    How strong is an a-body 8.25 and can you make it stronger?

    Everything has it’s limits. Weight, sticky tires or street tires. They do make 29 spline axles and crush sleeve eliminators for them. In the end, you may be money ahead in the long run with a 60 if you intend to race

    converter opinion question

    At Cudafacthackjob, yes it was slower off the line. I could tell immediately. The weight difference between the two converters, one being a non lockup, the other a lockup which has a clutch inside is a significant difference in rotating mass. Now, if I were to pull that 2500 lockup, I would...

    converter opinion question

    I’d put the 2800 back in. You’ll want the higher stall to make up the difference in rotating mass between a lockup converter versus a non locking. When I converted my 350 s10 from a thm 350 with a 2500 b&m converter it was quite a burnout machine. Changed to a 700r4 with a 2500 stall/lockup...

    About to build my diff- What limited slip?

    I run an eaton tru trac in a 9” under my s-10 with a decent 350. Smooth running on corners but stomp it and both tires always break loose.

    8 1/4 diff

    Somewhere in the drivetrain forum there is a lengthy thread on this. Several members did the swap with the original housing going from 2.45 to whatever they wished. Search it and read up. Just make sure you use the right gears with the right carrier

    8 1/4 Rear Axle question

    27 spline to 96. 97-04 is 29 spline. Moser I believe still makes axles for it.

    This why you run a blow proof bell housing and scattershield

    My 350 s-10 has sfi flex plate and all arp hardware holding it to the crank and the converter to the flex plate for that very reason! Damn I hope that driver was okay

    rear- end ID

    The two bolts on top are probably for a pinion snubber. Only way to check for suregrip is jack the axle up and spin a tire. Both spin same direction, suregrip. One spins opposite direction, open.

    6 Speed Slant Six

    Interesting. With that low 1st gear and the axle gears you wanted, that could pull even a 28"-29" tire if you wanted. It would kill a 26" off the line

    Rear

    On the exhaust you could just change the collectors and go to a larger size exhaust system. How large is the collector on the header size? If you do increase your exhaust system, I would tune your carb then after as it will make your tune a little bit lean.

    Rear

    Curious to see what your car would run in the quarter right now as is. E.t and mph. If it ran high 13's for a 318 with 3.23 gears that's actually pretty respectable. Still think that 2" exhaust system is too small and there is probably a lot of tuning left to be discovered that can make a...

    Rear

    Anything taller than a 26" tire with uour gears may be nice cruising on the highway but will bog your motor down on off the line acceleration with your current setup. Initial and total mechanical timing are very important for your torque off idle and can have a big effect

    Rear

    2000 stall is very mild, a 2800 would be an improvement. What is your timing set at? Initial, mechanical and at what rpm does it come in? Tire size? 2" exhaust isn't that great, 2.5-3" would allow a lot better breathing ability and accomodate more cubic inches if you wish in the future...

    Engine RPM at Hiway speed

    How tall is your tires and what gear tooth installed in the trans? Use the search and there are several gear tooth charts posted on this site. If the speedo gear is correct to the chart for your tire size and axle ratio, i'd look at the trans. Could be stuck in second as stated previously or a...

    Differential replacement.

    Www.doctordiff.com has them new for about 350.00 your axles should be 27 spline, 29 spline came out in 97.

    7 1/4 worth rebuilding?

    Understandable, the 8.25 will be cheaper and they did come in a bodies factory. Will have to have your driveshaft shortened with either axle swap. The 7.25 has a 2.5" axle tube, the 8.25 and 8 3/4 are 3" tubes, so different u-bolts to clamp it to the leafs and shock mount pads are needed...

    7 1/4 worth rebuilding?

    8.25 or 8 3/4 would be better. More parts, better gear selection available

    Anyone ever tried a Lock Right diff in a D 60?

    I didn't have to remove the carrier on my stock 8.25 with open differential. Just removed the spiders.

    Anyone ever tried a Lock Right diff in a D 60?

    Accelerating from a stop on pavement can be a little jerky if it was unlocked. It's the sudden lockup where the jerk comes from. In the mud, not sure you would even notice

    Anyone ever tried a Lock Right diff in a D 60?

    The jerking of when they unlock and then lock. It depends on howyou accelerate from a stop as well as how your tires grip has a lot to do with it

    Anyone ever tried a Lock Right diff in a D 60?

    I ran it for 8 years in my daily driver. 2003 dakota 2wd. A little over 150,000 miles with that power trax. Just got tired of it was all. When I had the oem limited slip installed, I also had the ring/pinion gears changed as over time the jerky motion of the locker put a little extra wear in...

    Anyone ever tried a Lock Right diff in a D 60?

    They do unlock during turns as advertised. Just have to be mindful during slick conditions to avoid fishtails in ice/snow. For offroading it should be good.

    Anyone ever tried a Lock Right diff in a D 60?

    If the power trax lockright, I ran one of those for years in my dakota. They do work, however they are jerky and noisy. I have heard the changed the angle of the teeth a bit to reduce the noise, but I don't know anyone who has one currently. I changed it out for a oem trac loc

    Lockers for dragracing?

    Can't comment on the racing aspect, but I ran a powertrax locker for about 8 years in my Dakota. They do work, however they are a bit noisy and jerky. Tire grip has a lot to do with it as well

    Will the rear axle fit?

    It's true you can find them in salvage yards, but for the price of a new one with bearings from a trusted source like Doctor Diff, it's hard to beat the price. And by upgrading his oem axle, no fitment issues, no shackles to relocate, no special offset rims to deal with.

    Will the rear axle fit?

    Doing the change with the gears at the same time would be ideal. That way you'll only pay for labor once. Price for that is unknown. Find a drivetrain shop who does rear ends regularly. If you're 8.25 is the original, it's a 27 spline unit. The 29 slines didn't come out till 97

    Will the rear axle fit?

    Limited slips aren't that expensive. Www.doctordiff.com oem 27 spline trac loc for 350.00 with new bearings and seals.

    Will the rear axle fit?

    Why not just swap the 2.76 open diff for a 3.23 suregrip in the 8.25 axle? The 8.25 is stronger than given credit and if you swap the 8 3/4 in, you'll need to have the driveshaft shortened and balanced.

    Axle ratio

    Put the rear axle on jack stands and turn the tire one revolution and count how many times the pinion yoke turned. That will give you a ballpark idea of the gear ratio and then use the chart to order the approriate speedo gear
