Technical inventory of heavy-duty off-road suspension links, auxiliary LED lighting pods, electronic engine calibration modules, and laser-cut protective chassis armor.
Vehicle components verified for California off-road expeditions.
Off-road suspensions require verified shock eye-to-eye stroke and anti-roll bar drop clearance before bolt-up. We do not sell universal slip-on hardware that relies on slotted friction clamps for structural retention. Every component on this page is quoted by item based on exact chassis model, year of production, harness architecture, and installation readiness.
Billet recovery points and tubular bumper kits ship with grade 10.9 zinc-plated hardware. Order processing runs strictly 1 to 3 business days from technical fitment clearance by our San Juan Capistrano parts manager.
Heavy-Duty Suspension & Steering Hardware Kits: Chromoly tie rods and rebuildable spherical bearings built for severe washboard trail harmonics.
Heavy-Duty Suspension & Steering Hardware Kits
Engineered for high-articulation trail vehicles that experience sustained high-frequency washboard vibrations. Factory stamped steering links buckle when thirty-five-inch or thirty-seven-inch tires bind against granite shelves. Our assemblies use aircraft-grade 4130 chromoly bar stock, heat-treated chromoly shank rod ends, and precision CNC-machined 17–4 stainless steel misalignment spacers.
Individual components range from $8 for high-strength jam nuts, misalignment spacers, and zinc-plated grade 10.9 replacement bolts up to $1,740 for complete double-shear steering conversion kits with high-angle spherical rod ends and forged chromoly drag links.

Auxiliary LED Lighting & Relay Harness Pods: Mil-spec sealed Deutsch DT connections with integrated thermal throttling heat sinks.
Auxiliary LED Lighting & Relay Harness Pods
Auxiliary lighting pods draw up to 8.2 amps per pair and require dedicated relay protection. Splicing high-output LED pods directly into factory fog light wires melts factory wire sheathing and triggers CAN-bus lighting error faults. Our auxiliary lighting packages include application-specific relay wiring harnesses with 40-amp potted relays, inline waterproof fuses, and genuine Deutsch DT connectors.
Hardware units span from $45 for replacement Deutsch harness extensions, relay adaptors, and stainless mounting brackets up to $890 for pair kits featuring machined aircraft aluminum housings, copper-core circuit boards, and thermal throttling drivers that safeguard LEDs in desert heat.
| Lighting Unit | Optical Output | Current Draw | Connector Type | Inquiry Price Basis |
|---|---|---|---|---|
| Amber Dust Cornering Pod Pair | 4,800 Raw Lumens per Pair | 3.8 Amps @ 13.8V DC | Sealed Deutsch DT 2-Pin | $185 – $320 / pair |
| High-Velocity Spot Light Pod Pair | 9,500 Raw Lumens per Pair | 7.6 Amps @ 13.8V DC | Sealed Deutsch DTP 2-Pin | $420 – $890 / pair |
| Potted 40A Relay Loom with Switch | Automotive 14AWG TXL Wire | 40 Amp Continuous Duty | Dual DT Output Plugs | $45 – $135 / loom |
High-Flow Intake Filtration & Power Adaptors: Hydrophobic dry media filtration preventing silica dust intrusion in extreme desert silt.
High-Flow Intake Filtration & Power Adaptors
Oiled gauze air filters foul mass airflow sensors when fine talcum silt mixes with filter oil on high-speed trail runs. We supply multi-layer synthetic dry media filters that maintain high cubic-feet-per-minute flow while capturing particles down to 0.5 microns. Each kit includes a silicone velocity stack adaptor, stainless T-bolt hose clamps, and a water-repellent pre-filter sock for deep creek crossings.
Replacement hydrophobic pre-filter socks and wiring adaptors begin at $38, scaling up to $480 for complete sealed rotational-molded polyethylene airboxes with mandrel-bent aluminum intake tubes.
- Dry synthetic non-oiled media eliminates MAF sensor contamination and oil blow-by.
- Four-ply silicone couplers rated from -65°F to +350°F under heavy underhood thermal soak.
- Direct replacement of restrictive factory intake baffles without requiring permanent body cuts.
Engine Calibration Modules & Electronic Tuning Packs: Direct plug-and-play CAN-bus modules configured for low-end crawler torque and temperature monitoring.
