Fitment & Compatibility

Notes & Recommendations

• Though you requested “1.3–3.6″” front lift, actual usable lift depends on coil spring rates, suspension geometry, bump stops, and clearance. Check full suspension travel after install.

• Ensure rear shock length and travel match your rear lift and load conditions. Over-extending rear shocks can lead to binding or damage.

• After install, always perform a full alignment (camber, toe, caster) to account for new geometry.

• Verify clearance on fenders, brake lines, ABS sensor wiring before finalizing lift settings.

• For heavier builds or overlanding gear, consider matching rear heavy-duty coil or load-support upgrades in conjunction with shocks.
