The original Land Rover design for the window studs have a round diameter mild steel stud threaded on both ends that used a plastic symmetrical cylindrical tube bushing for the aid in removal and installation of windows. Since it is made of steel and even though it is yellow CAD plated, the threads and the diameter corrodes into place making removal of window difficult. The outside diameter of the plastic bushings that is intended for a spacer is the same circumference and length of the mounting hole in the door thus making it difficult to align when corroded onto the original steel stud. Also there is no provision for a wrench or socket to tighten the product into place to proper torque specifications, the only way is to use a pair of Vice Grips™ or other Channel locks. It is a two-piece design in which uses plastic sleeves that are difficult to align and cumbersome to install. The studs being made of mild steel the strength is weaker and susceptible to failure due to the inherent properties of the material.

Upgrade

Our window stud uses a high tensile 304 Stainless Steel to prevent rust & corrosion. The taper design at the beginning diameter aids in installation for skewing and self-guiding into mounting holes of the doors. The hexagonal design is turned down to match the OEM original size & clearance of the mounting hole size. This provides a number of benefits.

1. It gives a wrench / socket flat for proper tightening procedures.

2. It provides less area contact around the circumference with no loss of diameter because of the shape of the hex.

3. It provides a path for rain & moisture to pass thru distance between the hex and the mounting hole to prevent the aid of corrosion.

4. It replaces one less item (plastic bushing) that is very difficult to keep in place while installing the original steel stud.

5. Since the material has a higher Yield strength than the original the failure of deformation is much less.

Using our STUD-EEZ makes for no stress removal of D90 Soft Top Windows.
