Do I need leaf spring shims?
Do I need leaf spring shims?
The rear depends on how it’s been set up. If it’s running a transfer case drop and a shim in the rear then you need the shim. If it’s running a SYE with cut and rotated spring perches then you shouldn’t need a shim.
How thick is a 2 degree shim?
Note: 2 Degree – Shim thickness at tall end is . 435″ and . 268″ thick on the short end.
How thick is a 6 degree shim?
The steel degree shims are designed to change the pinion or caster angle on a leaf sprung vehicle. These shims are 2.5” wide, and work with 2.5” wide leaf spring packs.
What are pinion angle shims?
Axle shims are thin pieces of metal that are placed between an axle and a leaf spring to adjust the pinion angle of the vehicle’s axle. Typically, the pinion being set at a slight downward angle at the drive shaft yoke is best.
What are leaf spring shims for?
Steel shims to go between your leaf springs and your spring perch. These are used on leaf spring vehicles in order to adjust pinion angles and achieve proper drive line geometry.
How do you set pinion angle with leaf springs?
With leaf springs you should set the pinion 3or 4 degrees down from the transmission angle. This will allow for pinion wind up unless you are using attraction device (then the pinion angle would be less). Don’t worry about the opposite but equal numbers so much.
What degree should pinion angle be?
According to Currie, the average car crafter should strive for between 1 and 3 degrees between the tailshaft of the transmission and driveshaft, and 1 to 3 degrees between the driveshaft and pinion. Furthermore, the two angles should be nearly equal (between 1 and 3 degrees), but always opposite (see crude diagram).
What do leaf spring shims do?
What are Axle degree shims for?
Axle degree shims are ideal for Add-A-Leaf and Leaf Pack installs to minimize or eliminate rear drive line vibration. Degree shims are perfect for 2″ to 3″ rear lift.
Can wrong pinion angle cause vibration?
Pinion angle is one of the most important considerations on a lifted vehicle, but sadly it is often overlooked. The wrong angles can lead to horrible drive line vibrations, as well as premature failure of U-joints, driveshafts, pinion bearings and even transfer case output bearings.
Should pinion angle be up or down?
The driveshaft should be sloped towards the pinion so there is a little angle between the two. It’s easier to imagine the driveshaft and pinion perfectly parallel or inline with each other, then with the pinion tilted up compared to the driveshaft to visualize what he’s saying to avoid.
How thick is a 4 degree axle shim?
Note:4 Degree – Shim thickness at tall end is . 551″ and . 191″ thick on the short end. Note: 2 Degree – Shim thickness at tall end is .
Does ride height affect pinion angle?
As the ride height is lowered (suspension is compressed, or in bump, as shock tuners call it), the pinion angle will change. This occurs because the upper arms are shorter.
How do I know if my pinion angle is off?
So what symptoms would lead you to identifying bad pinion angle? Drive train vibration at speed, wheel hop and universal joint fatigue/failure are all good indicators. These things can come out of no where with suspension bushing failures, engine and transmission mount failures or even leaf spring fatigue and wrap.
