A secure axle connection keeps your suspension working the way it should. This U-bolt plate is built 1/4" thick and designed for 8,000-lb Dexter axles, giving you the strength needed for heavy-duty setups. It’s made to clamp your 3-1/2" diameter round axle tight against the springs so everything stays lined up and stable under load.
Whether your trailer uses 1-3/4" or 2" wide springs, this plate fits right. The holes are set 3-1/2" apart lengthwise and 2" apart crosswise (measured from the closest edges), matching the shape of the axle and spring spacing. That precise layout means your U-bolts slide in easily and pull down evenly for a snug, balanced hold.
When you’re tightening down an axle, the hardware needs to match the muscle of the job. This plate pairs with two 9/16" diameter round U-bolts (sold separately) to secure the axle to the leaf springs. The bolt size gives plenty of clamping force so you can torque everything down confident it’ll stay put mile after mile.
Rough pavement, washboard roads, or heavy cargo can work hardware loose over time. This plate keeps the axle centered and the suspension aligned, preventing twist or shift that can wear parts unevenly. It’s a simple part that does a big job—holding your trailer’s foundation solid so it tracks straight and rides smooth.
