Easiest way to measure your sway bar for when you are ready to order bushings is to take an adjustable wrench and slip it over the bar and tighten it down until it just makes contact. Then remove the wrench and measure the distance in between with a tape measure.
Q: When should I fully tighten the suspension after replacing or working on my control arms, trailing arms, shackles and hanger bolts?
Tighten the bolts with the full weight of the vehicle on the ground after the suspension has been bounced up and down a few times to allow it to travel through its full range of motion.
Q: What are the advantages of running the PST tubular upper and lower vs. stock control arms on my muscle car?
PST’s tubular control arms are precision CNC manufactured, equipped with smooth operating Polygraphite bushings, heavy duty offset cross-shaft for increased camber adjustment and the need for less shims when aligning. Control arms are 100% tig welded and bolts in stock location.
Yes. Any weight reduction from factory parts will affect ride height.
Using drop spindles is the best means of lowering your muscle without sacrificing ride quality. Lowering springs can be used but are not recommended for drops past 2”.
Yes. Any time you work on the suspension system and after adjusting the ride height, it is necessary to check and adjust the alignment of the vehicle. By lowering the ride height, some camber and toe may be affected.
It is best practiced and highly recommended that the polylube that is provided with the Polygraphite® bushings be used. Apply liberal amounts of polylube during installation. If polylube is unavailable, good quality white lithium grease can be used.
To identify the left and right arm place the arm in the control arm pocket. Then take note at what angle the ball joint stud is pointing. When properly placed the ball joint stud will be pointed down and angled back towards the rear of the vehicle
When installing PST’s Mopar torsion bars make sure to remove the upper control arm bump stop to allow the suspension to drop fully down. Also back your adjuster all the way off prior to installing into the lower control arm and anchor point.
General rule of thumb when installing any caliper during a disc brake conversion is to make sure that the bleeder faces upward to allow any air to escape when it comes time to bleed the system.
