Bull Strap Limit Strap Clevis — Heat-Treated 4130 Chromoly, Made in USA

A limit strap is only as strong as the hardware connecting it to your suspension. Bull Strap's limit strap clevis is built from heat-treated 4130 chromoly steel — the same material used in high-performance roll cages, chassis tubing, and aircraft components — and load-tested to over 14,400 lb before release. This is the clevis that goes on every Bull Strap limit strap build, designed to handle the shock loads and repeated stress that off-road suspension systems generate at speed.

Bull Strap manufactures one clevis design that accommodates single, double, and triple limit strap configurations. You don't have to guess how many straps you'll run and buy a different clevis for each setup. The hardware package includes all sleeves and bolts for one, two, or three straps — because suspension setups change, builds evolve, and you shouldn't have to rebuy hardware every time you add a strap.

Why 4130 Chromoly — And Why Heat Treatment Matters

4130 chromoly (chromium-molybdenum steel) is a high-strength alloy steel widely used in aerospace, motorsport, and military applications. The "4130" designation refers to its AISI steel classification — approximately 0.30% carbon content with chromium and molybdenum alloying elements that dramatically increase tensile strength, fatigue resistance, and toughness compared to mild steel.

Heat treatment is what transforms 4130 chromoly from a good material into an exceptional one. The heat treatment process — typically normalizing or quenching and tempering — relieves internal stresses from the forging process, refines the grain structure, and achieves tensile strengths well above the untreated baseline. Bull Strap's clevis hardware is heat-treated after machining, not before — meaning the final dimensions and hole placements are accurate and the material is in its strongest state when the part ships.

The practical result: Bull Strap's clevis hardware has been load-tested to over 14,400 lb without failure. That load figure isn't a paper rating — it's from actual destructive testing. For context, the bolt holes are sized at 9/16" to match Bull Strap's limit strap hardware standard, and the entire assembly is designed to fail the strap webbing before the clevis — meaning the weakest link by design is the replaceable webbing, not the hardware.

Silver vs. Black — Finish Differences

Bull Strap's limit strap clevis is available in two finishes:

• Silver (Natural / Clear Coated) — $39.99. Natural 4130 chromoly finish with protective clear coat. Shows the raw material appearance. Slightly lighter visual profile on the suspension.


• Black (Powdercoated) — $44.99. Matte black powdercoat finish over heat-treated 4130 chromoly. More corrosion-resistant in wet and muddy environments. Visually stealth on dark suspension components.

Both finishes use the same heat-treated 4130 chromoly base material with identical load ratings and all-inclusive hardware packages. The choice is aesthetic and corrosion-preference based.

What's Included in the Hardware Package

Bull Strap designs the clevis package so you never have to make a separate hardware run. Each clevis ships with:

• The clevis body — heat-treated 4130 chromoly in your chosen finish


• All sleeves for single, double, or triple strap configuration


• All bolts and fasteners needed for installation


• No additional hardware required for any configuration

This all-in-one approach is intentional. Bull Strap's position is straightforward: if you're building a limit strap setup, you shouldn't be making multiple orders to assemble complete hardware. The clevis ships ready to install with any combination of Bull Strap limit straps from 6" to 44".

What Vehicles and Applications Is This Clevis Compatible With?

The Bull Strap limit strap clevis is designed to work with standard limit strap mounting points across all major off-road vehicle platforms. Compatible applications include:

• Jeep Wrangler JK/JKU — 2007–2018, both solid axle suspension setups


• Jeep Wrangler JL/JLU — 2018–present, factory and aftermarket lifted builds


• Jeep Gladiator JT — 2020–present


• Ford Bronco — 2021–present, including Sasquatch package builds


• Toyota Tacoma — 2nd and 3rd gen long-travel front and rear suspension builds


• Can-Am Maverick X3 — all variants, factory and extended-travel setups


• Polaris RZR XP 1000, XP Turbo, Pro XP, Pro R — all current-generation UTVs


• Custom prerunner trucks — any build with standard limit strap tab mounting


• Desert race vehicles — long-travel builds requiring redundant strap configurations

The 9/16" bolt hole diameter is the industry standard for limit strap mounting hardware. If your vehicle has a non-standard bolt hole size, contact Bull Strap before ordering — custom hole sizes are available on request for fabricated one-off applications.

How to Set Up a Single, Double, or Triple Limit Strap Configuration

The clevis hardware accommodates all three configurations. Here's how each setup differs and when to use each:

Single Strap Per Corner

The most common setup for street-driven lifted vehicles and moderate off-road use. One limit strap per corner provides suspension travel protection with minimal weight penalty. Ideal for Jeep Wrangler JL and JK daily drivers with 2"–4" lifts. Install: one Bull Strap limit strap through the clevis body with the appropriate sleeves installed for single-strap use.

Double Strap Per Corner

Standard for dedicated off-road vehicles, desert trail rigs, and light race applications. Two straps per corner provides redundancy — if one strap fails (rare with Bull Strap hardware, but possible from rock damage or cut webbing), the second strap catches the axle. Install: two limit straps through the clevis using the double-strap sleeve package included in the hardware kit.

