Mini-Tub g-Link Canted-4-Bar Suspension System


Technical Data Sheet
Installation Guide



The Mini-Tub g-Link further broadens the performance application range of our g-Link suspension series to include modern pro-touring builds with substantially larger tire and wheel sizes. The relocated lower control arm position provides approximately 2-3/4" additional clearance on each side of the vehicle when compared to the original leaf spring suspension, with an outside lower axle bracket with of only 39". Offset frame rails are also offered to improve chassis stiffness and maximize clearance. For use with our vehicle-specific bolt-in FAB9™ housing or the vehicle’s existing housing (weld-on bracket installation required).


Adjustable Geometry
Upper and lower suspension link mounting brackets feature multiple positions to adjust chassis anti-squat and optimize vehicle handling. Upper links are length adjustable to set pinion angle and suspension preload if needed. g-Link lower arms are also adjustable for wheelbase variations and precise housing alignment.


Adjustable Shock Mounts
Billet aluminum double shear lower shock mounts bolt directly to the back of the lower control arm bracket and provide 4-1/2 inches of ride height adjustment. The three-position upper shock mount allows additional ride height adjustment, with the ability to provide increased stiffness for improved cornering or softer ride without changing springs.

Offset Frame Rails and Mini-Tub Option

Some vehicles may already have mini-tubs installed. For this reason we offer our mini-tub set and offset frame rails as options for the g-Link Suspension. Our fully-boxed rails provide 2-3/4" additional clearance and a significant increase in strength over modified factory rail channels.

Billet g-Link Suspension

The fixed-length billet-aluminum lower arm gives that added custom touch when peeking through the rear wheels. Make no mistake though, the lighter weight pocket-milled design is plenty robust for the meanest of street machines.

FAB9 Rear End Housings

Due to the increased levels of traction and torque potentially generated by a mini-tubbed vehicle, we highly recommend all installations use our factory-welded FAB9 rear end housings. FAB9s feature 3" axle tubes with an internally boxed gusset area at the outsides of the center section for incredible strength and reliability.
