14 Bolt Truss Kit
Serious Strength for the Ultimate Off-Road Axle Build
The 14 Bolt axle is already one of the strongest factory axles out there—but this truss takes it to the next level. Unlike standard I-beam-style trusses that weld only to one side and can warp your housing from uneven heat, our design uses a torsion-box structure. It’s engineered with opposing 180° weld points to minimize distortion and evenly distribute stress across the axle tubes.
Made from precision-bent 3/16" steel plate, this truss kit includes an integrated pinion truss bridge. The bridge features slotted holes to work with or without a pinion guard—no guesswork or risky welding to the cast center section required. This kit gives you maximum strength while keeping weight in check—ideal for serious trail rigs, rock crawlers, or any high-horsepower 14 Bolt build.
Key Features:
- Part Number: R1755
- Material: Bent 3/16" A36 steel plate
- Design: Full-width torsion box truss – opposed welds minimize axle warping
- Includes: Integrated pinion truss bridge with slotted holes (compatible with most pinion guards)
- Fitment: Standard-width 14 Bolt housings; fits most GM full-float axles
- Length: 52.5" end to end
- Notes: Fits axles with unequal-length tubes (e.g., vans or 1988+ 14 Bolts) but may not reach all the way to the flanges
Kit Variations:
- Add Differential Cover: Choose between metric bolts or SAE 3/8" bolts for your 14 Bolt diff cover depending on your axle thread style.
- Add Disc Brake Brackets: Select either SRW (Single Rear Wheel) brackets or C&C (Cab & Chassis) axle brackets to match your swap.
- Add Pinion Guard Hardware: Option to include bolt-on hardware kit for mounting a RuffStuff 14 Bolt Pinion Guard.
Why It Matters:
This is the kind of upgrade that can prevent catastrophic axle failure down the line. By reinforcing the axle tubes evenly and eliminating flex at the pinion, it adds durability where it counts—especially under extreme loads or heavy throttle. The integrated pinion bridge is a smarter, safer alternative to welding directly to the cast housing.
Recommended Add-Ons:
- 14 Bolt Pinion Guard
- 14 Bolt 3/8" Differential Cover (SAE or Metric)
- 14 Bolt Disc Brake Brackets – SRW
- 14 Bolt Disc Brake Brackets – C&C
Engineered, tested, and trusted—this is the truss you want under your rig when the trail turns technical and your foot stays in it.
