Rear mounting bracket designed to mount on to stock, 12 bolt, or Ford 9 rear
Constructed of 1.25 o.d. x .120 wall DOM (drawn over mandrel) seamless mild steel tubing
Heavy-duty mild steel 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 chrome-moly spherical rod end front mount for the ultimate 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.

Spohn Performance 405-FL-4130 Torque Arm Review(s)
Reviews for Spohn Performance 405-FL-4130 (the item on this page) are show below.
By: SS demon Ownership: 1 month - 1 year Easy install, recommend a lift. You will need to jack up the engine, the old front sway bar wouldn''t come out so we had to cut it in half. New front sway bar went in with no issues. I used my stock links, been on for 5k with no issues.
You will need to purchase the bmr rear sway bar brackets to insure the stock ones do not break due to being flimsy.
These bars really keep you in the corners!!!
Current Mods: Spohn sway bars, bbk long tube headers, stainless works muffler deletes, vararam cold air intake, bmr sway bar brackets.
By: Anonymous Ownership: 1 day - 1 week The stock tunnel brace on my Camaro was a joke. Was just a thin piece of stamped steel you can actually bend with your hand. The Spohn tunnel brace really stiffened up the chassis by itself and stopped the majority of "wiggles" associated with convertibles (before I installed the sub-frame connectors which ended all "wiggles"). I recommend this product.
Current Mods: UMI 3-point sub-frame connector (convertible), Spohn tunnel brace, Spohn strut tower bar
By: jksz28 Ownership: 1 week - 1 month This torque arm is far better then the stock arm. I had to replace the stock because it cracked and bent. When getting this spohn arm you can clearly tell why it's so much better then the stock one. Even if your car is stock its far to dangerous to run with the factory torque arm. In fact I'd say its life threatening. Oh! and I did notice an improvement in cornering.
Current Mods: magnaflow catback exhaust, pacesetter LT headers with y-pipe, slp cold intake, spohn adj torque arm
By: PNYKILR (ponykiller) Ownership: more than 1 year I really love how easy this x-member went in and bolted to the car. The adj t/a makes pre-load a snap. The whole set up just looks sexy sittin' under there in black. The only thing I might change is the fact that there is no way to get a socket on the bolts for the trans mount to bolt it to the tailshaft, a challenge to get a wrench on it. The access holes have to be drilled out big enough to get a socket on them. Please let me know if there is a different way. I will definitely be buying more Spohn products for this dirty bird. Sub frame connectors are next. Need a good sized decal to put on the car also. (Wink Wink)
Current Mods: 496 Hp/542lb-ft 383, Wilsons Transmissions TH400 w/ rev valve body, killer shift kit (snap ur head off & put in the back seat w/a smile u cant chissel off) & a Wilson's 10" 3500 stall. MSD Digital 6+ box. Spohn trans mount w/adj t/a. Heddman full tube headers, 3" pipe to Super 44's dumped @ the rear floor pan. '88 IROC rear end w/ disc brakes, True-Trac Posi, Richmond 4.10's. Six point cage.
