardware regardless of which brand name appears on the product. The product lines exist for historical and distribution reasons — the performance is identical.
The quad-wrap webbing assembly provides 28,000 lb of total webbing strength. The 4130 chromoly end hardware is rated for 12,500 lb and has tested to over 15,000 lb before failure in destructive testing. Practical load capacity in suspension applications is a function of the clevis hardware and mounting tabs on the vehicle — the strap itself is not the limiting factor in a properly built installation.
Most installations use the Bull Strap limit strap clevis (sold separately) to connect the strap to the vehicle's chassis and axle mounting tabs. Some aftermarket suspension kits include integrated limit strap tabs that accept the strap's end hardware directly — verify your specific suspension kit's mounting design before ordering. The clevis is the correct hardware for most OEM and aftermarket tab configurations.
Inspect limit straps after any hard suspension impact, off-road race, or suspected strap engagement during rock crawling. Replace immediately if you see: webbing fraying or cuts, visible distortion of the end hardware, cracked or bent buckle hardware, or any strap that has taken a known over-load impact. With Bull Strap's quad-wrap construction and 4130 chromoly hardware, replacement due to normal wear is uncommon — but inspect regularly in active off-road use.
Yes. Bartact and Bull Strap limit straps are race-proven across Best in the Desert, SCORE International, and BITD off-road racing circuits. They have been used by best-in-class competitors for over 15 years. Check with your specific series' rulebook for any restrictions on suspension component specifications — the straps themselves are not restricted by any major series we're aware of.
We DON'T SKIMP on quality...EVER! Made from 4 Layers of 7,000 LB MIL-W 27265 Type 13R berry compliant webbing (28,000 lb strength total (load limit due to thread stress is approximately 14,500 lb breaking strength) with heavy duty enamel-coated Heat-Treated 4130 Chromoly hardware with deflector plates for added webbing support, and high grade nylon thread, Bull Strap Limit Straps are made to last and to hold up much better than flimsy single or double layer straps that have hardware not even half the strength. BEWARE! Other Made in China straps have copied our stamp with the '4130 Heat Treated', but those end pieces break at roughly 5,500 lbs. Ours buckles are rated for over 12,500 lbs, but consistently hold up to over 15,000 lbs in testing before breaking.
*WHEN ORDERING, LENGTH OF STRAP IS DISTANCE BETWEEN CENTER OF HOLE TO CENTER OF HOLE. NYLON IS MEANT TO STRETCH SLIGHTLY TO KEEP A SMOOTHER TRANSITION. STRAP STRETCH DEPENDS ON MULTIPLE VARIABLES, INCLUDING WEIGHT, WET CONDITIONS, ETC, BUT ON MOST APPLICATIONS, YOU SHOULD FACTOR ROUGHLY AN INCH OF STRETCH FOR EVERY FOOT OF STRAP.
