The Complete Guide to Limit Straps
Everything you need to know about protecting your suspension investment.
What Are Limit Straps?
Limit straps are heavy-duty webbing straps that connect your vehicle's frame (or body) to the axle or suspension arm. Their job is simple: prevent the suspension from extending beyond its safe range of travel. When your wheels drop into a hole, go over a jump, or the suspension fully unloads, limit straps catch the droop before something expensive breaks.
Think of them as a seatbelt for your suspension. They don't do anything during normal driving, but when things get extreme, they're the difference between driving home and calling a tow truck.
Why You Need Them
Without limit straps, full suspension droop can cause:
- Shock shafts pulling out of the shock body, destroying the seal and the shock
- CV joints over-extending and tearing boots or snapping axles
- Brake lines stretching and eventually failing
- Sway bar end links bending or breaking
- Bump stop damage from violent rebound after full extension
A quality set of limit straps costs a fraction of a single shock rebuild. For lifted trucks, off-road rigs, and UTVs, they're not optional — they're essential maintenance.
How to Choose the Right Limit Straps
Length
This is the most critical measurement. The strap needs to be long enough to allow full normal suspension travel but short enough to stop extension before components reach their breaking point. Most manufacturers provide sizing guides based on your vehicle and lift height. When in doubt, measure the distance between your mounting points at full droop and subtract 1-2 inches.
Material & Construction
Look for straps made from heavy-duty woven webbing — the same type of material used in tow straps and racing harnesses. Quad-wrapped construction (where the webbing is folded and stitched multiple times) provides the highest strength. Avoid cheap single-layer straps that can stretch or tear under load.
Hardware
Quality mounting hardware matters as much as the strap itself. Look for grade 8 bolts, reinforced mounting tabs, and proper bushings. The strap is only as strong as its weakest mounting point.
Application
Different vehicles need different straps:
- Off-road race vehicles need the highest strength ratings and often require multiple straps per corner
- Lifted trucks and SUVs typically need one strap per side, sized for their specific lift and shock travel
- UTVs need shorter, lighter straps matched to their suspension geometry
Installation Basics
Most limit strap installations follow the same general process:
- Identify mounting points on the frame and axle (or A-arm)
- With the suspension at full droop, measure the distance between mounting points
- Select the correct strap length based on your measurement
- Bolt the strap to both mounting points using the provided hardware
- Cycle the suspension through its full range to verify the strap engages before any component reaches its limit
- Torque all hardware to spec and check after the first few rides
If you're not comfortable doing the installation yourself, any reputable off-road shop can install limit straps in under an hour. It's a straightforward job that doesn't require specialized tools.
Made in USA Matters
Every brand we recommend on this site manufactures their limit straps in the United States. This isn't just about patriotism — it's about quality control. American-made straps use domestically sourced webbing with consistent tensile strength ratings, proper stitching patterns, and quality hardware. When a strap is the only thing between your suspension and a catastrophic failure, you want to know exactly what it's made of and who made it.
