SuperTech Dual Valve Spring Kit for Toyota 3SGTE (77 lbs at 35.5mm)

The unique combination of design, metallurgy, and engineering combine to deliver to drivers what they have come to expect from Trimetal high performance engine bearings.

Engineered to withstand high RPM conditions, ACL Race Series Engine Bearings are available for many of the popular 4, 6 & 8 cylinder applications and feature:

High strength overlay plate with reduced thickness for improved fatigue resistance.
Hardened steel backs on all conrod bearings to improve the support of the bearing lining and assist with bearing retention in the housing.
Increased crush for improved bearing retention.
Elimination of flash plating on the back of the bearings to improve heat transfer and to maximize the grip between the bearing and its housing.
Increased eccentricity to compensate for bore distortion at high RPM and to assist in the formation of hydrodynamic oil films.
3/4 grooved main bearings for optimum oil supply to the conrod bearings and to optimize the load carrying surface of the main bearing.
Tight and consistent wall tolerances to maintain consistent clearances. Enlarged ID chamfers on bearing edges, where required to accommodate large fillet radius on high performance crankshafts.
