WEVO are famous for their gear shift levers and transmission upgrade parts for air cooled 911s, but the company also makes some interesting suspension parts. One such part is the WEVO E-Z Pin.

The WEVO E-Z Pin is designed to replace the 14mm bolt used on the inboard pivot of the 911 rear trailing arms. The 1972 911s do not have the dimpled torsion tube to allow the inboard bolt to be removed unless the transmission is removed from the chassis.

The E-Z Pin will fit the 1965-1989 Porsche 911, and can be installed with the transmission in the chassis, eliminating the cost and inconvenience of removing the transmission when performing rear suspension rebuilds or upgrades.

The original bolt is removed by partially extracting the bolt, then cutting the exposed section of the bolt. This is necessary as the O.E. bolt can not be removed or installed when the transmission is in the chassis. The E-Z Pin was not available when I had to change a split trailing arm bush on my SC Cabriolet a few years ago. If it had been, I’d certainly have fitted it.

The EZ Pin can be used with original bushings or aftermarket monoball and spherical bearing replacement parts.

Trailing arm bush replacement can be tricky. The bolts sometimes seize in place, with plenty of penetrating oil and a healthy amount of heat being the best allies in loosening the bolts. To do this most easily, a partial- if not complete engine drop is advantageous. The best solution is, when the engine and transmission are next out of the car, ensure you buy and fit the E-Z pins. Make life much easier when you decide to add monoballs or nylon suspension bushes in the future.

New trailing arm bushes can tighten up the rear of an early 911, and are well worth doing if your car is still running the original parts. Check through your history!
