New Supra Valve Springs and Titanium Retainers
Crower's new Toyota Supra 2JZ valve springs and titanium retainers are available for the high lift, high rpm applications.
The new single valve spring delivers 15% more pressure across the board than the factory part.
Also, with a coil bind of 0.820", the Crower spring allows for more cam lift than factory springs will allow. Crower titanium
retainers weigh in at 7 grams vs. stock steel at 14.5 grams.
Pickup additional rpm's by reducing valve train weight.
Specify #87085 for the Crower titanium
retainers. Spring pressures are listed below. |

failure. #86054T (each sold seperately). |
