Available in Gen1 or Gen2 versions.

Gen1 springs have 95 lbs. on the seat and 265 lbs. at 12mm of lift. These can handle up to 13+ mm of lift when used with the Gen1 retainers.

Gen2 springs have 55 lbs. on the seat and 180 lbs. at 12mm of lift. These springs can handle up to 14mm of lift when used with the Gen2 retainers.

Gen2 retainers are made of 6AL4V titanium. By using these retainers you can use a higher lift cam due to it's increased install height. By increasing the install height it also allows more retainer to valve seal clearance and prevents spring binding. They also have the same tight fitment that our Gen1 springs and retainers are known for.

Our Gen1 and Gen2 inner and outer springs can be mixed and matched to attain different spring pressures.

Gen1 valve springs - $165
Gen1 titanium retainers - $150
Gen2 valve springs - $165
