What to Look for before Buying

Not sure what to look for in an inner fender? We’ve got you covered!


Like any other car component, it is essential to make sure your fenders or fender liners of choice match the specifications of your car.

An Ill-fitted inner fender, regardless of the quality, will be rendered useless if it is not meant to be used with the make and model of your car. A little research always pays off!


Most inner fenders are made of either steel or aluminum – these are also the best performing materials.

However, both steel and aluminum fenders have their own fair share of pros and cons.

Examine your driving style and average driving conditions before you decide on a material.


Closely related to the material is the finishing. Fenders are available in both raw aluminum finishing and black powder coating.

Powder coating adds the extra oomph to the fenders by making them more durable and aesthetically pleasing.

However, fenders of good quality will perform great even without the coating – pick wisely!

Resistance to Elements

Material and finishing also determine how resistant the fenders are to the elements.

If you like taking your car out for a spin on muddy trails, as do most Jeep Wrangler owners, you will benefit from fenders that do not get damaged in water.

Corrosion and rust resistance is also really important for durability.

Airflow and Ventilation

Not all inner fenders promote ventilation and airflow to the engine or engine bay – and you would be better off keeping away from those that do not! Airflow and ventilation not only keep your engine healthy, but it may also increase horsepower and acceleration power.

Access to Shock

Some inner fenders block access to the Jeep’s shock. Any sort of repair or observation requires the inner fenders to be taken out first.

While this is not mandatory, it is worth looking into which fenders allow access to the shock without being removed first – the ease of access may be a great bonus!
