This crossmember mounted adjustable torque arm for the 1998-2002 F-Body
is for vehicles running long tube headers/y-pipe set ups.
If you are running Mac mid-length headers and y-pipe, or the Kook's long
tube headers with the Kook's y-pipe, you can use our torque arm package
with the straight crossmember (click
here).
If you want serious performance,
handling, and traction when you're at the dragstrip, AutoX, or road
racing; then you need a Spohn Performance fully adjustable torque arm,
here's what it'll do:
 | Attaches to the rear axle and
controls rear end torque during acceleration, transferring this
energy into the tires, increasing straight line traction
| Reduces nose-dive during
braking
| Eliminates wheelhop
| Increases sidebite during
corner exit acceleration
| Bolt-on system does not require
complete interior removal as with other kits
| No fabrication, welding
or drilling required - 100% bolt-in installation!
| Removes the torque arm pivot
point from the rear of the transmission to the supplied crossmember
| Changes the instantaneous
center and leverage point from stock
| Provides adjustable pinion
angle
| Poly version utilizes
polyurethane front mount to keep noise at a minimum
| Rod ended version utilizes
a QA1 extra high strength, chrome moly spherical rod end
with Teflon®/Kevlar® self lubricating race for those who
demand the best in bind-free performance
and strength
| FREE angle finder
included to set pinion angle |

Build Specifications:
| Constructed of 1.25" o.d.
x .120" wall DOM (drawn over mandrel) seamless mild steel
tubing
| TIG welded 4130 chrome moly
threaded tube adapters
| Heavy-duty 3/8" thick
steel rear housing mounting plates
| Heavy-duty mild steel dual
1.25" x .120" DOM tube crossmember with integral
torque arm mounting system
| Polyurethane bushing front
mount for minimal road noise, Grade 8 hardware is supplied. Integral
grease fitting allows for lubrication of the polyurethane bushing
| Rod ended version utilizes
a QA1 extra high strength, chrome moly spherical rod end
with Teflon®/Kevlar® self lubricating race for those who
demand the best in bind-free performance
and strength. Grade 8 hardware is supplied
| Unique rotating front torque
arm mount, this system allows the torque arm to travel fore/aft
which is VERY necessary with a torque arm suspension system. Solidly
mounting the front of the torque arm causes the suspension to bind
and hurts your car's handling drastically. The front rotator
tube has an integral grease fitting to allow for proper lubrication.
| Rear of torque arm mounts to
the 3/8" thick steel rear housing mounting plates via two
3/4"-16 NFT x 5/8" bore x 7/8" thick solid steel rod
ends. These are solid rod ends, not spherical bearing rod ends, so
noise is of no concern. Grade 8 - 5/8" bolts and 5/8"
nylock nuts are supplied.
| Integral Pinion Angle Adjuster
between the bottom rear solid rod end and the bottom rear torque arm
tube allows for easy pinion angle adjustment. A simple turn of the
wrench will give you 6 degrees of pinion angle adjustment, it's that
simple.
| Entire package is a
complete bolt-in assembly using existing mounting points on the
vehicle. No drilling or welding is required!
| NHRA rules require a driveshaft
safety loop on any vehicle running quicker than 13.99, or on
any car running slicks. NHRA rules call for a loop with at least
.250" wall thickness, located no more than 6" from the
front u-joint. All Spohn Performance driveshaft safety loops meet
every NHRA specification requirement in both build construction, and
mounting location.
| This is a proven
product being run on some of the fastest F-Bodies in the
country!
| Rear mounting bracket is
designed to fit on the OEM rear or an aftermarket 12 bolt or
Ford 9" rear
| Available powder coated red or
black.

By request of our
customers, we now offer the option of getting your torque arm with a
front and rear driveshaft safety loop. NHRA rules call for a
front driveshaft safety loop to prevent catapulting of the vehicle in
the event of a front u-joint or shaft failure. While a rear u-joint or
shaft failure will not catapult the vehicle, it will take out anything
in it's way, ie. rears, suspension components, brake lines, floor
boards, etc. Protect yourself, and your investments, and play it safe by
containing the front and the rear of the driveline.
NOTE: Do not get
a rear driveshaft safety loop if your car is lowered, or if you have an
SLP "Loud-Mouth" cat-back exhaust system.
Compatible with
aftermarket long tube headers and y-pipe. Will clear FLP,
SLP, Grotyohann style and other long tube headers\y-pipe combinations.
Now Available: The
ultimate in bullet-proof lightweight strength, 100% TIG welded
chrome moly construction! Same as above, but torque arm is constructed
entirely from 1.25" x .095" 4130 chrome moly tubing. Make your
choice below.
