Torque Rating Comparisons
SR15X=180 ft lbs., SR17X=250 ft lbs., IB RD = 534 ft lbs.
The 4.44 to 1 reduction provides over 4 times the torque of standard starters. Even cranks a V8. Ideal for high compression or engines with blowers. Cranks at normal cranking RPM without slowing down. For the weight conscious person it only weighs 9 pounds. That's 3 pounds less than the stock SR15X and 4 pounds less than the SR17X. SW #11
Note: Starters with -R and -RC are special made with the solenoid rotated to 3 o'clock (looking from the rear of the car) for applications where the exhaust interferes with the solenoid at the normal 1 o'clock position. The RD and RD-C have the solenoid at 1 o'clock (looking from the rear of the car).
