Thule Roof Bars – Changing Cars? What Parts Do You Need to Replace | Roof Boxed

Thule Roof Bars – Changing Cars? Here’s What You Need To Do

If you’re changing cars and already own Thule roof bars, you’re probably asking:

“Will my Thule roof bars fit my new car, or do I need a whole new system?”

The good news? In many cases, you won’t need to replace everything. Thule roof rack systems are modular, meaning individual components can often be reused when you switch vehicles.

This guide explains exactly what to check, what might need replacing, and how to save money with expert advice and part exchange from Roof Boxed.

How Thule Roof Bars Work (And What Might Need Changing)


Thule roof bars are modular, so you may be able to reuse parts when changing cars.

A complete Thule roof rack system consists of three main parts:

  1. Load Bars – e.g. WingBar, SquareBar or ProBar
  2. Foot Pack – attaches the bars to your vehicle
  3. Fit Kit – vehicle-specific brackets designed for your exact make and model

Key Takeaway:

When changing cars, you may need to change one, two, or possibly all three components of your Thule roof bar system — the fit kit, foot pack, and/or load bars — depending on your new vehicle’s roof type and dimensions.

Because Thule systems are vehicle-specific, switching from something like a Volkswagen Golf to a BMW X3 will almost always require a different fit kit, and sometimes a different foot pack. You may be able to reuse your existing bars if they are the correct length for your new vehicle.

If you’re unsure what you need, contact us at Roof Boxed and we’ll confirm the exact parts required for your new car — and help you part exchange any components you no longer need.

Step 1: Check Your New Car’s Roof Type

Different vehicles use different mounting systems, including:

  • Flush roof rails
  • Raised roof rails
  • Fixed mounting points
  • Bare / Normal roof
  • T-Tracks

Even different versions of the same model can require different fit kits depending on the year. For example, moving from a hatchback to an SUV or estate model often changes the roof setup entirely.

If you’re unsure, Roof Boxed can check compatibility for you before you purchase anything: contact the team.

Step 2: Identify What You Currently Own

Before replacing anything, check:

  • Bar model (WingBar, SquareBar, ProBar)
  • Bar length
  • Foot pack type
  • Existing fit kit number

Often, customers only need to replace the fit kit, which is usually the most affordable part of the system.

When You Might Need a Completely New System

In some cases, you may need to replace everything:

  • Your bars are too short or too long
  • You’re moving from roof rails to a bare roof
  • Your current system is outdated
  • Your foot pack isn’t compatible

Some vehicles use fixed mounting points that require specific fit kits. If you’re unsure, always check before buying — it can save you hundreds.

FAQs: Changing Cars With Thule Roof Bars

Can I reuse my Thule roof bars on a new car?

Possibly — if they are the correct length and compatible with the required foot pack and fit kit.

Are Thule fit kits universal?

No. They are designed for specific makes, models, and years.

Is it cheaper to replace parts or buy a full system?

In many cases, replacing just the fit kit is significantly cheaper. If more parts are needed, part exchange can reduce overall cost.

Final Advice: Replace Only What You Need

Changing cars doesn’t automatically mean replacing your entire roof rack system.

In most cases, you’ll need between one and three components — not a full setup.

  1. Identify what you already have
  2. Check compatibility
  3. Ask an expert
  4. Part exchange the parts you don’t need
