WHAT'S NEW
New: Docol® Tube Option
Docol® tube is now available for select chassis builds and components. It delivers roughly 10–15% higher strength than 4130 with improved fatigue performance and a smaller, more tolerant heat-affected zone. With a clean mill finish and consistent properties, it typically requires less prep, resists warping/distortion, and welds up more predictably — ideal for high-stress chassis work.
Weld compatibility: TIG/MIG; welds to 4130 and mild steel.
Mini Rod Tractor Pulling Chassis Parts — Built for Real Pulls
GlineRacing designs and supplies precision laser-cut chassis components for mini rod tractor pulling. Our flagship TrussLok rail system applies truss engineering to deliver stiffness, adjustability, and a clean bolt-on mounting grid — without the weight penalty of overbuilt rails.
Order complete rail kits or individual chassis parts including motor plates, rear end mounts, and mounting plates. We offer multiple material options so you can match strength, corrosion resistance, and budget to your build.
Popular thicknesses
- Rails: 1/16"
- Rear end mounting plates: 1/4"
- Front center pivot motor plate: 1/2"
- Movable weights: 1/2"
Material options
- 4130 chromoly: maximum strength
- 304 stainless: corrosion resistance
- HRPO mild steel: budget/performance balance
- Docol: 10-15% stronger than 4130, better fatigue behavior
Compliance note: our parts are designed with mini rod tractor pulling rules in mind (including NTPA/PPL considerations). Always verify your class rules and your specific build requirements.
Lead time: custom laser-cut parts typically ship in 1-2 weeks. US customers only.
Why TrussLok Rails Perform Better
Textbook truss engineering applied to a rail system for mini rod racing chassis
Insane Strength-to-Weight Ratio
Triangulated design puts material exactly where it fights compression/tension best. You get stiffness that rivals thick tube frames but at a fraction of the weight—critical for mini rods where every pound affects pull, hookup, and speed.
Axial Load Efficiency
Members only see push/pull → you can use thinner/lighter extrusions (aluminum or steel) without buckling or sagging. No wasted material resisting bending like in a plain rectangular rail.
Built-in Rigidity & Torsion Resistance
The truss web (those diagonal braces) prevents the rail from twisting or buckling sideways under torque from the engine/hitch or lateral pull forces. In pulling, where you slam huge shear and twist into the frame, this triangulation is gold.
Modular / Bolt-On Heaven
The pre-drilled hole pattern in your extruded truss profile turns the rail into a giant mounting grid. Every intersection is a potential 1/4" bolt point → attach brackets, engine mounts, suspension tabs, body panels, ballast, whatever—all bolt-on, no welding required for mods.
Adjustability & Serviceability
Want to move a mount? Unbolt and shift it to another hole grid spot. Smash a rail? Replace just that side truss instead of torching the whole chassis.
Vibration & Fatigue Resistance
Even load distribution + no bending stresses = less cracking over time. Pulling tractors beat the shit out of frames; truss spreads the abuse better.