Engine Calibration Modules & Electronic Tuning Packs
Tuning modules and harness adapters are calibrated to vehicle harness pins, not universal tap splices. Adding larger tires, steel skid plates, and roof equipment loads factory engines down, causing automatic transmissions to hunt for gears on steep canyon grades. Our electronic modules remap throttle response, optimize torque converter lockup curves, and correct the speedometer for oversized tire rolling diameters.
Basic handheld calibration devices start at $690, while fully telemetry-integrated engine and transmission control packs with exhaust gas temperature probes and wideband oxygen sensors reach $5,080. Every calibration module connects directly to vehicle factory harness connectors without cutting or splicing factory wires.
| Tuning Kit Level | CAN-Bus Protocol | Calibration Functions | Wiring Harness | Inquiry Price Basis |
|---|---|---|---|---|
| Speedo & Throttle Calibrator | OBD-II CAN-Bus Pinout | Tire Diameter & Gear Ratio Calibration | Factory Connector T-Harness | $690 – $950 / kit |
| Transmission & Crawl Tuner | Engine + Transmission CAN-Bus | Shift Point Shift & Torque Limiter Mod | Braided Raychem Mil-Spec Loom | $1,450 – $2,380 / kit |
| Complete Engine Telemetry Pack | Dual CAN + External 5V Analog | Real-Time EGT, Boost, AFR Logging | Gold-Plated Terminal Deutsch DT | $2,900 – $5,080 / kit |
High-Clearance Fender Eliminators & Inner Liners: Laser-cut 5052 aluminum panels designed for full articulation with 37-inch trail tires.
High-Clearance Fender Eliminators & Inner Liners
When fitting thirty-five-inch or thirty-seven-inch off-road tires, factory plastic fender liners tear out on the first full-compression bump stop strike. Our inner fender liners and fender-eliminator brackets are CNC laser-cut from 5052-H32 marine-grade aluminum sheet. They provide direct clearance for high-travel suspension coilovers while shielding engine bay wire looms and brake lines from flying gravel.
Inner liner sets run from $120 for raw aluminum front inner replacement plates up to $760 per pair for powder-coated front and rear inner fender assemblies with integrated mesh ventilation and stone deflector panels.
- 5052-H32 aluminum sheet with 1/8-inch thickness for stone deflection without weight penalties.
- Precision clearance notched for remote-reservoir shock hoses and extended hydraulic bump stops.
- Includes stainless steel button-head hardware and captive rubber anti-vibration grommets.
Tubular Rock Sliders, Bull Bars & Chassis Mounts: Mandrel-bent DOM steel tubing welded with integrated frame gussets and zinc-coated hardware.
Tubular Rock Sliders, Bull Bars & Chassis Mounts
Protective skid plates and rock sliders must support the entire vehicle weight when dragging across boulder fields. We construct rock armor using 1.75-inch outer diameter DOM (Drawn Over Mandrel) carbon steel tubing with a 0.120-inch wall thickness. Frame mounting plates are 3/16-inch laser-cut plate steel gusseted to distribute trail impact loads across the vehicle’s structural frame rails rather than the thin floor pan.
Replacement mounting hardware, gusset plates, and heavy-duty frame sleeve bolts start at $9 to $140 per piece. Complete structural rock slider sets and modular bumper bull bar assemblies are quoted per vehicle frame configuration based on whether bolt-on or weld-on chassis sleeves are specified.
| Protective Assembly | Structural Material | Attachment Protocol | Finish Treatment | Inquiry Price Basis |
|---|---|---|---|---|
| Frame Gusset Plates & Sleeves | 3/16" High-Tensile Steel Plate | Weld-In or Bolt-Through Sleeve | Raw Oiled Carbon Steel | $9 – $48 / piece |
| Grade 10.9 Armor Fastener Pack | High-Tensile Quenched Steel | Flanged Hex Head Bolt & Lock Nut | Yellow-Zinc Corrosion Plating | $18 – $140 / pack |
| DOM Steel Rock Slider System | 1.75" × .120" DOM Carbon Tubing | Bolt-On to Factory Frame Rail Holes | Textured Black Powder Coat | Quoted per chassis |
| 3/16" Aluminum Transfer Case Skid | Laser-Cut 5052-H32 Aluminum | Recessed Flat-Head Fasteners | Bead-Blasted Bare Aluminum | Quoted per chassis |
