Fitment Notes

SPRING LEAVES NOT INCLUDED: The Hellwig 25300 is a mounting hardware kit only. It does not include spring leaves. It must be paired with a compatible Hellwig LP-25 or LP-35 helper spring leaf kit (such as part numbers 2510, 2527, 3511, or 3518) to complete the installation.
FOR 3-INCH WIDE LEAF SPRINGS ONLY: This kit is engineered for vehicles equipped with 3-inch wide rear leaf springs. It is not compatible with 2.5-inch wide leaf springs - use Hellwig mounting kit #25250 for 2.5" spring applications (common on most GM trucks).
Dodge/Ram trucks from 1994 onward typically use 3-inch wide rear leaf springs, making the 25300 the correct mounting kit when pairing an LP-25 or LP-35 spring kit with those vehicles.
Ford F-250 and F-350 Super Duty trucks from 1999-2010 also use 3-inch wide rear leaf springs and require the 25300 mounting kit. For 2011+ Ford Super Duty, use Hellwig mounting kit #25301.
Older Ford F-Series pickups (F-100, F-150, F-250, F-350) and E-Series vans from the listed year ranges also use 3-inch springs and are confirmed compatible with the 25300.
DO NOT USE with factory contact overload springs. If your vehicle has factory contact overload springs, this standard LP mounting kit configuration is not compatible. Consult Hellwig at 1-800-HELLWIG (435-5944) before ordering.
This kit is vehicle-specific in its bracket and U-bolt sizing - it is engineered to allow the LP spring leaves to mount without any modification to the vehicle's leaf spring pack, axle, or frame.
The 25300 is confirmed for Ram 3500 through 2026 per Hellwig's current product page; Ram 2500 is confirmed through 2013. Verify later Ram 2500 fitment with Hellwig directly before ordering.

Features

Vehicle-specific bracket and U-bolt system engineered to mount Hellwig LP-25 and LP-35 helper spring leaves to the factory rear axle and leaf spring pack with no drilling, cutting, or modification.
Includes two heavy-gauge steel axle mounting brackets with durable black powder coat finish - the primary interface between the LP helper spring leaves and the rear axle.
Includes large U-bolts that secure the helper spring leaves to the far (outer) ends of the original leaf springs, medium U-bolts that clamp the leaf assembly together at its center point, and small U-bolts that clamp the mounting brackets to the vehicle's rear axles.
All hardware is zinc-plated for long-term corrosion resistance - critical for underbody components exposed to road salt, water spray, and mud.
3-inch wide spring specification matches the factory leaf spring width on Dodge Ram 1500/2500/3500 (1994-2010), Ram 2500/3500 (2011+), and Ford Super Duty (1999-2010) rear suspensions, ensuring a direct-fit installation without shimming or modification.
Compatible with both LP-25 (2,500 lb. capacity) and LP-35 (3,500 lb. capacity) helper spring leaf kits - one mounting kit design serves the full Load Pro spring lineup.
Simple bolt-on installation using common hand tools - no specialty equipment required.
Manufactured at Hellwig's ISO 9001 and ISO 14001 certified facility in Visalia, California - made in the USA since 1946, backed by Hellwig's Limited Lifetime Warranty.

Product Description

The Hellwig 25300 Load Pro Install Kit is the required mounting hardware package for pairing Hellwig LP-25 and LP-35 helper spring leaf kits with Dodge/Ram trucks, Ford F-Series pickups, Ford E-Series full-size vans, and Ford Bronco models equipped with 3-inch wide rear leaf springs. It cannot be used as a standalone product - the LP spring leaves (such as part #2527 for the LP-25 or #3511 for the LP-35) must also be purchased to complete the installation. Together, the spring leaf kit and the 25300 mounting hardware kit form a complete, bolt-on load management upgrade that adds up to 2,500 lbs. (LP-25) or 3,500 lbs. (LP-35) of supplemental rear load capacity without drilling, cutting, or modifying any factory components.

The 25300 is the 3-inch spring width version of Hellwig's LP mounting hardware family, engineered specifically for the wider leaf springs found on Dodge/Ram 1500/2500/3500 pickups (1994-2026), Ford Super Duty F-250 and F-350 (1999-2010), and a broad range of classic Ford F-Series and E-Series vehicles. It includes two heavy-gauge steel axle mounting brackets finished in black powder coat, plus three sets of zinc-plated U-bolts in three sizes that clamp the helper spring leaves to the outer ends of the factory leaf pack, secure the assembly at its center, and anchor the mounting brackets to the rear axle. Because the kit is vehicle-specific in its bracket geometry and U-bolt sizing, it installs without shimming or adapters, producing a clean, factory-integrated appearance and fit.

The 25300 mounting kit is confirmed compatible with Ram 3500 through 2026 - a key detail for current Ram 3500 owners purchasing LP-25 (part #2527) or LP-35 spring kits. For 2011-2026 Ford Super Duty applications, use mounting kit #25301 instead. For GM 3/4-ton and 1-ton trucks with 2.5-inch wide springs, use mounting kit #25250. Do not use the 25300 on vehicles equipped with factory contact overload springs without first consulting Hellwig. Manufactured at Hellwig's ISO 9001 and ISO 14001 certified facility in Visalia, California and backed by Hellwig's Limited Lifetime Warranty.
