Description

Description

Currently still in development!!!

 

4-link suspension for full-size Chevy/GMC truck.  Designed and tested in-house, our engineered kit replaces the factory leaf spring suspension. The JSM 4-link kit is properly set-up to reduce the effects of body roll and can be adjusted to improve traction, ride quality and braking.  This kit is a mostly bolt on kit, with welding only required on the brackets for the axle.

Multiple holes exist in order to adjust the instant center for optimum traction.  Be sure to read our tech topics if you need more information.  The panhard bar is adjustable also allowing for different roll centers.  We use Johnny Joints on 1 end of each 4 link bar to allow for less binding even though it cost a bit more we feel it is worth it.

Options include our 4-link kit with or without shocks & springs.
We pair our 4-link with Viking Warrior double adjustable shocks and springs for ultimate performance.  Upgrades to the shocks are available with custom valves, remote reservoir, etc.

*Contact us for special pricing for shock upgrades, including magnetic ride capability.

Viking Warrior Shocks

All Viking Warrior shocks are digressive valved and double adjustable allowing the user to independently adjust compression and rebound with separate adjustment knobs. This provides significantly more tuning capability than single adjustable or non-adjustable shocks.  A lightweight aluminum twin tube design with clear anodized finish makes Viking the perfect shock for daily driven street and track use. All Viking shocks are made in the USA. Springs are sold separately.

SyTy Front Coilover Spring

2.25" spring for JSM/Viking Coilover shock.  Requires machined cups which if you bought the shocks from us we do for you.   Please put in the note what spring rate you want. Recommended for SyTy is 450 or 500 lb springs.   If you have a heavy or lighter vehicle from stock you may want to go up or down.  The 450-500 range we have found fits 95% of the trucks out there. Word of caution:  We have found people tend to go to high of a rate.  The higher rate spring will decrease ride comfort AND handling.
