Tru Turn Package - 1978-1988 GM G-Body by Ridetech
TRUTURN - Musclecar Steering Components
An upgraded control arm system that includes StrongArms, tall ball joints, delrin bushings, and tie rods
What will this system do?
The TruTurn system resolves bumpsteer and camber gain issues... the tires now lean INTO the turn.
- Taller upper ball joints to increase camber gain.
- Integrates with OEM spindles.
- Increased caster settings.
- Optimizes bumpsteer to under .065" through 5" of suspension travel.
- Includes upper and lower StrongArms, outer tie rods, and billet tie rod adjusters.
What says “performance” more than a set of tubular control arms! After all of the time and effort expended on your ride, you definitely can’t let your stamped OEM control arms detract from all that work. Finish your suspension off with these new tubular control arm systems from RideTech. Built with all of the care and experience you have come to expect from us, these tubular control arms are a precision engineered solution for ShockWave® installation, ball joint binding, and frame clearance issues that can haunt some vehicles. When you combine the performance benefits with the elegant design of these arms, there is no question.... You want these.
Development - StrongArms™ are developed by RideTech® in Jasper, Ind. on an actual running, driving vehicle. This allows us to properly address ALL fitment and performance issues. It also allows us to document an installation, demonstrate the installation to our sales techs and dealers, and allows ongoing evaluation of the performance of the StrongArms™
Design - We think the best way to design any component is to keep it simple. That is why Strong Arms™ are designed with as few components as possible. We have a new 4 axis tubing bender that allows precise, repeatable bends that no other machine can achieve. We can create elegant tubing bends that would otherwise require several separate welded components.
Components - We have worked closely with Moog, a major manufacturer of OEM ball joints, to ensure that the proper ball joints have been selected for the Application... a compression style unit in a compression application, a tension ball joint in a tension application. Proper poly or rubber bushings are selected based on application and the type of driving or racing that is anticipated.
Geometry - Geometry of a suspension starts with the position of the frame mounts and the height of the spindle, not the shape of the control arm. However, there are a few small things in control arm design that can make a big difference in how a vehicle drives and performs.
- We create extra caster potential by adjusting the fore and aft position of the ball joints. At the same time we make sure the wheel is properly positioned in the wheel-well so your new 18" wheels fit like they should!
- The balljoint camber travel is re-centered to accommodate the new lowered ride height so the ball joint doesn’t bind during extreme suspension movement.
- The perimeter of the StrongArms is contoured to allow maximum wheel clearance and turning radius.
- All shock mounts, airspring mounts, and swaybar mounts are integrated into the design so you don’t have to finish the engineering in order to enjoy your ride!
StrongArms™ are optimized to allow proper camber adjustment at your new lowered ride height without using a large stack of shims.
All STRONGARMS include ball joints, and bushings. They are bolt-on: ready to install!
Frequently Asked Questions
Do I have to modify my oem subframe?
No modifications are necessary at all.
Can I use my existing OEM spindles with this system?
Yes, the G-Body Tru Turn package was specifically designed to work with the OEM spindle.
What is "bumpsteer" and why should I be concerned about it?
Bumpsteer is a term that refers to the control arms and the steering linkage moving in different arcs as the suspension moves through its travel. When this happens the tie rods will move the steering arms [and therefore the wheels] in directions that the driver does not intend. This leads to an "uneasy" feeling car. Some OEM cars [especially older musclecars] can have a lot of bumpsteer...as much as 1"! Imagine the toe setting on your car changing unpredictably as you go down the road! The Tru Turn system nearly eliminates this situation...the bumpsteer is 0" over the entire 5" of suspension travel. This leads to a very stable and comfortable feeling vehicle.
What is camber gain and why should I be concerned about it?
Camber gain refers to the rate of camber change the spindle will see through the range of suspension travel. With most OEM cars [especially older musclecars], the OEM suspension geometry will lean the compressed wheel OUT when turning. With the TruTurn suspension the compressed wheel will lean INTO the turn, keeping the tire squarely on the ground thereby offering more lateral grip AND offering a more stable turning experience.
