These Poly Motor Mounts are for the 89 TTA's with PRODUCTION 3.8 V-6s ONLY. They can also be used for engine swaps with prod. 3.8's in other F-body chassis (Camaro/Firebird/Trans-Am). This is a COMPLETE KIT, including new motor mounts, new frame pedestals (frame pads), isolation pads, new hardware, and a custom wrench.
Part # 2001 Poly Motor Mounts are basically the same kit, except that they will bolt up to any GM V-6, production 3.8 and 4.1's, Stg I and Stg II. The biggest difference between these and the #2000 mounts is that these have extra clearance machined into them to fit the Stg I and II and bigger 4.1 blocks, and still fit the production 3.8 blocks. The # 2001's come with our original performance poly bushings installed, designed for higher HP applications. These are designed for daily driving and off road use, and have been put to the test at over 1500 hp with great results.
These come with NEW softer custom poly bushings installed, designed especially for the TTA's. These are designed for daily driving and off road use, down to low 10's in the 1/4 mile, with great results. There will be a noticeable increase in vibrations felt inside the car due to the much stiffer and stronger design. They are designed to keep this to a minimum, but some comfort must be sacrificed for maximum strength and performance. These additional vibrations seem to be most common at idle in gear, and seem to diminish over 1000 rpm. This will vary from car to car, and between stock and rebuilt engines, and also reduces slightly as they "settle in". These are recommended for anyone with the factory 3.8 block, on the street and the track.
The Motor Mounts come completely assembled and ready to bolt on, as do the frame pads, and they fit just as good as they look. These mounts greatly reduce engine movement, transfer power more quickly, and eliminate the need for an engine tiedown strap. They are far more superior in strength than the stock mounts, making them virtually unbreakable. This design also increases the downpipe to frame clearance by approx 1/4", and make the motor sit level. They come with a GM satin black finish, detailed installation instructions, our standard ONE YEAR limited warranty, and new plated grade 8 and 10.9 hardware to bolt up to the block, the crossmember, and for attaching the mounts to the frame pedestals. Also included are 2 special die-cut isolation pads for installation with the frame pads to help reduce any possible vibrations. Also included is a special custom wrench for the hard to reach nuts inside the crossmember.
NOTE: #0199 tool (3/8" hex bit socket) is recommended for easy installation with the motor in the car.
