This is very crucial on low to mid horse-power cars and can easily lower 60-foot times.

This unit is designed with a drop down front cross member to clear most to all aftermarket header/y-pipe set-ups on the market. This system has been confirmed to clear with Hooker Header/y-pipe system, Pacesetter headers with Pacesetter y-pipe and TSP y-pipe also SLP header/y-pipe system as well as many others. If you are running Kooks long tube header set-up we recommend our other version since this system tucks up very nicely.

Front Drive Shaft Loop- This item is supplied with a NHRA legal drive shaft loop. The front drive shaft loop has been confirmed to clear with the following systems listed above; it will also clear other popular header/y-pipe systems. – SLP, FLP, Hooker and Pacesetters with Pacesetter y-pipe and Texas Speed y-pipe.

Item Will Not Fit- This item is designed to work with long tube header systems and is not designed to work with the factory exhaust system. If this item must be ran with the factory exhaust system it will clear 93-97 V8 factory manifolds and y-pipe but will NOT clear 98-02 models with factory manifolds and y-pipe. This item may not clear the QTP y-pipe, please check before purchasing.

Description- Track abuse, street abuse, or just flat-out abuse, this torque arm is designed to handle it all! Eliminate unwanted traction problems by adding a UMI Performance Tunnel Braced Mounted Torque Arm. This aftermarket torque arm replaces the flimsy weak stock torque arm adding strength, rigidity and eliminating flex. Our torque arm design relocates the front torque arm mounting point off the transmission tail shaft protecting the transmission and preventing damage. A shorter torque arm improves weight transfer on acceleration. General Motors tail shaft mounted design works great for a stock driven vehicle however it is not designed to take abuse. This set-up bolts to existing floor pan holes using 0.500” thick mild steel CNC machined mounting plates and metric grade 10.9 hardware. The complete cross brace is constructed of 0.120” thick rectangular tubing and attaches to the torque arm using 0.250” thick mild steel mounting pivot plates with Grade 8 hardware. The torque arm is attached to the supplied cross brace using an Energy Suspension polyurethane bushing set-up on both the supplied cross brace and torque arm. Polyurethane was chosen as a mounting point to keep road noise at a minimum and eliminate unwanted “clunks” found with other set-ups available. The grease-able polyurethane bushings absorb road irregularities and protect noise from entering the passenger compartment. The rear mounts feature 0.375” thick CNC machined mounting plates and are appropriately drilled to fit your stock rear as well as aftermarket 12-Bolt and 9” Rear-end housings. This set-up requires no welding or drilling and can be installed with basic hand tools; this is a complete bolt-in design.

Chrome Moly- Chrome Moly version uses 1.250″ x 0.095″ 4130 Chrome Moly steel feature 100% TIG welded process. This adds increased strength and reduces product weight, recommended for vehicles running 10.50’s and faster in the ¼ mile.

Rear Torque Arm Hardware Kit- We highly recommend purchasing a new hardware kit if running this torque arm on a stock rear-end, Strange or other similar rear-ends that use a straight through bolt design. OEM torque arm bolts will work however are slightly too short and may not work correctly. If you are running a Moser Engineering 12-Bolt rear-end this kit is not needed, you must reuse hardware supplied by Moser Engineering. This kit however is recommend for the Moser 9”.
