Let’s discuss the question: how to set pinion angle on lowered truck. We summarize all relevant answers in section Q&A of website Activegaliano.org in category: Blog Marketing. See more related questions in the comments below.
What should I set my pinion angle at?
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).
Does pinion angle change when lowering a car?
Yes, lowering the rear suspension changes your pinion angle and affects how your LCAs respond (squat) under hard acceleration.

Do lowering blocks affect pinion angle?
Depending on how low you go the pinion angle will remain the same with 1-3 inch blocks. 4″ blocks will have a angle. When using blocks the only angle that changes is at the transmission . This can usually be corrected with shims under the transmission mount pad to crossmember.
Does ride height affect pinion angle?
The ride height has no bearing on the engine angle, but it does on the pinion angle with a live rearend.
How do you know if 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.
How do you set pinion angle with leaf springs?
For example, if you have a rearend angle of 5 degrees from vertical nose up and the driveshaft is angled up at 3 degrees, you have 2 degrees of positive pinion angle. If this was a leaf spring car, you’d need to change the angle by 7 degrees to get 5 degrees of negative pinion angle.
Can wrong pinion angle cause vibration?
In your case, it appears that the pinion is operating at an intersecting angle to the driveshaft. This will cause a vibration at speed.
How do you calculate driveline operating angles?
To calculate operating angles, you must add or subtract the component angles– that is, the relationship of the operating angles between the transmission, driveshaft and the differential, on each side of the driveshaft (drive and driven ends).
Do lowering blocks affect handling?
Your vehicle won’t handle rough roads well.
Since lowering blocks create a lower clearance for cars and trucks, you won’t have the same navigational power to drive wherever you want. Anything that is rocky or rutted could grind your undercarriage, as could entryways with a steep grade.
What do lowering blocks do?
Axle-Over Only
Before lowering blocks will work, you must make sure that your axle is on top of the leaf springs. If not, then the lowering blocks will in effect become lift blocks, because the idea is to raise the axle up, putting the wheels further into the wheel wells, which will lower the vehicle.

What is a lowering block kit?
Lowering block kits are manufactured of high quality extruded aluminum and come complete with blocks, U-bolts, Nyloc nuts and washers. The extruded aluminum process yields higher strength ratings when compared to cast or steel lowering blocks.
How much driveline angle is too much?
Ideally, both driveshaft-operating angles will be 1 to 3 degrees. Anything over 3 degrees at the rear axle will shorten your universal joint’s life and could create vibration. If your angle is larger than 3 degrees, you must make sure not to exceed max driveshaft RPM as shown on this Spicer table.
How do you adjust driveline angles?
- Place an angle finder on the bearing cap and take note of the reading.
- Rotate the driveshaft 90° and repeat step one.
- Find the difference between the two readings and this will be that u-joint’s working angle.
Does tire size affect pinion angle?
Tire size does not affect the angles. If you put larger diameter tires in the rear, the rake of the car changes, so does the relative angles with respect to true level.
How does pinion angle affect traction?
A wrong pinion angle that binds things up will cause traction problems and if the angle is changed so that it would relieve the binding then that would actually change the way the cars hooks, but that is the only case where a pinion change with out changing anything to do with the suspension would have any affect.
What is the best pinion angle for drag racing?
SC is correct, for drag racing you want anywhere from 2-4 degrees dip in the relation of the pinion to the driveshaft, I do most performance street cars the same way, however for your everyday driver, You set up the rearend to have the same angle as the crankshaft/transmision.
Does pinion angle cause wheel hop?
Setting pinion angle keeps you from destroying driveshafts, ujoints, and pinion bearings. Wheel hop is caused by what the others have said about the susp moving(spring wrap) and traction of tires. You need the susp to keep the pinion angle realtively the same, and in turn it stops wheel hop also.
What degree should the rear differential?
“The goal is you want the rearend angle opposite of the transmission. In most rear wheel drive cars the transmission angle points down. So you want the rear axle pointing up at the same angle to get a net zero angle. If the engine/trans points up then the rear axle should point down.”

What is pinion angle in drag racing?
We want the two working angles to be within a half-degree of each other and as slight an angle as possible, less than three degrees is normally recommended in drag racing.
How do you adjust pinion angle with ladder bars?
Using the bottom adjuster on the driver side ladder bar, adjust the pinion angle 1-3 degrees below the driveshaft angle. 3. Using the adjuster on the passenger side adjust the ladder bar back up until the bolt goes back into the hole and through the crossmember freely.
