The LPE 9.5” (241mm) Camaro differential is a custom designed differential assembly made to fit
the 2010-2013 5th Generation Camaro. This heavy duty 356 cast aluminum differential housing is
designed to use 9.5” diameter 14 bolt ring and pinions normally used in GM OEM full size trucks.
This allows the use of high strength proven OEM type ring and pinions that also provide low gear
noise. The differential mounts using the OEM mounting locations and accepts the OEM or aftermarket
bushings made for the stock differential. The larger design of the 9.5” differential assembly does
require the use of new half shafts and driveshaft (not included). The 9.5” differential assembly weighs
108 lbs with no fluids. This is roughly 33 lbs heavier than the OEM 218 mm Camaro SS differential
which weighs 75 lbs with no fluids.
The LPE cast aluminum 9.5” Camaro SS differential assemblies include American Axle TracRite® GT
Helical Gear Limited Slip Carrier Assembly, ring and pinion set all built at American Axle. This gives
long life and quiet operation to the differential.
Features of the American Axle TracRite® GT - Helical Gear Limited Slip Carrier
- Smooth, quiet operation
- Torque sensitive design instantaneously biases torque before differentiation begins
- Tunable bias ratio
- Can be used with or without a pre-load feature
Ring and pinion ratio options are 3.42, 3.73, 4.10, and 4.56. The LPE 9.5” differential is available with
or without pre-load on the limited slip differential. Most street and drag racing applications will want a
differential setup with pre-load for a better reaction on initial launch. Having pre-load does add some
handling understeer, or “push”, so road racing applications will likely want a differential with no pre-
load.
LPE recommends the use of the OEM GM 75W90 synthetic differential fluid (PN: 9986226) in the
LPE 9.5” differential. The fluid volume varies slightly depending on the gear ratio. A 3.73 ring and
pinion requires roughly 4 quarts of fluid.
The recommended break in period is light duty usage for the first 500 miles. If this is not possible then
use a break-in schedule of ten (10) acceleration runs from 25-65 MPH with a cool down time between
each run. The reasoning for this is to ensure slight wear on the differential gear without overheating
the unit. Be sure to avoid extended runs at high power and load, as well as high sustained vehicle
speed during the break in period of 500 miles.
