jefe de jefes Posted September 2, 2010 Report Share Posted September 2, 2010 I also ordered 8 of these......... Dorman #610-403 – ’93-‘95 J30 (front) & ’93-’98 Quest (rear) Type Serrated Stud / Thread M12-1.25 / Knurl Dia. 12.90mm / Length 45.5mm / Shoulder Length 15mm Ill be swapping them out Sat. & ill get comparison pix. Yeah, let us know how these work out for you. I'll be needing to purchase some studs real soon for my strut swap. Not having to buy new lugnuts would be great! Quote Link to comment
Pacific coast Datsun Posted September 2, 2010 Report Share Posted September 2, 2010 Jefe i sure will. My issue is with the revolution rims im switching over too. They require a deep shank lug nut & longer studs up front [running 82 280 ZX struts]. The rears are fine [stock 510 studs] seeing as they're 41.5 mm long. One possible issue will be that the stock ZX studs have a knurl diameter of 13.00 mm & the 510/ZX rears [longer studs] are 12.83 mm. The Quest studs are 45.5 mm long & the knurl is 12.90mm which should be a tighter fit. Pics & info to come. Quote Link to comment
Pacific coast Datsun Posted September 3, 2010 Report Share Posted September 3, 2010 Ok got the new studs in today. I went with these....... they are 45.5 mm long. Look at them compared to stock ZX studs [32 mm]... I put some grease on the base of the stud then used a stock lug to tighten w/ a ratchet until it was tight....... then i put the hub behind the rim & used the ratchet again to tighten the lugs until the new studs sat FLUSH against the back of the hub. Doing it this way will ensure that they are installed straight...... Im using a deep shank lug nut BTW on these rims & now i get 9 full turns on the lugs. Much better & safer now all for $20 & a few hours of labor. Quote Link to comment
jefe de jefes Posted September 4, 2010 Report Share Posted September 4, 2010 Nice! Thanks for the info and taking the time for pics. You purchased them through kragen right? Quote Link to comment

YW Jefe yeah got em @ O reileys / Kragen. They had to order them but it only took 1 day to come in. Ill add that while you have the hubs & rotors off it's a good time to inspect the bearings & at the very least repack them w/ grease. Quote Link to comment
jun Posted September 30, 2010 Report Share Posted September 30, 2010 Thanks for the awesome writeup PCD! I need to do this to my ZX fronts as I want to run a 1/4" spacer to bring out my SSR's ever so slightly. Man I didn't realize those ZX studs are so short. I was ok on the rears (stock 510 studs) but the fronts, I took one lug off and realized this wasn't going to work :lol: Quote Link to comment

This info is PRICELESS & if it wasnt posted in this thread I'd be totally lost in regards to my wagon studs. Quote Link to comment
butcherboyjc Posted September 30, 2010 Report Share Posted September 30, 2010 I just ordered longer wheel studs. When I removed the studs from the 280zx hub I measured the knurl diameter and it measured .505" so the closest less inexpensive studs are .509" knurl diameter that I found in Summit. ARP 100-7708 set of 5 studs knurl diameter .509" and underhead length of 2.5" for $13.25. I will post some pics when I press them in. Quote Link to comment
mklotz70 Posted September 30, 2010 Report Share Posted September 30, 2010 I had posted this info in the 1200 brake upgrade thread I'm doing....but I like the title on this thread...I think people will find the info here more easily... Here's what it looks like mounted...I don't have the length difference on hand. Quote Link to comment

Spades Posted October 2, 2010 Report Share Posted October 2, 2010 Ok got the new studs in today. I went with these....... be careful with those. I used to love Dorman but lately they have been using cheep Chinese metal, the lugnuts and studs we have bought recently from Dorman have stripped out easily compared to their products of yesteryear. I bought Raybestos studs for my wagon...the OEM Raybestos studs were good quality and longer than the original factory studs on my 72 wagon. P.S. ARP makes amazing fasteners, I can't say enough good things about their head bolt and stud kits...only problem is most of their products are usually pricey :( Quote Link to comment

I almost went with ARP studs but i was on a time & $$$ crunch & didnt have time/$$$ to go buy new lugs. Well that & my wagon is a granny car that hardly ever sees the freeway. butcherboyjc- those should work fine, theyre double the length :D Can you share what lug you end up going with please...? TY Quote Link to comment
butcherboyjc Posted October 2, 2010 Report Share Posted October 2, 2010 M12x1.5 So if you use the arp studs you need to get new lugnuts. I found that the 1.5 pitch is more common in the auto parts stores. Quote Link to comment
Spades Posted October 5, 2010 Report Share Posted October 5, 2010 The Dorman studs should be ok, I am running Dorman lug nuts cause I haven't found anything else that will work with my wheels from my suppliers. I just recommend removing and installing them by hand, don't use a air gun cause they strip easily. Quote Link to comment
Pacific coast Datsun Posted October 5, 2010 Report Share Posted October 5, 2010 "I just recommend removing and installing them by hand, don't use a air gun cause they strip easily. " Mine came out easily..put the lug on a few turns & gently tap w/ the mini sledge & out they came. Install was done using a wratchet / socket & a bit of grease on the knurls. Quote Link to comment

I picked some up and they are pretty long! All I need now are the longer bolts for the bumpsteer spacers. I couldn't find the Mcmaster Carr catalog at work though. Quote Link to comment
dennis Posted October 23, 2010 Report Share Posted October 23, 2010 Thanks for the info Dennis. I picked some up and they are pretty long! All I need now are the longer bolts for the bumpsteer spacers. I couldn't find the Mcmaster Carr catalog at work though. McMaster Carr doesnt have any bolts with a grip length in that size. If you measure the RCA on the LCA then that is what your grip length will be then measure your flange on the struts for your thread length or just add that much in grip length to equate the size of a RCA and add the stock fasteners. I would give you my info on bolts for my RCA's but I probably wont get them for at least a week. The other parts are on order from there supplier and my entire shipment will not be sent out till it is all ready to go. As far as lugs I am just running ARP 12m X 1.5 and new lugs since I am going to have to run a 15mm spacer and even 50mm lugs would not give me enough thread for a ZX hub/15mm spacer and rim.

jefe de jefes Posted October 23, 2010 Report Share Posted October 23, 2010 I'm going to take some measurements tomorrow and I'll hit some local hardware stores. If that doesn't work I'll probably just hit up t3 and have them send me some. Quote Link to comment
jun Posted October 23, 2010 Report Share Posted October 23, 2010 Here are the images wit the new studs. butcherboy, did those go on without a problem? I going with these, as my brother has an extra set of 1.5 superfancytuner lugnuts that he's giving me. And I like the fact that I'll never have a problem with coming up short on threads, ever :D Quote Link to comment

I have the same studs ready to go right now. I doubt very seriously you would have to bore out the hole any further, the stock knurl is .505 and these are .509. Quote Link to comment
jun Posted October 27, 2010 Report Share Posted October 27, 2010 Any feedback, Dennis? or Butcherboy? I don't have a press so I'd be using PCD's old lugnut method of installation :D Quote Link to comment
