The Artec 14 Bolt Modular Truss braces the GM 14-bolt 10.5" full-float rear axle — the workhorse one-ton swap under Chevy/GMC 2500 and 3500 trucks from 1973 to 2019 — while leaving your suspension options open. A 3/8" steel top plate and interlocked 1/4" gussets weld around the housing to kill axle wrap and tube flex, and the modular layout clears factory leaf perches, accepts add-on coil or leaf perches, and even fits ribbed-casting housings. When you are ready to link the rear, the flat top puts upper-link joints about 8" off the axle centerline.
Features
- 3/8" steel truss top with interlocked 1/4" steel gussets
- Modular, self-jigging construction for accurate, straightforward welding
- Fits GM 14-bolt housings including ribbed casting variants
- Works with factory leaf perches or add-on coil/leaf spring perches
- Low profile keeps upper-link joints roughly 8" from the axle centerline
- Precision CNC cut and bent to wrap the housing closely
- Made in the USA
Confirm you have the 10.5" full-float 14-bolt, not the semi-float 9.5", before ordering; JKs keeping factory coil buckets should look at Artec's shorter TR1406 truss instead, and some builds may need minor gusset trimming to suit wheelbase and pinion angle. Installation is weld-on with Artec's step-by-step heat and stitch-weld guidance, and the bare steel needs paint or powder coat afterward. Add the 14 Bolt Combo Kit if you want truss plus pinion armor in one buy, see the 8.8 Modular Truss for lighter builds, or browse axle reinforcements and swap kits.
GM 14 Bolt Modular Axle Truss FAQs
Which 14-bolt axles does this truss fit?
It fits the GM 14-bolt 10.5" full-floating rear axle from Chevrolet and GMC 2500/3500 trucks, roughly 1973-2019, including ribbed-casting housings. Make sure you have the full-float 10.5" — the lighter semi-float 9.5" 14-bolt is a different axle. Jeep JKs keeping factory coil buckets should use Artec's shorter TR1406 version instead.
Can I keep my leaf springs and still run this truss?
Yes. The modular design is compatible with factory leaf-spring perches, or you can add Artec's coil or leaf perch add-ons. That means you can truss the axle for a leaf-sprung build now and convert to a linked, coil-sprung rear later without removing the truss.
What does installation require?
Welding — this is a weld-on kit for a competent fabricator. The interlocking pieces self-jig on the housing, and Artec provides step-by-step instructions covering preheating and stitch welding to keep the tubes straight. Depending on wheelbase and pinion angle, minor gusset trimming may be needed, and the bare steel should be painted or powder coated when done.
