In search of the very highest quality and performance, the MED 1.5:1 LDX roller-tip rockers are the result of over a decade of testing and development work on high-end competition engines.
Bridge-section rocker arms, an extra large diameter rocker shaft and ‘W’ section rocker posts all help to increase torsional rigidity and maintain valve train geometry.
Design features:
- Greater contact area between the rocker shaft and the rocker arm with 17mm diameter shaft.
- Full captive rocker post design to encapsulate each rocker arm between a pair of rocker posts and reduce flex.
- Bridge-section rocker arms reduce flex at high rpm.
- The rocker arms are wider in the front section to give greater roller pin support.
- Roller pins have three locations to achieve maximum rigidity
- The rollers are cylindrically ground to achieve precise valve lift across the head.
- Offset option for full-race heads with offset exhaust valves.
Please note – the arm spacing of our rocker assemblies makes them suitable for 1275, 970(S) and 1071(S) based engines only. They will not suit small-bore (850, 998,1098 etc) cylinder heads.
