New to the LS1 world is Harland Sharp offering a brand new set of roller rockers. They fit under the stock valve covers. They have full rollers that can be rebuilt if needed. Bodies are completely machined from billet aluminum. Harland Sharp has been building race roller rockers since 1960 so they are not a new company just new to LS1`s. We also have good pricing for other vehicles as well. For a look www.harlandsharp.com I will also post pics soon.

Adjustable and Shaft rockers available soon.
We will run these prices till 1-1-04
Harland Sharp LS1 Roller Rockers $285.99 a set
Harland Sharp LT1 Roller Rockers $245.99 a set

Have a great day Nate

 

I'm sorry but I looked everywhere on their site and could not find anything listed for the LS1. Please post a direct link to the page. $285 sounds awful cheap for LS1 Shaft Rockers!

 

guess it aint listed yet
i didnt find anything either

 

Finally, a parts supplier who is not charging a premium for LS1 parts. Put me down for a set when they are available.

Are these just stock replacements, meaning they bolt to the factory rocker centering strip?

 

Sorry they are so new they have not got them on the site yet. And I thought that was the point to be cheaper?

White-Hawk they are available the adjustables are not yet available.

No these are setup like the Yella Terra`s 2 are attached to one another and they sit on pedistals.

Just got off the phone with a guy at Harlands. He gave me some good info on the rockers. They are a direct replacement for the factory rocker arm, Shaft mounted, fit under a stock valve cover and are currently being used in a 620RWHP LS1 drag car with out problems. They are a moddified version of the SB chev rocker arm so they have a good history behind them. He also said that the ONLY weak point that he could ever see in this system in the 8mm bolt used to hold the rocker in place. He said that he would have no problems machining these out to a 7/16th if you wanted to do a bolt upgrade, but it would require you to have the heads machined.

Adjustables will be out in the future and they will require a taller valve cover and will be based on the Jesel design.

Nasty N8, put me on the list for a set.

 

Could you use some thread lock then on the bolts? Sounds like a good deal none the less

 

With these being roller tips, would a H/C car pick up any horsepower over stock or are they mainly for peace of mind/quieter operation by eliminating the stock valvetrain parts?

 

NataSS thanks for the info give me a call and we can get your order in.

Sure you can use lock tight or a thread sealer if your heads have the bump taken out.

I have seen 10hp on most cars with roller rockers they claim 15-40hp increase.

where can we buy them at? I think I'm gonna be a test dummy for my local f-bod club

 

Yes you need to be the test dummy for us lol

 

Just give me a call and I can put your order in.

Nate

 

If you placed a order when have you been told of there ship dates?

 

"factory replacements" meaning 1.7's, right?
If so, I'll definitely consider a set in the near future

 

will these fit under 98 valve covers?

 

I would like to know this as well, if they do i am definately in for a set.

 

do they have 1.6 ratio?? and if so when will they be shipped......i am ready to buy


jimmy

 

What is the price going to be after the 1st of the year?

 

Shipping should be any day now.

1.7 is stock ratio and thats what they make them in. Why would you want to go down to 1.6 ratio?

As far as 98` I am not sure haven`t had a set mounted on one yet. They are much smaller than the Yella Terra`s so even if they don`t clear than it will be conciderably less clearancing to do. It is not too difficult to make the Yella`s fit so I see these being easy.

The regular retailis $330.99

Thanks Nate
