When you’re clamping a 3" round axle to 2" wide leaf springs, you need a plate that won’t flex under load. This TruRyde U-bolt plate uses sturdy 0.23" thick zinc-plated steel built to ASTM specifications for dependable strength. It pairs with two 1/2" diameter U-bolts (sold separately) to keep your axle secure and your suspension tracking straight—ideal for 5,200- to 7,000-lb setups that see real road miles.
Moisture, salt, and grime take a toll over time. The plate’s zinc-plated finish guards against corrosion so the metal stays solid even after years of exposure. That means fewer worries about rusted hardware and more confidence that your axle connection will stay tight.
When old plates and bolts seize or corrode, swapping in this plate is simple. Remove the old nuts from your 1/2" U-bolts—or cut them loose if they’re stuck—and slide in the new hardware. The 4" wide plate fits cleanly between the U-bolts, making it a straightforward upgrade that restores a strong clamp between axle and spring.
No guesswork or modification needed—this plate is made specifically to fit 3" diameter round axles and 2" wide leaf springs. It’s the right geometry to seat properly, align your suspension hardware, and keep everything in place whether you’re on pavement or rougher ground.
