Answer This Question

Q:

Looking to upgrade the axles in my '70 Chevelle. Car is cruised with occasional throttle fun and 1/4 mile passes. No transbrake, no slicks. Nitto drag radials and foot brake only. How much horsepower and torque will these handle reliably?

Asked by FRANCISCO on June 09, 2018

A:

I bought a pair of these for my 71 Monte Carlo SS454 drag car. Same exact P/N for 70 Chevelle. They can take what you've got! I have a 468 with 13:1 Compression, over 600 HP and use a trans brake with a 5,000 Stall converter and slicks at the dragstrip, no axle problems ever!

Awesomely beefy axles!

Summit RacingSummit Racing Verified Purchase

MSR-A123003
These axles are much, much beefier than the stock axles in my GM car 12 bolt rear end. They are well machined and the splines mate up perfectly to the carrier. Visually, the axles are noticeably larger in diameter and the flanges are much thicker than stock. However, there are a few small issues to be aware of if you are considering these. First, as mentioned in the previous review, these are approximately 1/8" wider than stock axles. This may cause brake alignment or wheel fitment issues depending on what brakes you are using and how tight your wheels are to the wheel wells. My solution was to shim out the backing plate on my 98-02 F-body rear brake swap to maintain proper caliper alignment, the same could be done for a drum system. Another minor issue occurs when using ARP 1/2-20 wheel studs. Because the ARP studs are not threaded all the way up, you will either need to chamfer the back sides of the holes in the flange or use a hardened washer as a spacer under each bolt head. Chamfering the holes will slightly reduce thread contact while the added thickness of a hardened washer could cause the heads of the bolts to interfere with your brake system. Last, I had to chase a few of the holes to clean out the threads before installing the bolts. Not a big deal, it only took a few minutes. Given these minor issues, I would still highly recommend these axles to anyone looking for an upgrade in a street driven car that sees track time on weekends. ...read more

Nice but wrong

Summit RacingSummit Racing Verified Purchase

MSR-A123003
They looked like great axles, but we're .150" too long and I had to send them back due to interference with disc brake kit. Didn't get full refund because I had pressed in studs, so they were used.

Rear Disc Brakes

Summit RacingSummit Racing Verified Purchase

MSR-A123003
These axles were longer than than the factory axles. Maybe 1/8th of an inch. I have rear disc brakes on my 69 Chevelle. I could not install my brake calipers with pads over the rotor. I contacted the disc brake company and it was a simple fix. I needed to change out the brake caliper bracket shims. I wish I knew ahead of time to have been ready for the install. ...read more

I order these axles with the intention of rebuilding my diff but decided to go with a 9 inch. Summit returned both axles, and the process was painless. I will continue to use Summit. Thanks Summit
