Heavy-Duty Weld-In Rear Torsion Adjuster | VW Type 1 Adjustable Ride Height

Model #CH07

Dial in your VW's stance with a turn of a screw. This weld-in rear torsion adjuster lets you independently raise or lower each side of your classic Volkswagen's rear suspension to achieve the exact ride height and rake you want — whether you're slamming a street Bug, leveling a daily driver, or setting up an off-road build.

Cut the center section out of your rear torsion housing, weld this unit in, and you gain fully adjustable rear ride height without guesswork, shims, or re-indexing torsion bars. Built heavy-duty to take abuse on the street or in the dirt.

Why Builders Choose It

• Independent left/right adjustment: Set each side separately to correct lean or dial in a custom stance.

• Lift or lower at the turn of a screw: No need to pull and re-clock torsion bars every time you want a height change.

• Heavy-duty construction: Engineered to withstand the loads of off-road and street-performance use.

• Weld-in design: Becomes a permanent, structurally sound part of your chassis.

Vehicle Fitment

• Beetle: Type 1 swing-axle and IRS rear suspension

• Karmann Ghia: Type 1 chassis

Installation Note

This is a weld-in suspension component for experienced fabricators. Proper installation requires cutting the rear torsion housing and welding the adjuster in square and true. If you're not comfortable with chassis welding, have a qualified shop perform the install.

Frequently Asked Questions

• Does this work on swing-axle and IRS? Yes — it adjusts ride height at the torsion housing, so it works with both swing-axle and IRS rear setups.

• How much can I raise or lower the car? The adjuster gives a wide range of travel; final range depends on your spring plates and trailing arm geometry.

• Is this reversible? No — it's a weld-in modification. Plan your stance before cutting.
