Features to know about

Solid Mount for Heavy-Duty Axles: 1/4" Thick Steel Plate Holds 10,000 lbs

When you’re running a 10,000-lb heavy-duty axle, you need hardware that can take the load. This U-bolt plate is built from solid 1/4" thick steel to handle the stress without flexing. It provides a strong connection point between your round, 5" diameter axle and 3" wide leaf springs, keeping everything tight and aligned under weight.

Secure Connection That Stays True: Fits 5" Round Axles with 3" Wide Springs

A loose or shifting suspension setup can throw off your ride and wear out parts faster. This plate works with two 5/8" diameter round U-bolts (sold separately) to clamp the axle firmly to the springs. The fit is dialed in for round, 5" diameter trailer axles and 3" wide leaf springs, giving you a precise and reliable hold where it matters most.

Strong Geometry for Even Clamping: 6" x 9" Plate with 5" and 3" Hole Spacing

Good alignment starts with accurate spacing. This plate measures 6" long by 9" wide with bolt holes spaced 5" apart side-to-side and 3" apart front-to-back (inside to inside). The layout distributes clamping force evenly across the spring pack so the axle stays centered and secure mile after mile.

Built for Long Hauls and Tough Conditions: Heavy-Duty Dexter Compatibility

Made to pair with 10,000-lb heavy-duty Dexter axles, this U-bolt plate stands up to demanding use on loaded trailers. Its sturdy construction resists bending and keeps your suspension tight whether you’re hauling equipment or heading down rough roads.
