Also worth considering is that a locked rear does NOT want to turn. I've had great concerns about breaking an axle so I leave all our machines as either Open Diff 8 speeds or Limited Slip Differential 6 speeds. 1 hour ago, Pullstart said: I think people have done 8 and 10 pinions. 8 pinions I've seen. 10 I haven't. IMHO it's pointless to weld or lock a 10 pinion because it's already a Limited Slip Differential. Locking up a 10 pinion could lead to easier damage than an 8 pinion because the pinions are smaller and the end plates are not as strong. 2 4 Share this post Link to post Share on other sites
Pullstart 62,852 #7 Posted April 16, 2023 Obviously, this is not a guarantee that it’ll perform or last as you expect. These are not trucks and are sometimes treated as such. Individual results may vary 3 2 Share this post Link to post Share on other sites

If it's a 10 pinion it might not lock that way. Only 8 pinion diffs work that way and each set in sequence needs to be opposite. Share this post Link to post Share on other sites

Its an 8 pinion. so your saying not every other one. but every other set? 1 Share this post Link to post Share on other sites

To lock it, have two opposing sets of two headed the same direction. I have an 8 speed open on the bench so I can get you pics tomorrow morning if it helps. 1 Share this post Link to post Share on other sites

Toby Stockman 70 #14 Posted July 20 yep i locked my pullers done a 8 speed and a 3 speed works great but you will go through tires like you wouldnt belive even on dirt/grass Share this post Link to post Share on other sites
Lee1977 6,659 #15 Posted September 14 Those that speed them up and trail ride through the woods weld the differential. One reason is traction the other is to have brakes on steep hills. Braking one wheel will lock and the other will freewheel 2 Share this post Link to post Share on other sites

Locking up a 10 pinion could lead to easier damage than an 8 pinion because the pinions are smaller and the end plates are not as strong. Not necessarily. Limited slip takes half the power of the wheel slipping and sends it to the other wheel. It is very easy to get just as stuck with and LSD as you would be with an open rear. Half of zero is still zero afterall. How the power transferred also makes a difference in how well it works. Clutch-style LSDs tend to be more susceptible to that kind of issue. Torsen units, which more closely resemble the 10-pinion rears, are better. They have a lower torque bias and so if you have one wheel standing still and the other spinning fast enough you get get a Torsen to act like a locker. 1 Share this post Link to post Share on other sites
RandyLittrell 3,877 #17 Posted October 7 I pulled garden tractors for a long time and none of the pullers I pulled with locked the diff. You really don't need it, I never had just one tire spin out. Randy 1 Share this post Link to post Share on other sites
