Rocky Mountain Parabolic Springs are manufactured to ISO standards. These rugged springs have advanced design features perfected over many years of supplying parabolic springs to leading truck manufacturers. The individual spring leaves are tapered, heat treated, and stress peaned under load for increased strength. Bending stresses in the material are evenly distributed along the length of the leaf. There is generous contact area on all wear points, and stresses caused by drilling are minimised by having the guide straps positioned near the end of the leaves. The clamp area under the axles is kept absolutely flat to prevent pre-load. Spring bushings are a full 1¼ inches diameter for greater flexibility and this increased curvature reduces stress in the spring eyes. Springs are supplied in pairs and packaged with correct ‘U’ bolts, nuts and washers needed to complete the installation.
Fitting ‘Rocky Mountain’ parabolic springs will raise the loaded ride height of your Land Rover by at least one to two inches when compared to stock springs.
The use of extended shackles to raise the ride height further may create stability problems and drive line problems and is not recommended. Where extended shackles are used (as in military Land Rovers) the extended axle buffer mounting must be retained to prevent over-stressing the springs in maximum compression.
NB: Fitting extended shackles without extending axle buffer mountings will invalidate your warranty.
PARABOLIC SPRINGS will make a very significant improvement to your Land Rover and are probably the greatest single modification worth making to enhance enjoyment of the truck for you and your passengers.
