1L302 Air Spring, suspension (Autopa OE-Spec Replacement)

The 1L302 Air Spring, suspension is a Autopa air spring strut listed under our
Air Spring Strut category at
CG Auto Parts Shop. Every listing includes a full manufacturer cross-reference
table so you can confirm fitment by part number before you order.

How It Works

An air spring strut replaces a conventional coil spring with a pressurised rubber-and-textile air bellows, fed by the vehicle’s air suspension compressor. This allows the ECU or driver to adjust ride height and spring rate dynamically in response to load, road conditions, or a pre-set profile, providing a noticeably softer and more adaptable ride than a fixed-rate spring.

Signs You Need a Replacement

A vehicle that sits noticeably lower on one corner, slowly sags overnight, or triggers an air suspension warning light typically has a failed air spring bellows, a leaking valve block, or a worn compressor. Continued driving on a deflated air spring transfers load directly to the metal bump stop.

Brand & Manufacturing Authority

This air spring strut is manufactured by Autopa, a recognised supplier
to the automotive aftermarket. The part number 1L302 identifies this specific
unit in the manufacturer’s own catalog. It is supplied new — not remanufactured — and is backed by our
warranty policy.

Material & Construction

Built from multi-ply rubber-textile bellows with a reinforced nylon outer braid on the roll piston, bonded to an anodised aluminium or steel upper mounting and a polyamide lower piston. This construction is chosen to match or exceed the OE
specification it replaces under the same load, temperature, and service conditions.

Fitment Confidence

Year-make-model filters alone can miss mid-year production changes that affect fitment. The safest
method is to match the part number stamped on your existing air spring strut against the
cross-reference table below. If you can’t locate your existing part number, send your vehicle VIN
through our contact page and we’ll confirm before you order.

Product Specifications

Cross-Reference Compatibility Table

Match your existing part number against this table before ordering. All data is drawn directly
from the manufacturer’s own cross-reference documentation.

Installation & Safety Notes

Depressurise the system before disassembly. Confirm the replacement matches the air line fitting size and connector type. Inflate to ride height and check for audible leaks at all unions before road testing. Always follow your vehicle manufacturer’s torque specifications and service
manual procedure. For the engineering standards that govern this part category, see the
SAE International suspension standards.

Quality Assurance

We verify every listing’s cross-reference data against the manufacturer’s own catalog before
publishing. We sell Autopa parts because the brand has a documented track record in the
air spring strut category. If a part number doesn’t match your vehicle after
checking the table above, contact us and we’ll find the correct one.

Choosing the Right Air Spring Strut — A Buyer’s Guide

Shopping for a air spring strut by part number rather than by vehicle
model alone is the most reliable way to avoid a fitment mismatch. A year-make-model filter is a
starting point, but the same vehicle model can use different component specifications depending on
trim level, engine variant, and production date. The cross-reference table above is built from
the manufacturer’s own part-number data, which means the relationship between this part and the
vehicle application is confirmed at the component level rather than inferred from model data.

When you receive the new air spring strut, compare it physically against
the old part before installation — check overall dimensions, mounting hole positions, and connector
orientation. A direct visual comparison catches any discrepancy before time is invested in
disassembly. If anything doesn’t match despite the part number confirming correctly, contact us
before installing, since we can usually resolve fitment questions the same day.

We source our Autopa parts directly through authorised supply
channels to ensure you receive the genuine part that the cross-reference table confirms. Aftermarket
quality varies enormously by brand; listing the actual manufacturer — rather than a generic
“compatible with” label — is how we give you the information needed to make a confident buying
decision. The About Us page explains our approach to sourcing and
part-number verification in more detail.

After Installation — What to Check

Once the new air spring strut is fitted and torqued to specification,
a brief test drive under controlled conditions is the best way to confirm the repair is successful
before returning the vehicle to normal use. Listen for any new noises from the affected area at low
speed over a rough surface, and confirm that the system behaviour feels correct. For suspension and
steering components, a wheel alignment check immediately after installation is strongly recommended,
since even a correctly fitted new part can require alignment correction compared to the worn part
it replaced. For braking components, a proper bed-in procedure — a series of graduated stops from
road speed — transfers an even layer of friction material and settles the new components before
maximum braking loads are applied.

Keep the installation date and part number noted in your service records. This information is
required if a warranty claim becomes necessary, and it makes future parts sourcing straightforward
since you’ll have a confirmed part number on file. Our warranty
policy page specifies the documentation needed to support a claim.
