TEIN EnduraPro Rear for Lexus GS300,Toyota Crown Athlete (2003-2018)

These shock absorbers are completely compatible with OEM vehicles. As stated, it is a replacement shock absorber. HOWEVER, it is far from a simple replacement. We’ve gone an extra step in making them a high performance shock absorber. In saying that, this product is not the same type of suspension as our existing line of coilovers, which in many cases offer a firmer ride and drastically reduced vehicle body motion (sway, squat, dive). The Endura Pro/Endura Pro Plus line does offer a very comfortable ride quality, but internally it is much different than a standard twin-tube shock absorber you’ll find as an OEM shock.

For starters, we actually have increased the internal capacity of the shock absorbers. In most cases, our Endura Pro/Endura Pro Plus shock absorbers are the same length as an OEM shock (a few applications use a slightly shorter damper body), but we also use larger diameter damper bodies, thus the internal volume is greater. In doing so, we’ve increased damper oil capacity over a standard shock absorber for the same vehicle application. That translates to better endurance (long-term driving) and increased longevity. It also allows us to use a larger than OEM piston valve which provides a greater damping force range.

Since we use the same high-strength steel as used in our coilover kits, it allows us to reinforce areas of the damper, like the lower brackets on strut type suspensions, or the spring seat or sway bar bracket, without a large penalty in weight. In fact, for some applications the Endura Pro shock absorber is actually lighter than OEM!
