Lingenfelter, an aftermarket company known for its Camaro and LS engine accessories, has announced upgrades for 2010-12 Camaro SS rear-end gears. The company offers two options: 3.70 and 3.91 ring & pinion setups. Both will give you a 7-13% rear wheel torque increase. The gear sets fit both manual and automatic transmission Camaro SS differentials. Only the automatic transmissions will need ECM programming to correct for the speedometer reading; this programming is available through Lingenfelter.
Here are some more details about the two gear options:
The 3.70 ring & pinion setup features a 10-tooth pinion and 37-tooth ring design. The gears will provide a 7% increase in rear wheel torque for manual transmission vehicles and a 13% for automatic-equipped vehicles. Manual transmission vehicles will see a growth of 100 RPM while cruising at 60 mph in 6th gear, while automatics will see an even larger rise of 220 RPM.
The 3.91 ring & pinion setup features a 11-tooth pinion and 43-tooth ring gear design. This setup is made more for increased torque in quarter-mile racing. It delivers a 13% increase in rear wheel torque for manual transmissions and a 20% increase for automatics. While cruising at 60 mph in 6th gear, a manual transmission vehicle will see an increase in engine speed of 180 RPM; automatic transmissions gain 300 RPM.
Lingenfelter ring & pinion sets are available as a ring & pinion only or as a complete differential assembly. The differential assembly is available as a new assembly or built from the customer's core.