Triple Strap Per Corner

For high-speed desert racing and extreme long-travel applications where strap loads are highest and failure consequences are most severe. Triple strap configurations are most common on prerunner trucks, Class 1/1600 off-road race vehicles, and Can-Am X3 race builds. The clevis hardware accommodates all three straps without modification or additional parts.

Race-Proven Performance — 15+ Years on the Course

Bull Strap is the largest manufacturer of suspension limit straps in the world, and the clevis hardware has been used in best-in-class off-road racing for over 15 years. The 14,400 lb load test rating isn't a factory specification — it's a result of destructive testing on production hardware. Race conditions generate shock loads that dwarf static measurements, and the Bull Strap clevis has been proven in those conditions repeatedly.

When you're running desert whoops at speed or dropping off ledges on a technical rock crawl course, the hardware connecting your limit strap to your chassis is seeing impacts far above any rated load. That's why heat-treated 4130 chromoly matters — the fatigue resistance and toughness of the alloy under repeated shock loading is what separates it from hardware that works fine in a static pull test but cracks at the third hard landing.

Frequently Asked Questions — Limit Strap Clevis

Does this clevis work with any brand of limit strap, or only Bull Strap straps?

The clevis uses standard 9/16" bolt holes and is compatible with any limit strap that matches that hardware dimension. However, Bull Strap strongly recommends pairing the clevis with Bull Strap limit straps for a tested, known-strength assembly. Third-party straps may have different webbing ratings and hardware compatibility — verify before mixing brands in a critical suspension application.

Do I need two clevis units per vehicle — one for each side?

Yes. Each clevis is a single-side unit. A complete vehicle build requires two clevis units — one for the driver's side and one for the passenger's side — at each axle where limit straps are installed. Many builders run straps on both front and rear axles, requiring four total clevis units.

Is the clevis adjustable after installation?

The clevis is adjustable at the limit strap mounting points — you can slide the strap through the clevis body to adjust effective strap length slightly during installation. For significant length adjustment, the correct approach is to order a different strap length, not to compensate with the clevis.

What torque spec should I use for the clevis mounting bolts?

Torque spec depends on the bolt size and thread pitch matching your vehicle's limit strap mounting tabs. Consult your vehicle-specific suspension manufacturer's specifications for limit strap hardware torque values. Standard practice for suspension hardware in this size range is 35–45 ft-lb with thread lock compound on the bolt threads.

Can this clevis be used on a military vehicle?

Bull Strap limit strap hardware is Berry Amendment compliant, manufactured in the USA using domestic materials. The limit strap clevis and all hardware are approved for use on military vehicle applications that require domestic-source components.

How the Clevis Fits Into a Complete Limit Strap System

A complete suspension limit strap setup on any off-road vehicle requires three elements working together: the limit strap itself, the clevis hardware, and the mounting tabs on your vehicle. The clevis is the critical link between the strap and the chassis — it's the piece that absorbs the shock load transfer when the axle hits full droop and the strap engages.

Most off-road vehicles and lifted trucks come with limit strap mounting tabs already welded to the chassis and axle housing. These tabs accept a bolt through the clevis's bolt hole, securing the clevis to the mount point. The limit strap threads through the clevis body, creating a loop that engages when the axle travels to the end of its designed range of motion. When the strap catches the axle, all of that force transfers through the clevis hardware and into the chassis — which is exactly why the clevis must be stronger than the strap.

Bull Strap designs the clevis to be the strongest link in the chain, not the weakest. The 4130 chromoly steel and heat treatment process ensure the clevis hardware consistently outperforms the webbing in destructive testing. When a limit strap system fails in the field, it should fail at the webbing — a replaceable $25 strap — not at the hardware, which requires disassembly of the entire mount to replace.

Bull Strap — Largest Suspension Limiting Strap Manufacturer in the World

Bull Strap is a division of Bartact (Trek Armor Inc.), based in Temecula, California. As the world's largest manufacturer of suspension limit straps, Bull Strap produces every component of the limit strap system in the USA: the webbing, the hardware, the clevis, and the finished strap assembly. The clevis hardware is not sourced from an overseas supplier and branded — it's designed, specified, and manufactured under Bull Strap's direct quality control.

The company has been producing limit strap hardware for over 15 years and has supplied best-in-class off-road racing teams throughout that period. Every design decision in the clevis — the 4130 chromoly alloy selection, the heat treatment specification, the all-inclusive hardware package, the multi-strap compatibility — comes from 15 years of field feedback from racers running these parts at the limit of suspension performance.

If you are building a limit strap system from scratch, the correct order is: (1) measure your droop distance and order the appropriate Bull Strap limit strap length, (2) order the clevis hardware to match your chassis and axle tab configuration, (3) install with proper torque and thread lock. Bull Strap's team can advise on any step of this process — contact them directly with your vehicle, lift height, suspension brand, and intended use before ordering if you have questions about sizing or configuration.
