Let us put our experience to work in your Toyota.
From Rock Crawling to Desert Racing we can build it right!
At DOA we focus on drivable, useable, dependable performance. You cannot swim without going in the water, and you cannot provide road and trail-worthy components without being a user yourself. Before you spend your money on any performance additions, consider the source, and understand the difference between a business that simply sells, and a business that sells from real usage, and real world experience. We all claim to "test," but who do you see on the trails? And who provides real assistance through applicable knowledge? DOA does!
Jeff Moskovitz's DOA-built 22RTE, shown above, is just one example of the work that we do. For more info on this motor, click here.
DOA Racing's 3.0 Head Stud Kit, $345.00
This stud kit is an excellent, affordable upgrade to any 3.0 Toyota engine!!
The factory head bolts are less than acceptable in OEM situations, and are in no way acceptable for any rebuild, performance or otherwise. The OEM torque value of 33lb. + 90ƒ + 90ƒ yields almost a 12lb. variance, and is a serious contributing factor in 3.0 head gasket failures!! This is a fact.
Factory head bolts should never be reused, and this is a major monetary issue, especially when a gasket has failed.
DOA's head studs can be reused repeatedly, have zero torque variance, and aid considerably in head gasket seal!!
This is a "win, win" for the rebuilder and the consumer. DOA's head stud kit costs less than OEM head bolts, and they offer consistent torque yield, and this means a greater seal, period!!
Each kit includes 16 studs and 16 grade 8 nuts. [Note: the factory washers are retained and reused with these studs.]
Adjustable Timing Gears
We now have adjustable timing gears for the single, or dual row timing assemblies, with a 10* adj. Gear cost-105.00 S/R & 120.00 D/R.
