Rite-Hite vs. Blue Giant vs. Kelley: A Buyer's Guide to OEM Dock Leveler Parts
If your facility has been running the same dock leveler for 10+ years, there's a good chance nobody on staff remembers which brand is actually installed. That matters more than most buyers realize: Rite-Hite, Blue Giant, and Kelley all use proprietary hardware, and parts are rarely interchangeable between brands. Ordering the wrong bolt, roller, or bearing means a second shipment and a longer dock closure. Here's what separates the big three.
Rite-Hite
The most widely installed brand in North American distribution centers. Rite-Hite levelers are known for hook-and-lip lip mechanisms, which means wear typically shows up first in the hook key and hinge hardware. Common replacement items include hook keys, carriage bolts, and bearing assemblies for the carriage roller system. If your leveler has a Rite-Hite nameplate, check our Hook Key and Carriage Bolt — both are exact-fit replacements, not generic substitutes.
Blue Giant
Blue Giant equipment (including trailer restraints and mechanical levelers) relies heavily on carriage roller and bearing assemblies for smooth deck travel. These wear gradually, so "the leveler feels rough" is often the first sign before a full failure. Our Blue Giant Bearing & Flange and Carriage Roller are built to original spec, so they don't require re-machining the carriage to fit.
Kelley
Kelley dock parts are typically the small hardware that holds larger assemblies together — washers, flange nuts, and fasteners rated for outdoor/warehouse duty. It's tempting to grab generic hardware-store equivalents here, but Kelley's tolerances and coatings are matched to their leveler frames specifically to resist the vibration and load cycling of daily dock use. Our 1-1/4" Flat Washer and Serrated Flange Nut are Kelley-spec, not aftermarket approximations.
How to identify your brand before you order
Look for a nameplate or stamped logo on the leveler frame, usually near the pit edge or on the lip hinge. No nameplate? Send us a photo of the mechanism and we'll identify the brand and likely part numbers before you place an order — this is the single fastest way to avoid a return.
Why matching brand matters more than matching "size"
Two parts can look identical and still not interchange — thread pitch, plating, and load rating all vary by manufacturer. Buying brand-matched replacement parts is cheaper in the long run than a part that fits loosely and wears out again in six months.
