Chassis Components – Crossmembers, Body Mounts, Outriggers & Brackets
Chassis components refresh the structure and mounting points of your 4x4. Replace worn crossmembers, body mounts/outriggers and suspension/brake line brackets with vehicle-specific parts designed to maintain geometry, strength and service access.

Key Features
- Press-formed or boxed crossmembers with OE datum references
- Body mounts/outriggers with correct bush seats and hole centres
- Spring/shock mounts and accessory brackets with reinforcement
- High-strength steel; e-coat/primer or powder coat (model dependent)
- Bolt-on and weld-in options with hardware packs
Quick Comparison – Common Components
| Part | Function | Install | Best For | Watch Outs |
|---|---|---|---|---|
| Crossmember | Chassis stiffness, driveline support | Bolt-on/weld-in | Rust replacement, gearbox swaps | Driveline angle, exhaust clearance |
| Body Mount/Outrigger | Body-to-frame interface | Weld-in with bush service | Cab/body alignment | Set mount height before final weld |
| Spring/Shock Mounts | Suspension location | Weld-in | Rust/crack repair, upgrades | Bracket clocking; torque at ride height |
| Utility Brackets | Brake/fuel, loom routing | Bolt or weld | Tidy serviceable routing | Avoid sharp edges/heat sources |
Buyer’s Checklist – How to Choose
- Identify datum points and measure before removal
- Match bush style/height and hole centres to your vehicle
- Decide bolt-on vs weld-in for serviceability and regulations
- Allow for exhaust/driveline clearance around crossmembers
- Order hardware (high-tensile bolts, crush sleeves, washers)
Fitment & Compatibility Guide
Maintain geometry during replacement.
- Jigs/props: support chassis and body to prevent twist
- Mock-up: bolt loosely, verify alignment, then final torque/weld
- Angles: confirm pinion/transfer case angles after crossmember work
- Bushes: torque mounts with vehicle at ride height
- Protection: top-coat and inject cavity wax in boxed sections
Care & Durability
- Re-torque structural fasteners after 500–1,000 km
- Inspect coatings after off-road trips; touch up chips
- Check for cracks at weld toes and bracket edges
- Keep drain holes clear in boxed members
- Grease/replace body mount bushes as required
Upgrade Sequence Roadmap
- Measure and mark datums; support chassis/body
- Replace crossmembers and body mounts
- Install spring/shock mounts and utility brackets
- Torque at ride height; verify driveline angles
- Seal, top-coat and apply cavity wax

FAQ – Chassis Components
- Do I need to remove the body to change crossmembers?
- Not always; many are serviceable in situ. Large boxed sections or obstructed fasteners may require lifting the body.
- Bolt-on or weld-in crossmember?
- Bolt-on eases future service; weld-in can restore OEM strength where the original was welded. Follow vehicle-specific guidance.
- How do I set body mount height?
- Use OE datum measurements and shim/bush stacks; torque at ride height to avoid pre-load.
- What hardware grade should I use?
- High-tensile (e.g., 8.8/10.9) as specified. Replace any stretched or corroded bolts and use correct washers.
- Will a new crossmember change driveline angles?
- It can. Verify output and pinion angles after installation and adjust shims or mount height if needed.
- Can I weld near fuel/brake lines?
- Relocate or shield lines and disconnect the battery. Keep a fire watch and extinguisher nearby.
- Do I need to re-align the vehicle?
- Recommended—check wheel alignment and inspect bush torque after a short shakedown.
- How do I protect new components from rust?
- Top-coat exposed steel, inject cavity wax in boxed members and rinse mud/salt regularly.
